* Merge of branch "unsigned-offsets":xleroy2011-04-091-4/+8
| | | | | | | | | | | | | | - 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:xleroy2010-09-021-14/+5
| | | | | | | | | | | | - 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
* Support for inlined built-ins.xleroy2010-06-291-1/+3
| | | | | | | | | | | | | AST: add ef_inline flag to external functions. Selection: recognize calls to inlined built-ins and inline them as Sbuiltin. CminorSel to Asm: added Sbuiltin/Ibuiltin instruction. PrintAsm: adapted expansion of builtins. C2Clight: adapted detection of builtins. Conventions: refactored in a machine-independent part (backend/Conventions) and a machine-dependent part (ARCH/SYS/Conventions1). git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1356 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of the newmem and newextcalls branches:xleroy2010-03-071-2/+2

* Cil2Csyntax: added goto and labels; added assignment between structsxleroy2009-08-161-18/+2
| | | | | | | | | | | | Kildall: simplified the interface Constprop, CSE, Allocation, Linearize: updated for the new Kildall RTL, LTL: removed the well-formedness condition on the CFG, it is no longer necessary with the new Kildall and it is problematic for validated optimizations. Maps: more efficient implementation of PTree.fold. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1124 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* - Added alignment constraints to memory loads and stores.xleroy2009-01-111-3/+1
| | | | | | | | | | | - In Cminor and below, removed pointer validity check in semantics of comparisons, so that evaluation of expressions is independent of memory state. - In Cminor and below, removed "alloc" instruction. - Cleaned up commented-away parts. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@945 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
