* Merge of the reuse-temps branch:xleroy2010-09-021-2/+2
| | | | | | | | | | | | - 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:xleroy2010-08-181-8/+12
| | | | | | | | | | | | | | | | | | | | | | - 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
* Support for inlined built-ins.xleroy2010-06-291-31/+32
| | | | | | | | | | | | | 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

* Distinguish two kinds of nonterminating behaviors: silent divergencexleroy2009-08-161-4/+6
| | | | | | | | | | | | | | and reactive divergence. As a consequence: - Removed the Enilinf constructor from traceinf (values of traceinf type are always infinite traces). - Traces are now uniquely defined. - Adapted proofs big step -> small step for Clight and Cminor accordingly. - Strengthened results in driver/Complements accordingly. - Added common/Determinism to collect generic results about deterministic semantics. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1123 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
