* | Added new Mingw Printer. Currently the only difference to the Cygwin printer ↵Bernhard Schommer2015-02-101-13/+55
|/ | | | is that every symbol must start with an "_".
* In -g -S mode, annotate the generated asm file with the C source code in ↵Xavier Leroy2015-01-071-22/+9
| | | | | | comments. Refactor printing of .loc debug directives in backend/PrintAnnot.ml
* Clean up support for common symbols. Uninitialized "const" symbols can be ↵Xavier Leroy2014-12-171-14/+44

* Update the IA32/MacOS X port.Xavier Leroy2014-12-111-4/+6
| | | | | | - Prefix symbols with _ - Print indirect symbol definitions - Suppress __asm() macros in system header files
* Prevent constant propagation on Oindirectsymbol addresses.Xavier Leroy2014-12-111-2/+11
| | | | | (Otherwise they are turned into Oaddrsymbol or global addressing modes, causing linking issues on MacOS X.)
* Verification of the Unusedglob pass (removal of unreferenced static global ↵Xavier Leroy2014-11-242-67/+44

| | | | | Restrict pointer event values to public global names. Update proofs accordingly. PowerPC and ARM need updating.

| | | | | | | | | The only platform where we have two variants is ARM, and it's easier to share the callling convention code between the two than to maintain both variants separately. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2540 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e
* Merge of "newspilling" branch:xleroy2014-07-2317-324/+698
| | | | | | | | | | | | | | | - 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
