* Print cfi_sections only if cfi is supported.Bernhard Schommer2015-12-151-3/+3
| | | | | | 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 Schommer2015-10-162-0/+3
| | | | | | | | | | | | | | | | | | | | 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.

| * 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 Schommer2015-10-132-2/+5
| | | | | | | | | | | | | | | | 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.
| * Fix minor typo introduced by refactoring of debug information.Bernhard Schommer2015-10-121-1/+1
| | | | | | | | | | The base register for the stack allocated variables should be r1 and not r2 under powerpc. Bug 17392

| * | Use PowerPC 64 bits instructions (when available) for int<->FP conversions.Xavier Leroy2015-09-1314-14/+170
| | | | | | | | | | | | | | | | | | 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 Leroy2015-10-113-25/+14
| |/ |/| | | | | | | | | | | | | | | | | 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.
* | Filled in missing functions for debug information on ia32.Bernhard Schommer2015-10-091-23/+2
| | | | | | | | | | | | Like for arm and ppc the functions for section names and start and end addresses of compilation units are defined and the print_annot function is moved to Asmexpandaux.ml.
* | Fixed syntax error and added Section_debug_line to the Json serializer.Bernhard Schommer2015-10-092-1/+2

* | Filled in the rest of the funciton needed for thte debug info under arm.Bernhard Schommer2015-10-092-13/+8
| | | | | | | | | | | | The name_of_section function no returns the correct name for the debug sections, the prologue and epilogue directives are added and the labels for the live ranges are introduced in the Asmexpand pass.
* | Added versions of the tranform_* functions in AST to work with functionsBernhard Schommer2015-10-081-22/+1
| | | | | | | | | | | | | | | | taking the ident as argument. This functions are currently not used inside the proven part but it is nice to have them already there, when they are used by some future pass. They also come equiped with the corresponding proofs.
* | Moved expandation of debug information to Asmexpandaux.Bernhard Schommer2015-10-081-66/+5
| | | | | | | | | | | | The function is generalized to work for all backends and takes as additional arguments functions for the printing of the simple instructions and the translation function for the arguments.
