* 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

| | | | | | | | | | - Revised memory model with Max and Cur permissions, but without bounds - Constant propagation of 'const' globals - Function inlining at RTL level - (Unprovable) elimination of unreferenced static definitions git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@1899 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* powerpc/PrintAsm.ml arm/PrintAsm.ml: updated (no label elimination).Gravatar xleroy2011-05-08
| | | | | | | | | | 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
* 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
