*	Remove some useless "Require".	xleroy	2012-12-30	1	-1/+0
\| \| \| \| \| \| \|	Update ARM port. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2085 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Merge of the nonstrict-ops branch:	xleroy	2012-01-14	1	-4/+9
\| \| \| \| \| \| \| \| \| \| \|	- 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

\| \| \| \| \| \| \| \|	ia32: lift restriction that 1st arg of ops cannot be ECX (could be useful for a future, better reloading strategy) git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1711 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	IA32 port: more faithful treatment of pseudoregister ST0.	xleroy	2011-08-08	1	-3/+3
\| \| \| \| \| \| \|	Related general change: support for destroyed_at_moves. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1700 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

*	Renamed Machconcr into Machsem.	xleroy	2011-04-09	1	-53/+53
\| \| \| \| \| \| \| \|	Removed Machabstr and Machabstr2concr, now useless following the reengineering of Stacking. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1633 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Merge of branch "unsigned-offsets":	xleroy	2011-04-09	1	-66/+110
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	- 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
*	Improvements for int8 and int16 stores	xleroy	2010-09-10	1	-1/+3

*	Merge of the reuse-temps branch:	xleroy	2010-09-02	1	-0/+1229
	- 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
