* Big merge of the newregalloc-int64 branch. Lots of changes in two directions:Gravatar xleroy2013-04-20
| | | | | | | | | 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

* Globalenvs: allocate one-byte block with permissions Nonempty for eachGravatar xleroy2012-11-12
| | | | | | | | | | | function definition, so that comparisons between function pointers are correctly defined. AST, Globalenvs, and many other files: represent programs as a list of (function or variable) definitions instead of two lists, one for functions and the other for variables. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2067 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

| | | | git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1830 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* - Support for _Alignof(ty) operator from ISO C 2011Gravatar xleroy2012-02-26
| | | | | | | | | | and __alignof__(ty), __alignof__(expr) from GCC. - Resurrected __builtin_memcpy_aligned, useful for files generated by Scade KCG 6. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1827 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Don't print external declarations for builtins.Gravatar xleroy2012-02-18
| | | | git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1818 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of the "volatile" branch:Gravatar xleroy2012-02-04
| | | | | | | | | | | | - native treatment of volatile accesses in CompCert C's semantics - translation of volatile accesses to built-ins in SimplExpr - native treatment of struct assignment and passing struct parameter by value - only passing struct result by value remains emulated - in cparser, remove emulations that are no longer used - added C99's type _Bool and used it to express || and && more efficiently. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1814 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* Added animation of the CompCert C semantics (ccomp -interp)Gravatar xleroy2011-07-28
| | | | | | | | test/regression: int main() so that interpretation works Revised once more implementation of __builtin_memcpy (to check for PPC & ARM) git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1688 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of branches/full-expr-4:Gravatar xleroy2010-08-18
| | | | | | | | | | | | | | | | | | | | | | - 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
* Updated Caml parts to match new representation for global variables.Gravatar xleroy2010-05-26
| | | | | | | */PrintAsm.ml: watch out for large stack frames in Pallocframe. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1349 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Add "fabs" (floating-point absolute value) as a unary operator inGravatar xleroy2010-05-02
| | | | | | | Clight and C#minor. Recognize __builtin_fabs and turn it into this operator. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1329 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

| | | | git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1162 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Cil2Csyntax: added goto and labels; added assignment between structsGravatar xleroy2009-08-16
| | | | | | | | | | | | 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
* Conflict between extraction/CList and cil/obj/xxx/clist on case-insensitive ↵Gravatar xleroy2009-01-29
| | | | | | file systems. Replaced CList by CoqList and likewise for CString and CInt. Removed useless references to CList in hand-written Caml code. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@951 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Reorganized the development, modularizing away machine-dependent parts.Gravatar xleroy2008-12-30
Started to merge the ARM code generator. Started to add support for PowerPC/EABI. Use ocamlbuild to construct executable from Caml files. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@930 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
