* Merge of branch "unsigned-offsets":Gravatar xleroy2011-04-09
| | | | | | | | | | | | | | - In pointer values "Vptr b ofs", interpret "ofs" as an unsigned int. (Fixes issue with wrong comparison of pointers across 0x8000_0000) - Revised Stacking pass to not use negative SP offsets. - Add pointer validity checks to Cminor ... Mach to support the use of memory injections in Stacking. - Cleaned up Stacklayout modules. - IA32: improved code generation for Mgetparam. - ARM: improved code generation for op-immediate instructions. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1632 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of the reuse-temps branch:Gravatar xleroy2010-09-02
- 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
