* Remove all temporary files at program exit (#46)Bernhard Schommer2018-01-034-19/+17
| | | | | | | | | Replaced calls to Filename.temp_file by own version Driveraux.tmp_file. The Driveraux.tmp_file function takes care that the temporary files are removed at exit. Consequently there is no need to explicitly remove temp files in Driver.

* Moved constant expansion into Asmexpand. (#40)Bernhard Schommer2017-12-145-318/+419
| | | | | This commit introduces a new pass which is run after the expansion of the builtin functions which performs the expansion and placement of constants inside the function code.

* Export configured architecture to JSON (#38)Michael Schmidt2017-12-132-3/+9
| | | The architecture which was configured is now exported in a new top-level json field.
* Do not pass the env back from for stmt decls. (#42)Bernhard Schommer2017-12-121-7/+7
| | | | | | * Do not pass the env back from for stmt decls. This is the source of issue #211, the environment from the elaboration of the declaration and expressions in the for loop should not be passed back.

| | | | | | | | We simply fully qualify the modules. This is backward compatible.

* | Introduce and use C2C.atom_inline function with 3-valued resultXavier Leroy2017-12-082-14/+11
| | | | | | | | | | | | Instead of two Boolean tests C2C.atom_is_{no,}inline, have a single C2C.atom_inline function that returns one of the three possible values stored in the the a_inline field.
* | Remove unused code. BUg 22642Bernhard Schommer2017-12-082-3/+2

* | Store the different inlining cases.Bernhard Schommer2017-12-083-10/+28
| | | | | | | | | | | | | | In order to correctly support the noinline attribute we must store whether the function was specified with an inline specifer, had a noinline attribute or nothing. Bug 22642

* Inlining of static functions which are only called once. (#37)Bernhard Schommer2017-12-077-13/+105
| | | | | | | | | New inlining heuristic for static functions. Static functions that are only called once can always be inlined, since they can be removed safely after inlining and no call prologue, epilogue, as well as register saving and needs to be generated.
* Optimization for division by one during constant propagation (#39)Michael Schmidt2017-12-058-36/+85
| | | | Signed and unsigned divisions by literal 1 are already optimized away during the Selection phase. This pull request also optimizes those divisions when the 1 divisor is produced by constant propagation.

| * Remove temporary .o files after linking (#36)Xavier Leroy2017-11-271-2/+5
| | | | | | | | | | | | | | When -c is not given, .o files are now generated in /tmp, but they are still not erased. This commit uses an "at_exit" action to erase those temporary .o files before CompCert exits. Using at_exit is easier to implement than explicit erasure (like we do for other temporary files), yet should not result in temporary files lingering in /tmp longer than strictly necessary, since the call to the linker is the last thing that CompCert does before exiting, hence temporary .o files are erased just after the linker returns.

* Issue #208: make value analysis of comparisons more conservative w.r.t. ↵Xavier Leroy2017-11-242-8/+15
| | | | | | | pointers (#209) Comparisons such as "(uintptr_t) &global == 0x1234" are undefined behavior in CompCert but their status in ISO C is unclear and they may occur in real-world code. Make sure they are statically analyzed as Btop.
* Pull request #192: improve the printing of Clight intermediate codeXavier Leroy2017-11-223-10/+29
| | | | So that it looks more like valid C source.
* Added json export for the abstract ARM AssemblerBernhard Schommer2017-11-202-64/+338
| | | | | | | The json export for the abstract ARM Assembler is quite similar to it's PowerPC equivalent expect for the different instruction arguments. Bug 22472
* Moved arm eabi fixup to Asmexpand.Bernhard Schommer2017-11-163-159/+229
| | | | | | | | Instead of expanding the fixup code for incoming and outgoing registers in the TargetPrinter we expand them in Asmexpand. This simplifies the estimate size function and is a prerequisite for the json export. Bug 22472
* New json printing interface.Bernhard Schommer2017-11-144-144/+208
| | | | | The common json export functionallity is moved into an own File. Bug 22472

* Generalize print_init.Bernhard Schommer2017-11-091-1/+40
| | | | | | The powerpc version of print_init can be used without problems for all backends. Bug 22525
* Fix jumptable issue.Bernhard Schommer2017-11-084-5/+8
| | | | | | Instead of using reset_constants use reset_literals which avoids emptying the jumptables. Bug 22525
* Simplifiy handling of constant emmitting.Bernhard Schommer2017-11-084-92/+71
| | | | | | Instead of just storing the constants in a list, they are now stored in a hashtable. This avoids printing of duplicates. Bug 22525

* Also quote \a.Bernhard Schommer2017-10-261-0/+2
| | | | | | This allows for an easier replacement of the binary address and avoids that the user specifies his own binary addresses. Bug 22468

* Prefix ais annotations with location.Bernhard Schommer2017-10-241-2/+4

| * Ensure FunInd or Recdef is imported if functional induction is usedSigurd Schneider2017-07-2015-3/+15
| | | | | | | | | | | | Coq 8.7 does not load FunInd in prelude anymore, so this is necessary. Recdef exports FunInd, so if Recdef is imported, importing FunInd is not required.
* | New support for inserting ais-annotations.Bernhard Schommer2017-10-1931-66/+180
| | | | | | | | | | | | | | | | | | | | | | | | The ais annotations can be inserted via the new ais variants of the builtin annotation. They mainly differe in that they have an address format specifier '%addr' which will be replaced by the adress in the binary. The implementation simply prints a label for the builtin call alongside a the text of the annotation as comment and inserts the annotation together as acii string in a separate section 'ais_annotations' and replaces the usages of the address format specifiers by the address of the label of the builtin call.
* | Check recursively for const for modifiable lvalues (#32)Bernhard Schommer2017-10-171-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Check recursively for const for modifiable lvalues According to 6.3.2.1 a modifiable lvalue is an lvalue that does have a const-qualified type, and if it is a union or structure it does not have any member, including any member of all contained strutures or union, with a const-qualified type. The new check for modifiable lvalue additionally checks this now instead of only testing for toplevel const. Bug 22420
