* Use 64 bit address in debug information.Bernhard Schommer2016-11-101-0/+7
| | | | | Address constants need to be 64bit also in the debug information. Bug 20335
* */TargetPrinter.ml: wrong comment attached to Init_float32 constantsXavier Leroy2016-04-091-1/+1
| | | | For informative purposes, the FP value of Init_float* constants is printed as a comment in the generated asm file. However, for Init_float32, it was wrongly printed as a double-precision FP instead of a single-precision FP.
* Cleanup of AsmToJSON.Bernhard Schommer2016-03-161-8/+8
| | | | | | Removed unused code, factored out common functions and added an interface file. Bug 18394
* Deactivate warning 27 and added back removed code.Bernhard Schommer2016-03-151-29/+29
| | | | | | The code was mostly there for documentation effort. So warning 27 is deactivated again. Bug 18349
* Code cleanup.Bernhard Schommer2016-03-101-37/+30
| | | | | | Removed some unused variables, functions etc. and resolved some problems which occur if all warnings except 3,4,9 and 29 are active. Bug 18394.

| | | | | | On older version of the binutils the cfi directives are not always supported so we only print cfi_sections if the corresponding .ini setting is set to true.

| * Implemented the usage of DW_AT_ranges for non-contiguous address ranges.Bernhard Schommer2015-10-161-0/+2
| | | | | | | | | | | | | | | | | | | | The gcc produces DW_AT_ranges for non-contiguous address ranges, like compilation units containing functions which are placed in different ELF-sections or lexical scopes that are split up. With this commit CompCert also uses this DWARF v3 feature for gnu backend based targets. In order to ensure backward compability a flag is added which avoids this and produces debug info in DWARF v2 format. Bug 17392.
| * First step to implemente address ranges for the gnu backend.Bernhard Schommer2015-10-151-8/+1
| | | | | | | | | | | | | | | | | | In contrast to the dcc, the gcc uses address ranges to express non-contiguous range of addresses. As a first step we set the start and end addresses for the different address ranges for the compilation unit by using the start and end addresses of functions. Bug 17392.
| * Reworked the section interface for the debug information.Bernhard Schommer2015-10-141-6/+7
| | | | | | | | | | | | Instead of pushing strings around use the actual section. However the string is still used in the Hashtbl. Bug 17392.
| * bug 17392: remove trailing whitespace in source filesMichael Schmidt2015-10-141-35/+35
| |
| * Changed the type of the debug sections with additional string.Bernhard Schommer2015-10-131-5/+11
| | | | | | | | | | | | | | | | Instead of using a string they now take an optional string, which should be none if the backend is not the diab backend and the corresponding section is the text section and Some s with s being the custom section name else. Bug 17392.
| * Implement the usage of the debug_str section for the gcc backend.Bernhard Schommer2015-10-131-1/+3
| | | | | | | | | | | | | | | | GCC prints all string larger than 3 characters in the debug_str section which reduces the size of the debug information since entries containing the same string now map to the same string in the debug_str sections. Bug 17392.

| | | | | | | | | | | | | | | | | | Also: implement __builtin_isel on non-EREF platforms with a branch-free instruction sequence. Also: extend ./configure so that it recognizes "ppc64-" and "e5500-" platforms in addition to "ppc-".

* | | Use Coq strings instead of idents to name external and builtin functions.Xavier Leroy2015-10-111-2/+2
| |/ |/| | | | | | | | | | | | | | | | | The AST.ident type represents source-level identifiers as unique positive numbers. However, the mapping identifiers <-> AST.ident differs between runs of CompCert on different source files. This is problematic when we need to produce or recognize external functions and builtin functions with fixed names, for example: * in $ARCH/Machregs.v to define the register conventions for builtin functions; * in the VST program logic from Princeton to treat thread primitives specially. So far, we used AST.ident_of_string to recover the ident associated with a string. However, this function is defined in OCaml and doesn't execute within Coq. This is a problem both for VST and for future executability of CompCert within Coq. This commit replaces "ident" by "string" in the arguments of EF_external, EF_builtin, EF_inline_asm, EF_annot, and EF_annot_val. This provides stable names for externals and builtins, as needed. For inline asm and annotations, it's a matter of taste, but using strings feels more natural. EF_debug keeps using idents, since some kinds of EF_debug annotations talk about program variables.

* | Change the way the debug sections are printed.Bernhard Schommer2015-09-281-66/+49
| | | | | | | | | | | | If a user uses the #pragma use_section for functions the diab linker requires a separate debug_info section for each entry. This commit adds functionality to emulate this behavior.
* | Added printing the reference address for the LocRef and started refactoring oldBernhard Schommer2015-09-271-12/+0
| | | | | | | | | | | | | | | | Debuging code. The old functions to store the symbol for the Global variables and retrive this is no longer needed since the atom is stored in DebugInformation. Also the Debug.Abbrev module is no longer needed.
* | Added support for the locations of stack allocated local variables.Bernhard Schommer2015-09-251-1/+3
| | | | | | | | | | This commit adds furher support for location information for local variables and starts with the implementation of the debug_loc section.
* | Added support for printing local variables and fixed issue with .textBernhard Schommer2015-09-231-3/+6
| | | | | | | | | | | | Local variables are now added with bogus lexical scopes to reflect the actually lexical scopes. Also this commit fixes assembler problems of the das when a user section with the name ".text" is defined.
* | Record the scope structure during unblocking.Bernhard Schommer2015-09-221-0/+8
| | | | | | | | | | | | Instead of creating separate annotations for the local variables we call the Debug.add_lvar_scope and we construct a mapping from function id + scope id to scope information.
