* powerpc/PrintAsm.ml arm/PrintAsm.ml: updated (no label elimination).xleroy2011-05-081-3/+4
| | | | | | | | | | Added -dmach option and corresponding printer for Mach code. CleanupLabelsproof.v: fixed for ARM Driver.ml: -E sends output to stdout; support for .s and .S source files. cparser/Elab.ml: spurious comment deleted. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1648 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Added pass CleanupLabels to remove unreferenced labels in a proved way.xleroy2011-05-081-3/+11
| | | | | | | | | | ia32/PrintAsm.ml: simplified accordingly; other PrintAsm.ml to be fixed. ia32/Asm.v: Pmov_ri can undef flags (if translated to xor) cparser/Ceval.ml: treat ~ in constant exprs git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1647 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Renamed Machconcr into Machsem.xleroy2011-04-091-0/+1
| | | | | | | | Removed Machabstr and Machabstr2concr, now useless following the reengineering of Stacking. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1633 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of branch "unsigned-offsets":xleroy2011-04-091-2/+0
| | | | | | | | | | | | | | - 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
* More global initialization work done and proved in Coq.xleroy2011-03-131-1/+1
| | | | git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1603 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Initializers for global variables: compile-time evaluation of expressions ↵xleroy2011-03-121-0/+5
| | | | | | done in Coq (module Initializers), using the same primitives as those for CompCert C's semantics. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1602 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of branches/full-expr-4:xleroy2010-08-181-65/+103
| | | | | | | | | | | | | | | | | | | | | | - 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.xleroy2010-06-291-11/+11
| | | | | | | | | | | | | 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

* Reorganized the development, modularizing away machine-dependent parts.xleroy2008-12-301-0/+305
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
