*	Big merge of the newregalloc-int64 branch. Lots of changes in two directions:	xleroy	2013-04-20	1	-0/+3
\| \| \| \| \| \| \| \| \|	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
*	Use Flocq for floats	xleroy	2012-06-28	1	-1/+1
\| \| \| \|	git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1939 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	PowerPC: remove the fmadd and fmsub operators/Asm instructions	xleroy	2012-03-07	1	-2/+0
\| \| \| \| \| \| \| \|	(definitely not semantics-preserving; hard to justify). CPragmas: make sure SDAs are not recognized on MacOSX. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1836 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Improved instruction selection for "notint".	xleroy	2012-02-24	1	-0/+3
\| \| \| \| \| \| \|	powerpc/PrintAsm.ml: fixed MacOS X problems with malloc and free git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1824 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Merge of the nonstrict-ops branch:	xleroy	2012-01-14	1	-2/+0
\| \| \| \| \| \| \| \| \| \| \|	- 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
*	Forgot to print Oroli op	xleroy	2011-06-22	1	-0/+4
\| \| \| \|	git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1677 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Merge of the reuse-temps branch:	xleroy	2010-09-02	1	-5/+1
\| \| \| \| \| \| \| \| \| \| \| \|	- 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
*	Merge of branches/full-expr-4:	xleroy	2010-08-18	1	-0/+109
	- 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
