* | Refine the type of function results in AST.signatureXavier Leroy2020-02-211-0/+8
|/ | | | | | | | | | Before it was "option typ". Now it is a proper inductive type that can also express small integer types (8/16-bit unsigned/signed integers). One benefit is that external functions get more precise types that control better their return values. As a consequence, the CompCert C type preservation property now holds unconditionally, without extra typing hypotheses on external functions.
* Resynchronize the LICENSE file and the license headers in individual files (#45)Xavier Leroy2018-01-051-0/+3
| | | | | | | | | | | Some files are dual-licensed (GPL + noncommercial license), as marked redundantly in the license headers of those files, and in the LICENSE file. OVer the years those two markings got inconsistent. This commit updates the LICENSE file and the license headers of some files so that they agree on which files are dual-licensed. Some build-related files were dual-licensed but some others were not. Fixed by dual-licensing configure, Makefile.menhir, extraction/extraction.v, */extractionMachdep.v Moved lib/Json* to backend/ because there is no need to dual-license those files, yet lib/* is dual-licensed. Plus: JsonAST did not really belong in lib/ anyway, as it depends on AST which is not in lib/
* New support for inserting ais-annotations.Bernhard Schommer2017-10-191-2/+2
| | | | | | | | | | | | The ais annotations can be inserted via the new ais variants of the builtin annotation. They mainly differe in that they have an address format specifier '%addr' which will be replaced by the adress in the binary. The implementation simply prints a label for the builtin call alongside a the text of the annotation as comment and inserts the annotation together as acii string in a separate section 'ais_annotations' and replaces the usages of the address format specifiers by the address of the label of the builtin call.
* Extend builtin arguments with a pointer addition operatorXavier Leroy2017-07-061-0/+3
| | | | | | This extension enables more addressing modes to be encoded as builtin arguments and used in conjunction with volatile memory accesses. Current status: x86 port only, the only new addressing mode handled is reg + offset.
* Merge pull request #93 from AbsInt/separate-compilationXavier Leroy2016-03-201-0/+1
|\ | | | | | | | | | | | | | | | | | | | | | | This pull request implements "approach A" to separate compilation in CompCert from the paper Lightweight verification of separate compilation by Jeehoon Kang, Yoonseung Kim, Chung-Kil Hur, Derek Dreyer, Viktor Vafeiadis, POPL 2016, pages 178-190 In a nutshell, semantic preservation is still stated and proved in terms of a whole C program and a whole assembly program. However, the whole C program can be the result of syntactic linking of several C compilation units, each unit being separated compiled by CompCert to produce assembly unit, and these assembly units being linked together to produce the whole assembly program. This way, the statement of semantic preservation and its proof now take into account the fact that each compilation unit is compiled separately, knowing only a fragment of the whole program (i.e. the current compilation unit) rather than the whole program.
| * Add support for EF_runtime externalsXavier Leroy2016-03-061-0/+1
| | | | | | | | Also: in Events, use Senv.equiv to state invariance wrt changes of global envs.
* | Print floating-point numbers with more digits in debug outputsXavier Leroy2016-03-151-2/+2
|/ | | | | | As suggested in GPR#84, use '%.15F' to force the printing of more significant digits. (The '%F' format previously used prints only 6.) This is enough to represent the FP number exactly most of the time (but not always). Once OCaml 4.03 is out and CompCert switches to this version of OCaml, we'll be able to use hexadecimal floats for printing.

* Use Coq strings instead of idents to name external and builtin functions.Xavier Leroy2015-10-111-5/+5
| | | | | | | | | | The AST.ident type represents source-level identifiers as unique positive numbers. However, the mapping identifiers <-> AST.ident differs between runs of CompCert on different source files. This is problematic when we need to produce or recognize external functions and builtin functions with fixed names, for example: * in $ARCH/Machregs.v to define the register conventions for builtin functions; * in the VST program logic from Princeton to treat thread primitives specially. So far, we used AST.ident_of_string to recover the ident associated with a string. However, this function is defined in OCaml and doesn't execute within Coq. This is a problem both for VST and for future executability of CompCert within Coq. This commit replaces "ident" by "string" in the arguments of EF_external, EF_builtin, EF_inline_asm, EF_annot, and EF_annot_val. This provides stable names for externals and builtins, as needed. For inline asm and annotations, it's a matter of taste, but using strings feels more natural. EF_debug keeps using idents, since some kinds of EF_debug annotations talk about program variables.
* Renaming {BA,BR}_longofwords -> {BA,BR}_splitlong.Xavier Leroy2015-08-221-4/+4
| | | | | | | | Use EF_debug instead of EF_annot for line number annotations. Introduce PrintAsmaux.print_debug_info (very incomplete). powerpc/Asmexpand: revise expand_memcpy_small.
* Refactoring of builtins and annotations in the back-end.Xavier Leroy2015-08-211-22/+26
| | | | | | | | | | | | | | | | | | | | | | | | Before, the back-end languages had distinct instructions - Iannot for annotations, taking structured expressions (annot_arg) as arguments, and producing no results' - Ibuiltin for other builtins, using simple pseudoregs/locations/registers as arguments and results. This branch enriches Ibuiltin instructions so that they take structured expressions (builtin_arg and builtin_res) as arguments and results. This way, - Annotations fit the general pattern of builtin functions, so Iannot instructions are removed. - EF_vload_global and EF_vstore_global become useless, as the same optimization can be achieved by EF_vload/vstore taking a structured argument of the "address of global" kind. - Better code can be generated for builtin_memcpy between stack locations, or volatile accesses to stack locations. Finally, this commit also introduces a new kind of external function, EF_debug, which is like EF_annot but produces no observable events. It will be used later to transport debug info through the back-end, without preventing optimizations.
