| * Interpreter produces more detailed trace, including name of semantic rules used.Xavier Leroy2015-02-081-95/+61
| | | | | | | | | | | | Cexec: record names of rules used in every reduction. Interp: print these rule names in -trace mode. Also: simplified the exploration in "-all" mode; give unique names to states. Csem: fix name of reduction rule "red_call".
| * Merge branch 'named-structs'Xavier Leroy2015-01-232-12/+14
| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Switch CompCert C / Clight AST of composite types (structs and unions) from a structural representation to a nominal representation, closer to concrete syntax. - This avoids algorithmic inefficiencies due to the structural representation. - Closes PR#4. - Smallstep: make small-step semantics more polymorphic in the type of the global environment. - Globalenvs: introduce Senv.t (symbol environments) as a restricted view on Genv.t (full global environments). - Events, Smallstep: use Senv instead of Genv to talk about global names.

| | * Introduce symbol environments (type Senv.t) as a restricted view on global ↵Xavier Leroy2014-11-261-1/+1
| | | | | | | | | | | | environments (type Genv.t). Use symbol environments instead of global environments for external functions (module Events).
| * | PR#16: give option rules precedence over file pattern rules.Xavier Leroy2015-01-033-31/+38
| | | | | | | | | | | | | | | | | | Plus: simplify handling of -help and --help. Plus: error on unrecognized "-xxx" options so that "-foo.c" is not treated as a source file.
| * | PR#14: recognize ".so" arguments as files to pass to the linker.Xavier Leroy2015-01-021-1/+2

|/ | | | directory. Use Sys.executable_name instead of Sys.argv.(0).
* Verification of the Unusedglob pass (removal of unreferenced static global ↵Xavier Leroy2014-11-242-2/+9
| | | | definitions). Assorted changes to ia32/Op.v. PowerPC and ARM need updating.
* Add Genv.public_symbol operation.Xavier Leroy2014-11-241-1/+21
| | | | | Restrict pointer event values to public global names. Update proofs accordingly. PowerPC and ARM need updating.
* Record public global definitions via field "prog_public" in AST.program.Xavier Leroy2014-11-241-1/+2
| | | | For the moment, this field is ignored.
* Add flags to control individual optimization passes + flag -O0 for turning ↵Xavier Leroy2014-11-164-37/+116

* Revised parsing of command-line arguments (in preparation for adding more).Xavier Leroy2014-11-163-118/+250
| | | | | | Honor "ccomp -E foo.h" for GCC compatibility. Accept .o.ext files as object files for GCC compatibility. Fixed and improved handling of Cminor source files.
* Revised translation of '&&' and '||' to Clight.Xavier Leroy2014-10-131-1/+1
| | | | | | | | | | | The previous translation (in SimplExpr) produced references to the same temporary variable with two different types (bool and int), which is not nice if we want to typecheck the generated Clight. The new translation avoids this and also gets rid of the double cast to bool then to int. The trick is to change Eparen (in CompCert C expressions) to take two types: the type to which the argument must be converted, and the type with which the resulting expression is seen.
* Removed environment variable for the stdlib_path and added a new variable ↵Bernhard Schommer2014-10-063-20/+20
| | | | for the configuration file.
* Change the way the tools like the linker, assembler, etc. are specified by ↵Bernhard Schommer2014-09-301-0/+86
| | | | including an .ini file parser. The .ini file is generated in the Makefile instead of the Configuration.ml file and parsed on start.

* Merge of "newspilling" branch:xleroy2014-07-231-1/+1
| | | | | | | | | | | | | | | - Support single-precision floats as first-class values - Introduce chunks Many32, Many64 and types Tany32, Tany64 to support saving and restoring registers without knowing the exact types (int/single/float) of their contents, just their sizes. - Memory model: generalize the opaque encoding of pointers to apply to any value, not just pointers, if chunks Many32/Many64 are selected. - More properties of FP arithmetic proved. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2537 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e

* Merge of branch linear-typing:xleroy2014-04-063-22/+78
| | | | | | | | | | | | | | | | | | | | | | | 1) Revised division of labor between RTLtyping and Lineartyping: - RTLtyping no longer keeps track of single-precision floats, switches from subtype-based inference to unification-based inference. - Unityping: new library for unification-based inference. - Locations: don't normalize at assignment in a stack slot - Allocation, Allocproof: simplify accordingly. - Lineartyping: add inference of locations that contain a single-precision float. - Stackingproof: adapted accordingly. This addresses a defect report whereas RTLtyping was rejecting code that used a RTL pseudoreg to hold both double- and single-precision floats (see test/regression/singlefloats.c). This corresponds to commits 2435+2436 plus improvements in Lineartyping. 2) Add -dtimings option to measure compilation times. Moved call to C parser from Elab to Parse, to make it easier to measure parsing time independently of elaboration time. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2449 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
