| | | | | | | | | | | | | | | | | | - Alternate semantics for Clight where function parameters are temporaries, not variables - New pass SimplLocals that turns non-addressed local variables into temporaries - Simplified Csharpminor, Cshmgen and Cminorgen accordingly - SimplExpr starts its temporaries above variable names, therefoe Cminorgen no longer needs to encode variable names and temps names. - Simplified Cminor parser & printer, as well as Errors, accordingly. - New tool clightgen to produce Clight AST in Coq-parsable .v files. - Removed side condition "return type is void" on rules skip_seq in the semantics of CompCert C, Clight, C#minor, Cminor. - Adapted RTLgenproof accordingly (now uses a memory extension). git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2083 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
