*	Merge of branch "unsigned-offsets":	xleroy	2011-04-09	1	-5/+7
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	- 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
*	Special case for while(1), for(..., 1, ...) and do ... while(0) loops.	xleroy	2011-03-15	1	-17/+49
\| \| \| \| \| \| \| \|	Don't wait until Constprop to get rid of trivial loop tests; instead, produces better-looking Cminor. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1610 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Float.intoffloat and Float.intuoffloat are now partial functions.	xleroy	2010-10-28	1	-2/+13
\| \| \| \| \| \| \|	(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

	- Csyntax, Csem: source C language has side-effects within expressions, performs implicit casts, and has nondeterministic reduction semantics for expressions - Cstrategy: deterministic red. sem. for the above - Clight: the previous source C language, with pure expressions. Added: temporary variables + implicit casts. - New pass SimplExpr to pull side-effects out of expressions (previously done in untrusted Caml code in cparser/) - Csharpminor: added temporary variables to match Clight. - Cminorgen: adapted, removed cast optimization (moved to back-end) - CastOptim: RTL-level optimization of casts - cparser: transformations Bitfields, StructByValue and StructAssign now work on non-simplified expressions - Added pretty-printers for several intermediate languages, and matching -dxxx command-line flags. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1467 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
