*	Merge of branch "unsigned-offsets":	xleroy	2011-04-09	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	- 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:	xleroy	2010-09-02	1	-146/+33
\| \| \| \| \| \| \| \| \| \| \| \|	- 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
*	Integers: cleaned up bitwise operations, redefined shr, zero_ext and sign_ext	xleroy	2010-08-21	1	-3/+77
\| \| \| \| \| \| \| \| \|	as bitwise operations rather than arithmetic ones. CastOptimproof: fixed for ARM port. Other files: adapted to changes in Integers. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1472 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Optimisation: addrsymbol + (expr + cst) and addrstack + (expr + cst).	xleroy	2010-05-02	1	-0/+16

*	Merge of the newmem and newextcalls branches:	xleroy	2010-03-07	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	- Revised memory model with concrete representation of ints & floats, and per-byte access permissions - Revised Globalenvs implementation - Matching changes in all languages and proofs. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1282 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Wrong rlwinm generated for 'x mod 1'	xleroy	2010-03-02	1	-53/+53

*	Revised lib/Integers.v to make it parametric w.r.t. word size.	xleroy	2009-11-19	1	-4/+4
\| \| \| \| \| \| \| \| \|	Introduced Int.iwordsize and used it in place of "Int.repr 32" or "Int.repr (Z_of_nat wordsize)". git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1182 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Refactored Selection.v and Selectionproof.v into a machine-dependent part + ↵	xleroy	2009-08-17	1	-0/+1026
	a machine-independent part. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1125 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
