| * Test __builtin_isel.Xavier Leroy2015-09-131-0/+2
| |
* | Fixed a few bugs in the pre parser. In particular, the following codeJacques-Henri Jourdan2015-09-301-0/+0
|/ | | | | | | | | | | | | | | was not parsed correctly: typedef int a; int f() { for(int a; ;) if(1); a * x; } Additionnaly, I tried to add some comments in the pre-parser code, especially for the different hacks used to solve various conflicts.

| * Turn off copy optimization when returning a composite by reference.Xavier Leroy2015-07-081-0/+0
| | | | | | | | | | | | The copy optimization is not correct in case of overlap between destination and source. We would need to use an hypothetical __builtin_memmove_aligned that can cope with overlap to implement the copy at return of callee.
| * Fix issue with bit fields of type _BoolXavier Leroy2015-07-081-3/+3
| | | | | | | | | | | | cparser/Bitfields.ml: when assigning to a bit field of type _Bool, the right-hand side must be normalized to 0 or 1 via a cast to _Bool. test/regression/bitfields{1,9}.c: add corresponding test cases.
* | More portable test for fres and fsqrte.Xavier Leroy2015-07-081-2/+2
|/ | | | These instructions are approximate and produce different results on different processors. Just check the error bounds specified in the PPC ISA.
* Signedness issue in specification of subtraction between two pointers.Xavier Leroy2015-06-301-0/+2
|
* Extended inline asm: handle missing cases.Xavier Leroy2015-04-281-0/+10
| | | | | | Bitfields: better translation of initializers and compound literals; run this pass before unblocking. Transform.stmt: extend with ability to treat unblocked code. test/regression: more bitfield tests.
* Support va_arg for vararg arguments of composite (struct/union) types.Xavier Leroy2015-03-201-1/+3
| | | | ARM is done, IA32 and PowerPC remain to be updated.
* Improvements in the StructReturn transformation (ABI conformance for passing ↵Xavier Leroy2015-03-201-62/+86
| | | | | | | | composites). - Implement the "1/2/4/8" composite return policy, used by IA32/MacOS X and IA32/BSD. - Move the default passing conventions from Machine.ml to compcert.ini, making it easier to test the various conventions. - More comprehensive interoperability test in regression/interop1.c.
* More interoperability tests.Xavier Leroy2015-01-281-4/+8
|
* ABI compatibility for struct/union function arguments passed by value.Xavier Leroy2015-01-271-0/+62
| | | | | | | | | | The passing of struct/union arguments by value implemented in the verified part of CompCert is not compatible with the ARM, PowerPC and x86 ABI. Here we enrich the StructReturn source-to-source emulation pass so that it implements the calling conventions defined in these ABIs. Plus: for x86, implement the returning of struct/union results by value in a way compatible with the ABI.
* Merge branch 'named-structs'Xavier Leroy2015-01-231-2/+2
|\ | | | | | | | | | | | | | | | | | | | | | | | | - 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.
| * Add a type system for CompCert C and type-checking constructor functions.Xavier Leroy2014-12-311-2/+2
| | | | | | | | | | Use these constructor functions in C2C to rely less on the types produced by the unverified elaborator.
