*	Merge of the "princeton" branch:	xleroy	2013-06-16	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	- Define type "block" as "positive" instead of "Z". - Strengthen mem_unchanged_on so that the permissions are identical, instead of possibly increasing. - Move mem_unchanged_on from Events to Memory.Mem. - Define it in terms of mem_contents rather than in terms of Mem.load. - ExportClight: try to name temporaries introduced by SimplExpr - SimplExpr: avoid reusing temporaries between different functions, instead, thread a single generator through all functions. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2276 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Big merge of the newregalloc-int64 branch. Lots of changes in two directions:	xleroy	2013-04-20	1	-48/+86
\| \| \| \| \| \| \| \| \|	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
*	Assorted changes to reduce stack and heap requirements when compiling very ↵	xleroy	2013-03-16	1	-0/+22
\| \| \| \| \| \|	big functions. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2151 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Finished backtracking (cf previous commit) for ARM and PowerPC.	xleroy	2013-03-04	1	-11/+16
\| \| \| \| \| \| \|	ARM: slightly shorter code generated for indirect memory accesses. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2137 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Partial backtracking on previous commit: the "hole in Mach stack frame"	xleroy	2013-03-03	1	-278/+236
\| \| \| \| \| \| \| \|	trick prevents a future mapping of the Mach/Asm call stack as a single block. IA32 is fixed, PowerPC and ARM remains to be done. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2136 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
*	Revised Stacking and Asmgen passes and Mach semantics:	xleroy	2013-03-01	1	-0/+844
	- no more prediction of return addresses (Asmgenretaddr is gone) - instead, punch a hole for the retaddr in Mach stack frame and fill this hole with the return address in the Asmgen proof. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2129 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
