* Formatted json printing.Bernhard Schommer2017-06-281-8/+23
| | | | | | | | | Instead of just dumping the json output it is now a little bit formatted for better reading. Furthermore the AsmToJson function for the non powerpc targets now prints the json value "null" sucht that the resulting json file is valid json.
* Added a little bit more compilation info to sdump.Bernhard Schommer2017-06-261-2/+9
| | | | | | The additional compilation information contains the file, command line (after @-file expansion) and the current working directory. Bug 21690
* RISC-V port and assorted changesXavier Leroy2017-04-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commits adds code generation for the RISC-V architecture, both in 32- and 64-bit modes. The generated code was lightly tested using the simulator and cross-binutils from https://riscv.org/software-tools/ This port required the following additional changes: - Integers: More properties about shrx - SelectOp: now provides smart constructors for mulhs and mulhu - SelectDiv, 32-bit integer division and modulus: implement constant propagation, use the new smart constructors mulhs and mulhu. - Runtime library: if no asm implementation is provided, run the reference C implementation through CompCert. Since CompCert rejects the definitions of names of special functions such as __i64_shl, the reference implementation now uses "i64_" names, e.g. "i64_shl", and a renaming "i64_ -> __i64_" is performed over the generated assembly file, before assembling and building the runtime library. - test/: add SIMU make variable to run tests through a simulator - test/regression/alignas.c: make sure _Alignas and _Alignof are not #define'd by C headers commit da14495c01cf4f66a928c2feff5c53f09bde837f Author: Xavier Leroy <xavier.leroy@inria.fr> Date: Thu Apr 13 17:36:10 2017 +0200 RISC-V port, continued Now working on Asmgen. commit 36f36eb3a5abfbb8805960443d087b6a83e86005 Author: Xavier Leroy <xavier.leroy@inria.fr> Date: Wed Apr 12 17:26:39 2017 +0200 RISC-V port, first steps This port is based on Prashanth Mundkur's experimental RV32 port and brings it up to date with CompCert, and adds 64-bit support (RV64). Work in progress.

|\ | | | | | | | | | | Remove CompCert's ability to parse and compile source files written in Cminor This facility is no longer used (as far as we know) and is painful to maintain.

* Refactor the classification of attributesXavier Leroy2017-02-031-0/+1
| | | | | | | | | | | | | | | Introduce Cutil.class_of_attribute to return the class of the given attribute: one among Attr_type attribute related to types (e.g. "aligned") Attr_struct attribute related to struct/union/enum types (e.g. "packed") Attr_function attribute related to function types (e.g. "noreturn") Attr_name attribute related to variable and function declarations (e.g. "section") Attr_unknown attribute was not declared Cutil.declare_attribute is used to associate a class to a custom attribute. Standard attributes (const, volatile, _Alignas, etc) are Attr_type. cfronted/C2C.ml: declare the few attributes that CompCert honors currently. cparser/GCC.ml: a bigger list of attributes taken from GCC, for reference only.

* Use quoted strings.Bernhard Schommer2017-01-181-74/+79
| | | | | | Instead of escaping all newlines etc for the help options use quoted strings. Bug 19872
* Added backtrace handler.Bernhard Schommer2017-01-171-0/+2
| | | | | | | | If CompCert crashes because of an uncaught exception the exception is caught toplevel and the backtrace is printed plus an additional message to include the backtrace in a support request, if buildnr and tag are available. Bug 20681.

|\ | | | | | | Support for 64-bit target processors + support for x86 in 64-bit mode
| * Make Archi.ptr64 always computable, and reorganize files accordingly: ia32 ↵Xavier Leroy2016-10-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | -> x86/x86_32/x86_64 Having Archi.ptr64 as an opaque Parameter that is determined at run-time depending on compcert.ini is problematic for applications such as VST where functions such as Ctypes.sizeof must compute within Coq. This commit introduces two versions of the Archi.v file, one for x86 32 bits (with ptr64 := false), one for x86 64 bits (with ptr64 := true). Unlike previous approaches, no other file is duplicated between these two variants of x86. While we are at it, I renamed "ia32" into "x86" everywhere. "ia32" is Intel speak for the 32-bit architecture. It is not a good name to describe both the 32 and 64 bit architectures. Finally, .depend is no longer under version control and is regenerated when the target architecture changes. That's because the location of Archi.v differs between the ports that have 32/64 bit variants (x86 so far) and the ports that have only one bitsize (ARM and PowerPC so far).
| * Support for 64-bit architectures: generic supportXavier Leroy2016-10-011-3/+6
| | | | | | | | | | | | | | | | | | | | | | - Introduce Archi.ptr64 parameter. - Define module Ptrofs of integers as wide as a pointer (64 if Archi.ptr64, 32 otherwise). - Use Ptrofs.int as the offset type for Vptr values and anywhere pointer offsets are manipulated. - Modify Val operations that handle pointers (e.g. Val.add, Val.sub, Val.cmpu) so that in 64-bit pointer mode it is the "long" operation (e.g. Val.addl, Val.subl, Val.cmplu) that handles pointers. - Update the memory model accordingly. - Modify C operations that handle pointers (e.g. addition, subtraction, comparisons) accordingly. - Make it possible to turn off the splitting of 64-bit integers into pairs of 32-bit integers. - Update the compiler front-end and back-end accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now each warning either has a name and can be turned on/off, made into an error,etc. or is a warning that always will be triggered. The message of the warnings are similar to the ones emited by gcc/clang and all fit into one line. Furthermore the diagnostics are now colored if colored output is available. Bug 18004
