They are represented as the type <a href="Cil.html#TYPEexp"><code class="code">Cil.exp</code></a>. There are several -interesting aspects of CIL expressions: -<p> - - Integer and floating point constants can carry their textual representation. -This way the integer 15 can be printed as 0xF if that is how it occurred in the -source. -<p> - - CIL uses 64 bits to represent the integer constants and also stores the width -of the integer type. Care must be taken to ensure that the constant is -representable with the given width. Use the functions <a href="Cil.html#VALkinteger"><code class="code">Cil.kinteger</code></a>, -<a href="Cil.html#VALkinteger64"><code class="code">Cil.kinteger64</code></a> and <a href="Cil.html#VALinteger"><code class="code">Cil.integer</code></a> to construct constant -expressions. CIL predefines the constants <a href="Cil.html#VALzero"><code class="code">Cil.zero</code></a>, -<a href="Cil.html#VALone"><code class="code">Cil.one</code></a> and <a href="Cil.html#VALmone"><code class="code">Cil.mone</code></a> (for -1). -<p> - - Use the functions <a href="Cil.html#VALisConstant"><code class="code">Cil.isConstant</code></a> and <a href="Cil.html#VALisInteger"><code class="code">Cil.isInteger</code></a> to test if -an expression is a constant and a constant integer respectively. -<p> - - CIL keeps the type of all unary and binary expressions.

This range -is denoted as a host object along with an offset within the object. The -host object can be of two kinds: a local or global variable, or an object -whose address is in a pointer expression. We distinguish the two cases so -that we can tell quickly whether we are accessing some component of a -variable directly or we are accessing a memory location through a pointer. -To make it easy to -tell what an lvalue means CIL represents lvalues as a host object and an -offset (see <a href="Cil.html#TYPElval"><code class="code">Cil.lval</code></a>).

And <TT>maincil.ml</TT> has - been renamed <TT>main.ml</TT>. -<LI CLASS="li-itemize"><B>May 18, 2006</B>: Added a new module <A HREF="api/Cfg.html">Cfg</A> to compute the - control-flow graph. Unlike the older <A HREF="api/Cil.html#VALcomputeCFGInfo">Cil.computeCFGInfo</A>, - the new version does not modify the code. -<LI CLASS="li-itemize"><B>May 18, 2006</B>: Added several new analyses: reaching - definitions, available expressions, liveness analysis, and dead code - elimination. See Section <A HREF="ext.html#sec-Extension">8</A>. -<LI CLASS="li-itemize"><B>May 2, 2006</B>: Added a flag <TT>--noInsertImplicitCasts</TT>. - When this flag is used, CIL code will only include casts inserted by - the programmer.

This is the default behavior in unoptimized gcc and - MSVC, but the order of evaluation is undefined when using - optimizations, unless you apply this CIL transformation. This flag - does not affect the order of evaluation of e.g. binary operators, - which remains undefined.

Added code - during configuration to detect which is the case. -<LI CLASS="li-itemize"><B>January 7, 2004</B>: <B>Released version 1.2.3</B> -<LI CLASS="li-itemize"><B>January 7, 2004</B>: Changed the alpha renamer to be less -conservative.

If given, it will appear as a "thread" attribute at the top of the -type of the declared object. Treatment is very similar to "__declspec(...)" -in MSVC<BR> -<BR> -<LI CLASS="li-itemize"><B>July 8, 2003</B>: Fixed some of the __alignof computations.

The main advantage of CIL is that -it compiles all valid C programs into a few core constructs with a very clean -semantics. Also CIL has a syntax-directed type system that makes it easy to -analyze and manipulate C programs. Furthermore, the CIL front-end is able to -process not only ANSI-C programs but also those using Microsoft C or GNU C -extensions. If you do not use CIL and want instead to use just a C parser and -analyze programs expressed as abstract-syntax trees then your analysis will -have to handle a lot of ugly corners of the language (let alone the fact that -parsing C itself is not a trivial task). See Section <A HREF="#sec-simplec">16</A> for some -examples of such extreme programs that CIL simplifies for you.<BR> -<BR> -In essence, CIL is a highly-structured, “clean” subset of C. CIL features a -reduced number of syntactic and conceptual forms. For example, all looping -constructs are reduced to a single form, all function bodies are given -explicit <TT>return</TT> statements, syntactic sugar like <TT>"->"</TT> is -eliminated and function arguments with array types become pointers. (For an -extensive list of how CIL simplifies C programs, see Section <A HREF="#sec-cabs2cil">4</A>.) -This reduces the number of cases that must be considered when manipulating a C -program. CIL also separates type declarations from code and flattens scopes -within function bodies. This structures the program in a manner more amenable -to rapid analysis and transformation. CIL computes the types of all program -expressions, and makes all type promotions and casts explicit. CIL supports -all GCC and MSVC extensions except for nested functions and complex numbers. -Finally, CIL organizes C's imperative features into expressions, instructions -and statements based on the presence and absence of side-effects and -control-flow. Every statement can be annotated with successor and predecessor -information. Thus CIL provides an integrated program representation that can -be used with routines that require an AST (e.g. type-based analyses and -pretty-printers), as well as with routines that require a CFG (e.g., dataflow -analyses). CIL also supports even lower-level representations (e.g., -three-address code), see Section <A HREF="#sec-Extension">8</A>. <BR> -<BR> -CIL comes accompanied by a number of Perl scripts that perform generally -useful operations on code: -<UL CLASS="itemize"><LI CLASS="li-itemize"> -A <A HREF="#sec-driver">driver</A> which behaves as either the <TT>gcc</TT> or -Microsoft VC compiler and can invoke the preprocessor followed by the CIL -application. The advantage of this script is that you can easily use CIL and -the analyses written for CIL with existing make files. -<LI CLASS="li-itemize">A <A HREF="#sec-merger">whole-program merger</A> that you can use as a -replacement for your compiler and it learns all the files you compile when you -make a project and merges all of the preprocessed source files into a single -one. This makes it easy to do whole-program analysis. -<LI CLASS="li-itemize">A <A HREF="#sec-patcher">patcher</A> makes it easy to create modified -copies of the system include files. The CIL driver can then be told to use -these patched copies instead of the standard ones. -</UL> -CIL has been tested very extensively. It is able to process the SPECINT95 -benchmarks, the Linux kernel, GIMP and other open-source projects. All of -these programs are compiled to the simple CIL and then passed to <TT>gcc</TT> and -they still run! We consider the compilation of Linux a major feat especially -since Linux contains many of the ugly GCC extensions (see Section <A HREF="#sec-ugly-gcc">16.2</A>). -This adds to about 1,000,000 lines of code that we tested it on. It is also -able to process the few Microsoft NT device drivers that we have had access -to. CIL was tested against GCC's c-torture testsuite and (except for the tests -involving complex numbers and inner functions, which CIL does not currently -implement) CIL passes most of the tests. Specifically CIL fails 23 tests out -of the 904 c-torture tests that it should pass. GCC itself fails 19 tests. A -total of 1400 regression test cases are run automatically on each change to -the CIL sources.<BR> -<BR> -CIL is relatively independent on the underlying machine and compiler. When -you build it CIL will configure itself according to the underlying compiler. -However, CIL has only been tested on Intel x86 using the gcc compiler on Linux -and cygwin and using the MS Visual C compiler. (See below for specific -versions of these compilers that we have used CIL for.)<BR> -<BR> -The largest application we have used CIL for is -<A HREF="javascript:loadTop('../ccured/index.html')">CCured</A>, a compiler that compiles C code into -type-safe code by analyzing your pointer usage and inserting runtime checks in -the places that cannot be guaranteed statically to be type safe. <BR> -<BR> -You can also use CIL to “compile” code that uses GCC extensions (e.g. the -Linux kernel) into standard C code.<BR> -<BR> -CIL also comes accompanies by a growing library of extensions (see -Section <A HREF="#sec-Extension">8</A>).

The visiting engine scans depth-first -the structure of a CIL program and at each node is queries a user-provided -visitor structure whether it should do one of the following operations: -<UL CLASS="itemize"><LI CLASS="li-itemize"> -Ignore this node and all its descendants -<LI CLASS="li-itemize">Descend into all of the children and when done rebuild the node if any -of the children have changed. -<LI CLASS="li-itemize">Replace the subtree rooted at the node with another tree. -<LI CLASS="li-itemize">Replace the subtree with another tree, then descend into the children -and rebuild the node if necessary and then invoke a user-specified function. -<LI CLASS="li-itemize">In addition to all of the above actions then visitor can specify that -some instructions should be queued to be inserted before the current -instruction or statement being visited. -</UL> -By writing visitors you can customize the program traversal and -transformation. One major limitation of the visiting engine is that it does -not propagate information from one node to another. Each visitor must use its -own private data to achieve this effect if necessary. <BR> -<BR> -Each visitor is an object that is an instance of a class of type <A HREF="api/Cil.cilVisitor.html#.">Cil.cilVisitor..</A> -The most convenient way to obtain such classes is to specialize the -<A HREF="api/Cil.nopCilVisitor.html#c">Cil.nopCilVisitor.c</A>lass (which just traverses the tree doing -nothing). Any given specialization typically overrides only a few of the -methods. Take a look for example at the visitor defined in the module -<TT>logwrites.ml</TT>. Another, more elaborate example of a visitor is the -[copyFunctionVisitor] defined in <TT>cil.ml</TT>.<BR> -<BR> -Once you have defined a visitor you can invoke it with one of the functions: -<UL CLASS="itemize"><LI CLASS="li-itemize"> -<A HREF="api/Cil.html#VALvisitCilFile">Cil.visitCilFile</A> or <A HREF="api/Cil.html#VALvisitCilFileSameGlobals">Cil.visitCilFileSameGlobals</A> - visit a file -<LI CLASS="li-itemize"><A HREF="api/Cil.html#VALvisitCilGlobal">Cil.visitCilGlobal</A> - visit a global -<LI CLASS="li-itemize"><A HREF="api/Cil.html#VALvisitCilFunction">Cil.visitCilFunction</A> - visit a function definition -<LI CLASS="li-itemize"><A HREF="api/Cil.html#VALvisitCilExp">Cil.visitCilExp</A> - visit an expression -<LI CLASS="li-itemize"><A HREF="api/Cil.html#VALvisitCilLval">Cil.visitCilLval</A> - visit an lvalue -<LI CLASS="li-itemize"><A HREF="api/Cil.html#VALvisitCilInstr">Cil.visitCilInstr</A> - visit an instruction -<LI CLASS="li-itemize"><A HREF="api/Cil.html#VALvisitCilStmt">Cil.visitCilStmt</A> - visit a statement -<LI CLASS="li-itemize"><A HREF="api/Cil.html#VALvisitCilType">Cil.visitCilType</A> - visit a type.

The pattern is a string that uses -the C syntax to represent C language elements. For example, the following -code: -<PRE CLASS="verbatim"><FONT COLOR=blue> -Formatcil.cType "void * const (*)(int x)" -</FONT></PRE> -is an alternative way to construct the internal representation of the type of pointer to function -with an integer argument and a void * const as result: -<PRE CLASS="verbatim"><FONT COLOR=blue> -TPtr(TFun(TVoid [Attr("const", [])], - [ ("x", TInt(IInt, []), []) ], false, []), []) -</FONT></PRE> -The advantage of the interpreted constructors is that you can use familiar C -syntax to construct CIL abstract-syntax trees. <BR> -<BR> -You can construct this way types, lvalues, expressions, instructions and -statements. The pattern string can also contain a number of placeholders that -are replaced during construction with CIL items passed as additional argument -to the construction function. For example, the <TT>%e:id</TT> placeholder means -that the argument labeled “id” (expected to be of form <TT>Fe exp</TT>) will -supply the expression to replace the placeholder. For example, the following -code constructs an increment instruction at location <TT>loc</TT>: -<PRE CLASS="verbatim"><FONT COLOR=blue> -Formatcil.cInstr "%v:x = %v:x + %e:something" - loc - [ ("something", Fe some_exp); - ("x", Fv some_varinfo) ] -</FONT></PRE> -An alternative way to construct the same CIL instruction is: -<PRE CLASS="verbatim"><FONT COLOR=blue> -Set((Var some_varinfo, NoOffset), - BinOp(PlusA, Lval (Var some_varinfo, NoOffset), - some_exp, intType), - loc) -</FONT></PRE> -See <A HREF="api/Cil.html#TYPEformatArg">Cil.formatArg</A> for a definition of the placeholders that are -understood.<BR> -<BR> -A dual feature is the interpreted deconstructors. This can be used to test -whether a CIL construct has a certain form: -<PRE CLASS="verbatim"><FONT COLOR=blue> -Formatcil.dType "void * const (*)(int x)" t -</FONT></PRE> -will test whether the actual argument <TT>t</TT> is indeed a function pointer of -the required type. If it is then the result is <TT>Some []</TT> otherwise it is -<TT>None</TT>. Furthermore, for the purpose of the interpreted deconstructors -placeholders in patterns match anything of the right type. For example, -<PRE CLASS="verbatim"><FONT COLOR=blue> -Formatcil.dType "void * (*)(%F:t)" t -</FONT></PRE> -will match any function pointer type, independent of the type and number of -the formals. If the match succeeds the result is <TT>Some [ FF forms ]</TT> where -<TT>forms</TT> is a list of names and types of the formals. Note that each member -in the resulting list corresponds positionally to a placeholder in the -pattern.<BR> -<BR> -The interpreted constructors and deconstructors do not support the complete C -syntax, but only a substantial fragment chosen to simplify the parsing.

There are two tasks that a merger must perform: -<OL CLASS="enumerate" type=1><LI CLASS="li-enumerate"> -Detect what are all the sources that make a project and with what -compiler arguments they are compiled.<BR> -<BR> -<LI CLASS="li-enumerate">Merge all of the source files into a single file. -</OL> -For the first task the merger impersonates a compiler and a linker (both a -GCC and a Microsoft Visual C mode are supported) and it expects to be invoked -(from a build script or a Makefile) on all sources of the project. When -invoked to compile a source the merger just preprocesses the source and saves -the result using the name of the requested object file. By preprocessing at -this time the merger is able to take into account variations in the command -line arguments that affect preprocessing of different source files.<BR> -<BR> -When the merger is invoked to link a number of object files it collects the -preprocessed sources that were stored with the names of the object files, and -invokes the merger proper. Note that arguments that affect the compilation or -linking must be the same for all source files.<BR> -<BR> -For the second task, the merger essentially concatenates the preprocessed -sources with care to rename conflicting file-local declarations (we call this -process alpha-conversion of a file). The merger also attempts to remove -duplicate global declarations and definitions. Specifically the following -actions are taken: -<UL CLASS="itemize"><LI CLASS="li-itemize"> -File-scope names (<TT>static</TT> globals, names of types defined with -<TT>typedef</TT>, and structure/union/enumeration tags) are given new names if they -conflict with declarations from previously processed sources. The new name is -formed by appending the suffix <TT>___n</TT>, where <TT>n</TT> is a unique integer -identifier. Then the new names are applied to their occurrences in the file. <BR> -<BR> -<LI CLASS="li-itemize">Non-static declarations and definitions of globals are never renamed. -But we try to remove duplicate ones. Equality of globals is detected by -comparing the printed form of the global (ignoring the line number directives) -after the body has been alpha-converted. This process is intended to remove -those declarations (e.g. function prototypes) that originate from the same -include file. Similarly, we try to eliminate duplicate definitions of -<TT>inline</TT> functions, since these occasionally appear in include files.<BR> -<BR> -<LI CLASS="li-itemize">The types of all global declarations with the same name from all files -are compared for type isomorphism. During this process, the merger detects all -those isomorphisms between structures and type definitions that are <B>required</B> for the merged program to be legal. Such structure tags and -typenames are coalesced and given the same name. <BR> -<BR> -<LI CLASS="li-itemize">Besides the structure tags and type names that are required to be -isomorphic, the merger also tries to coalesce definitions of structures and -types with the same name from different file.

Also fixed printing of attributes on enum types. -<LI CLASS="li-itemize"><B>March 30, 2006</B>: Fix for <TT>rmtemps.ml</TT>, which deletes - unused inline functions. When in <TT>gcc</TT> mode CIL now leaves all - inline functions in place, since <TT>gcc</TT> treats these as externally - visible. -<LI CLASS="li-itemize"><B>March 15, 2006</B>: Fix for <TT>typeof(<I>e</I>)</TT> when <I>e</I> has type - <TT>void</TT>. -<LI CLASS="li-itemize"><B>March 3, 2006</B>: Assume inline assembly instructions can - fall through for the purposes of adding return statements.

This is the default behavior in unoptimized gcc and - MSVC, but the order of evaluation is undefined when using - optimizations, unless you apply this CIL transformation. This flag - does not affect the order of evaluation of e.g. binary operators, - which remains undefined. Thanks to Nathan Cooprider for the patch. -<LI CLASS="li-itemize"><B>August 9, 2005</B>: Fixed merging when there are more than 20 - input files. -<LI CLASS="li-itemize"><B>August 3, 2005</B>: When merging, it is now an error to - declare the same global variable twice with different initializers. -<LI CLASS="li-itemize"><B>July 27, 2005</B>: Fixed bug in transparent unions. -<LI CLASS="li-itemize"><B>July 27, 2005</B>: Fixed bug in collectInitializer.

Now we make sure that the initializers -are run in the proper order with respect to the statements. -<LI CLASS="li-itemize"><B>April 5, 2004</B>: Fixed a bug in the merger. The merger was keeping -separate alpha renaming talbes (namespaces) for variables and types. This -means that it might end up with a type and a variable named the same way, if -they come from different files, which breaks an important CIL invariant. -<LI CLASS="li-itemize"><B>March 11, 2004</B> : Fixed a bug in the Cil.copyFunction function. The -new local variables were not getting fresh IDs. -<LI CLASS="li-itemize"><B>March 5, 2004</B>: Fixed a bug in the handling of static function - prototypes in a block scope.

Thanks, Manos Renieris. -<LI CLASS="li-itemize"><B>April 16, 2003</B>: Reworked management of - temporary/intermediate output files in Perl driver scripts. Default - behavior is now to remove all such files. To keep intermediate - files, use one of the following existing flags: - <UL CLASS="itemize"><LI CLASS="li-itemize"> - <TT>--keepmerged</TT> for the single-file merge of all sources - <LI CLASS="li-itemize"><TT>--keep=<<I>dir</I></TT><TT>></TT> for various other CIL and - CCured output files - <LI CLASS="li-itemize"><TT>--save-temps</TT> for various gcc intermediate files; MSVC - has no equivalent option - </UL> - As part of this change, some intermediate files have changed their - names slightly so that new suffixes are always preceded by a - period. For example, CCured output that used to appear in - “<TT>foocured.c</TT>” now appears in “<TT>foo.cured.c</TT>”. -<LI CLASS="li-itemize"><B>April 7, 2003</B>: Changed the representation of the <A HREF="api/Cil.html#VALGVar">Cil.GVar</A> -global constructor. Now it is possible to update the initializer without -reconstructing the global (which in turn it would require reconstructing the -list of globals that make up a program). We did this because it is often -tempting to use <A HREF="api/Cil.html#VALvisitCilFileSameGlobals">Cil.visitCilFileSameGlobals</A> and the <A HREF="api/Cil.html#VALGVar">Cil.GVar</A> -was the only global that could not be updated in place. -<LI CLASS="li-itemize"><B>April 6, 2003</B>: Reimplemented parts of the cilly.pl script to make -it more robust in the presence of complex compiler arguments. -<LI CLASS="li-itemize"><B>March 10, 2003</B>: <B>Released version 1.0.9</B> -<LI CLASS="li-itemize"><B>March 10, 2003</B>: Unified and documented a large number of CIL -Library Modules: oneret, simplemem, makecfg, heapify, stackguard, partial. -Also documented the main client interface for the pointer analysis. -<LI CLASS="li-itemize"><B>February 18, 2003</B>: Fixed a bug in logwrites that was causing it -to produce invalid C code on writes to bitfields.

Relaxed the semantics of the patterns for variables. -<LI CLASS="li-itemize"><B>January 17, 2003</B>: Added built-in prototypes for the gcc built-in - functions. Changed the <TT>pGlobal</TT> method in the printers to print the - carriage return as well. -<LI CLASS="li-itemize"><B>January 9, 2003</B>: Reworked lexer and parser's strategy for - tracking source file names and line numbers to more closely match - typical native compiler behavior. The visible CIL interface is - unchanged. -<LI CLASS="li-itemize"><B>January 9, 2003</B>: Changed the interface to the alpha convertor. Now -you can pass a list where it will record undo information that you can use to -revert the changes that it makes to the scope tables. -<LI CLASS="li-itemize"><B>January 6, 2003</B>: <B>Released version 1.0.5</B> -<LI CLASS="li-itemize"><B>January 4, 2003</B>: Changed the interface for the Formatcil module. - Now the placeholders in the pattern have names. Also expanded the - documentation of the Formatcil module. - Now the placeholders in the pattern have names. -<LI CLASS="li-itemize"><B>January 3, 2003</B>: Extended the <TT>rmtmps</TT> module to also remove - unused labels that are generated in the conversion to CIL. This reduces the - number of warnings that you get from <TT>cgcc</TT> afterwards. -<LI CLASS="li-itemize"><B>December 17, 2002</B>: Fixed a few bugs in CIL related to the - representation of string literals. The standard says that a string literal - is an array. In CIL, a string literal has type pointer to character. This is - Ok, except as an argument of sizeof. To support this exception, we have - added to CIL the expression constructor SizeOfStr.

The main advantage of CIL is that -it compiles all valid C programs into a few core constructs with a very clean -semantics. Also CIL has a syntax-directed type system that makes it easy to -analyze and manipulate C programs. Furthermore, the CIL front-end is able to -process not only ANSI-C programs but also those using Microsoft C or GNU C -extensions. If you do not use CIL and want instead to use just a C parser and -analyze programs expressed as abstract-syntax trees then your analysis will -have to handle a lot of ugly corners of the language (let alone the fact that -parsing C itself is not a trivial task). See Section <A HREF="cil016.html#sec-simplec">16</A> for some -examples of such extreme programs that CIL simplifies for you.<BR> -<BR> -In essence, CIL is a highly-structured, “clean” subset of C. CIL features a -reduced number of syntactic and conceptual forms. For example, all looping -constructs are reduced to a single form, all function bodies are given -explicit <TT>return</TT> statements, syntactic sugar like <TT>"->"</TT> is -eliminated and function arguments with array types become pointers. (For an -extensive list of how CIL simplifies C programs, see Section <A HREF="cil004.html#sec-cabs2cil">4</A>.) -This reduces the number of cases that must be considered when manipulating a C -program. CIL also separates type declarations from code and flattens scopes -within function bodies. This structures the program in a manner more amenable -to rapid analysis and transformation. CIL computes the types of all program -expressions, and makes all type promotions and casts explicit. CIL supports -all GCC and MSVC extensions except for nested functions and complex numbers. -Finally, CIL organizes C's imperative features into expressions, instructions -and statements based on the presence and absence of side-effects and -control-flow. Every statement can be annotated with successor and predecessor -information. Thus CIL provides an integrated program representation that can -be used with routines that require an AST (e.g. type-based analyses and -pretty-printers), as well as with routines that require a CFG (e.g., dataflow -analyses). CIL also supports even lower-level representations (e.g., -three-address code), see Section <A HREF="ext.html#sec-Extension">8</A>. <BR> -<BR> -CIL comes accompanied by a number of Perl scripts that perform generally -useful operations on code: -<UL CLASS="itemize"><LI CLASS="li-itemize"> -A <A HREF="cil007.html#sec-driver">driver</A> which behaves as either the <TT>gcc</TT> or -Microsoft VC compiler and can invoke the preprocessor followed by the CIL -application. The advantage of this script is that you can easily use CIL and -the analyses written for CIL with existing make files. -<LI CLASS="li-itemize">A <A HREF="merger.html#sec-merger">whole-program merger</A> that you can use as a -replacement for your compiler and it learns all the files you compile when you -make a project and merges all of the preprocessed source files into a single -one. This makes it easy to do whole-program analysis. -<LI CLASS="li-itemize">A <A HREF="patcher.html#sec-patcher">patcher</A> makes it easy to create modified -copies of the system include files. The CIL driver can then be told to use -these patched copies instead of the standard ones. -</UL> -CIL has been tested very extensively. It is able to process the SPECINT95 -benchmarks, the Linux kernel, GIMP and other open-source projects. All of -these programs are compiled to the simple CIL and then passed to <TT>gcc</TT> and -they still run! We consider the compilation of Linux a major feat especially -since Linux contains many of the ugly GCC extensions (see Section <A HREF="cil016.html#sec-ugly-gcc">16.2</A>). -This adds to about 1,000,000 lines of code that we tested it on. It is also -able to process the few Microsoft NT device drivers that we have had access -to. CIL was tested against GCC's c-torture testsuite and (except for the tests -involving complex numbers and inner functions, which CIL does not currently -implement) CIL passes most of the tests. Specifically CIL fails 23 tests out -of the 904 c-torture tests that it should pass. GCC itself fails 19 tests. A -total of 1400 regression test cases are run automatically on each change to -the CIL sources.<BR> -<BR> -CIL is relatively independent on the underlying machine and compiler. When -you build it CIL will configure itself according to the underlying compiler. -However, CIL has only been tested on Intel x86 using the gcc compiler on Linux -and cygwin and using the MS Visual C compiler. (See below for specific -versions of these compilers that we have used CIL for.)<BR> -<BR> -The largest application we have used CIL for is -<A HREF="javascript:loadTop('../ccured/index.html')">CCured</A>, a compiler that compiles C code into -type-safe code by analyzing your pointer usage and inserting runtime checks in -the places that cannot be guaranteed statically to be type safe. <BR> -<BR> -You can also use CIL to “compile” code that uses GCC extensions (e.g. the -Linux kernel) into standard C code.<BR> -<BR> -CIL also comes accompanies by a growing library of extensions (see -Section <A HREF="ext.html#sec-Extension">8</A>).

The pattern is a string that uses -the C syntax to represent C language elements. For example, the following -code: -<PRE CLASS="verbatim"><FONT COLOR=blue> -Formatcil.cType "void * const (*)(int x)" -</FONT></PRE> -is an alternative way to construct the internal representation of the type of pointer to function -with an integer argument and a void * const as result: -<PRE CLASS="verbatim"><FONT COLOR=blue> -TPtr(TFun(TVoid [Attr("const", [])], - [ ("x", TInt(IInt, []), []) ], false, []), []) -</FONT></PRE> -The advantage of the interpreted constructors is that you can use familiar C -syntax to construct CIL abstract-syntax trees. <BR> -<BR> -You can construct this way types, lvalues, expressions, instructions and -statements. The pattern string can also contain a number of placeholders that -are replaced during construction with CIL items passed as additional argument -to the construction function. For example, the <TT>%e:id</TT> placeholder means -that the argument labeled “id” (expected to be of form <TT>Fe exp</TT>) will -supply the expression to replace the placeholder. For example, the following -code constructs an increment instruction at location <TT>loc</TT>: -<PRE CLASS="verbatim"><FONT COLOR=blue> -Formatcil.cInstr "%v:x = %v:x + %e:something" - loc - [ ("something", Fe some_exp); - ("x", Fv some_varinfo) ] -</FONT></PRE> -An alternative way to construct the same CIL instruction is: -<PRE CLASS="verbatim"><FONT COLOR=blue> -Set((Var some_varinfo, NoOffset), - BinOp(PlusA, Lval (Var some_varinfo, NoOffset), - some_exp, intType), - loc) -</FONT></PRE> -See <A HREF="api/Cil.html#TYPEformatArg">Cil.formatArg</A> for a definition of the placeholders that are -understood.<BR> -<BR> -A dual feature is the interpreted deconstructors. This can be used to test -whether a CIL construct has a certain form: -<PRE CLASS="verbatim"><FONT COLOR=blue> -Formatcil.dType "void * const (*)(int x)" t -</FONT></PRE> -will test whether the actual argument <TT>t</TT> is indeed a function pointer of -the required type. If it is then the result is <TT>Some []</TT> otherwise it is -<TT>None</TT>. Furthermore, for the purpose of the interpreted deconstructors -placeholders in patterns match anything of the right type. For example, -<PRE CLASS="verbatim"><FONT COLOR=blue> -Formatcil.dType "void * (*)(%F:t)" t -</FONT></PRE> -will match any function pointer type, independent of the type and number of -the formals. If the match succeeds the result is <TT>Some [ FF forms ]</TT> where -<TT>forms</TT> is a list of names and types of the formals. Note that each member -in the resulting list corresponds positionally to a placeholder in the -pattern.<BR> -<BR> -The interpreted constructors and deconstructors do not support the complete C -syntax, but only a substantial fragment chosen to simplify the parsing.
