* Big merge of the newregalloc-int64 branch. Lots of changes in two directions:xleroy2013-04-201-0/+4
| | | | | | | | | 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
* Watch out for behaviors exponential in the nesting of struct/union types. xleroy2013-03-231-28/+3

* Camlcoq.ml: bug in conversion Z to stringv1.12.1xleroy2013-01-291-1/+1
| | | | | | | PrintClight: forgot "$" prefix on temporary names git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2102 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Ported to Coq 8.4pl1. Merge of branches/coq-8.4.xleroy2013-01-291-2/+1

* Globalenvs: allocate one-byte block with permissions Nonempty for eachxleroy2012-11-121-12/+13
| | | | | | | | | | | 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
* Make Clight independent of CompCert C.xleroy2012-10-081-1/+2
| | | | | | | Common parts are factored out in cfrontend/Ctypes.v and cfrontend/Cop.v git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2060 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* - Support for _Alignof(ty) operator from ISO C 2011xleroy2012-02-261-4/+0
| | | | | | | | | | 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.xleroy2012-02-181-2/+4
| | | | git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1818 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of the "volatile" branch:xleroy2012-02-041-19/+3
| | | | | | | | | | | | - 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
* Extraction: map Coq pairs to Caml pairs and Coq chars (type ascii) to Caml charsxleroy2011-10-181-8/+8

* Merge of branches/full-expr-4:xleroy2010-08-181-0/+365
- 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
