* Big merge of the newregalloc-int64 branch. Lots of changes in two directions:xleroy2013-04-201-67/+56
| | | | | | | | | 1- new register allocator (+ live range splitting, spilling&reloading, etc) based on a posteriori validation using the Rideau-Leroy algorithm 2- support for 64-bit integer arithmetic (type "long long"). git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2200 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* Merge of the nonstrict-ops branch:xleroy2012-01-141-684/+558
| | | | | | | | | | | - Most RTL operators now evaluate to Some Vundef instead of None when undefined behavior occurs. - More aggressive instruction selection. - "Bertotization" of pattern-matchings now implemented by a proper preprocessor. - Cast optimization moved to cfrontend/Cminorgen; removed backend/CastOptim. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1790 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of branch "unsigned-offsets":xleroy2011-04-091-96/+234
| | | | | | | | | | | | | | - 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
* Float.intoffloat and Float.intuoffloat are now partial functions.xleroy2010-10-281-1/+4
| | | | | | | (May fail if float is too big to be converted.) git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1544 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of the reuse-temps branch:xleroy2010-09-021-0/+974
- 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
