* Make Archi.ptr64 always computable, and reorganize files accordingly: ia32 ↵Xavier Leroy2016-10-271-18/+0
| | | | | | | | | | | | -> x86/x86_32/x86_64 Having Archi.ptr64 as an opaque Parameter that is determined at run-time depending on compcert.ini is problematic for applications such as VST where functions such as Ctypes.sizeof must compute within Coq. This commit introduces two versions of the Archi.v file, one for x86 32 bits (with ptr64 := false), one for x86 64 bits (with ptr64 := true). Unlike previous approaches, no other file is duplicated between these two variants of x86. While we are at it, I renamed "ia32" into "x86" everywhere. "ia32" is Intel speak for the 32-bit architecture. It is not a good name to describe both the 32 and 64 bit architectures. Finally, .depend is no longer under version control and is regenerated when the target architecture changes. That's because the location of Archi.v differs between the ports that have 32/64 bit variants (x86 so far) and the ports that have only one bitsize (ARM and PowerPC so far).
* Remove code that will is deprecated in ocaml 4.03Bernhard Schommer2016-06-211-1/+1
| | | | | | | | Most of the code can be String.uppercase usages can either be replaced by a more specialized version of coqstring_of_camlstring (which is also slightly more effecient) or by specialized checks that reject wrong code earlier. Bug 19187
* Extended inline asm: revised treatment of clobbered registers.Xavier Leroy2015-05-091-1/+0
| | | | | | | | | | - Treat clobbered registers as being destroyed by EF_inline_asm builtins (which is the truth, semantically). - To enable the above, represent clobbers as Coq strings rather than idents and move register_by_name from Machregsaux.ml to Machregs.v. - Side benefit: more efficient implementation of Machregsaux.name_of_register. -# Please enter the commit message for your changes.

* Merge of the reuse-temps branch:xleroy2010-09-021-0/+17
- Reload temporaries are marked as destroyed (set to Vundef) across operations in the semantics of LTL, LTLin, Linear and Mach, allowing Asmgen to reuse them. - Added IA32 port. - Cleaned up float conversions and axiomatization of floats. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1499 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
