* Added support for quoting for diab backend.Bernhard Schommer2016-07-214-2/+21
| | | | | | The diab data compiler has different quoting conventions compared to the gnu tools. Bug 18308.
* Added simplified reader and printer for gnu @filesBernhard Schommer2016-07-2011-145/+140
| | | | | | | | The functions expandargv and writeargv resemble the functions from the libiberity that are used by the gnu tools. Additionaly a new configuration is added in order to determine which kind of response files are supported for calls to other tools. Bug 18308
* Merged responfile function into command.Bernhard Schommer2016-07-195-49/+33
| | | | | | Command now decides whether to use a responsefile or call the external command directly. Bug 18004
* Added heuristic for passing arg via responsefiles.Bernhard Schommer2016-07-127-31/+51
| | | | | | | Since gnu make and other tools under windows seem to have a limit of around 8000 bytes per command line the arguments should be passed via responsefiles instead. Bug 18308

* Added function to write responsefiles.Bernhard Schommer2016-07-111-0/+24
| | | | | | The arguments are written in the responsefile separated by whitespace. If the argument itself contains a whitespace it is quoted. Bug 18308

| * | Unwanted partial constant propagation in 64-bit integer arguments to builtinsXavier Leroy2016-07-088-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here are two examples that cause an internal error in Asmexpand.ml: volatile long long x; void f(unsigned int i) { x = i; } unsigned g(unsigned i) { return __builtin_clzll(i); } The argument "i" to builtin volatile store or __builtin_clzll is turned into a BA_splitlong(BA_int 0, BA <variable i>), which Asmexpand.ml doesn't know how to handle. The fix (in AST.builtin_arg_ok) is to prevent this 'optimization' for all builtins except those of the "OK_all" kind, i.e. __builtin_annot. Regression tests were added and tested on IA32. Need to retest on ARM and PowerPC.

|/ | | | | | | | Commandline can now be passed in a file specifed with @file on the Commandline. The quoting convention is similar to the one used by gcc, etc. Options are separated by whitespaces and options with whitespaecs need to be quoted. Bug 18303

| |/ | | | | | | As suggested by Lennart Beringer, this commits strengthens memory injections and extensions so as to guarantee that the permissions of existing memory locations are not increased by the injection/extension. The only increase of permissions permitted is empty locations in the source memory state of the injection/extension being mapped to nonempty locations.

| | | | | | | | - Values: "rol" and "ror" are defined even if their second argument is not in the [0,31] range (for consistency with "rolm" and because the semantics is definitely well defined in this case). - NeedDomain: more precise analysis of "rol" and "rolm", could benefit the PowerPC port.

| * Introduce register pairs to describe calling conventions more preciselyXavier Leroy2016-05-1732-894/+888
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit changes the loc_arguments and loc_result functions that describe calling conventions so that each argument/result can be mapped either to a single location or (in the case of a 64-bit integer) to a pair of two 32-bit locations. In the current CompCert, all arguments/results of type Tlong are systematically split in two 32-bit halves. We will need to change this in the future to support 64-bit processors. The alternative approach implemented by this commit enables the loc_arguments and loc_result functions to describe precisely which arguments need splitting. Eventually, the remainder of CompCert should not assume anything about splitting 64-bit types in two halves. Summary of changes: - AST: introduce the type "rpair A" of register pairs - Conventions1, Conventions: use it when describing calling conventions - LTL, Linear, Mach, Asm: honor the new calling conventions when observing external calls - Events: suppress external_call', no longer useful - All passes from Allocation to Asmgen: adapt accordingly.
