* More prudent analysis of uninitialized const global variables.Xavier Leroy2015-01-091-3/+6
| | | | | | | In the presence of separate compilation and linking, an uninitialized const global variable may be initialized elsewhere with a pointer value, falsifying the points-to analysis. Report and fix by Chung-Kil Hur and Jeehoon Kang.
* In -g -S mode, annotate the generated asm file with the C source code in ↵Xavier Leroy2015-01-076-86/+243
| | | | | | comments. Refactor printing of .loc debug directives in backend/PrintAnnot.ml
* PR#19: there is no reason to reject an empty "switch" statement.Xavier Leroy2015-01-061-2/+0
|
* PR#16: give option rules precedence over file pattern rules.Xavier Leroy2015-01-033-31/+38
| | | | | | Plus: simplify handling of -help and --help. Plus: error on unrecognized "-xxx" options so that "-foo.c" is not treated as a source file.
* PR#14: recognize ".so" arguments as files to pass to the linker.Xavier Leroy2015-01-021-1/+2
|
* PR#15: vararg functions are not eligible for inlining.Xavier Leroy2015-01-021-1/+1
|
* Translation of wide string literals.Xavier Leroy2015-01-011-6/+57
| | | | | | | Closes PR#13. Also: give string literals type unsigned char [] or signed char [] depending on the machine configuration. (Instead of unsigned char [] before.)
* Wrong handling of block-local function declarations (again)Xavier Leroy2015-01-011-12/+7
| | | | | Reapply commit c3b615f875ed2cf8418453c79c4621d2dc61b0a0 which was overwritten by 2d32afc5daf16c75d1a34f2716c34ae2e1efcce4
* Revised type compatibility check w.r.t. handling of attributes.Xavier Leroy2015-01-014-49/+93
| | | | | | | We now distinguish 3 modes (instead of 2 previously) for attributes: 1- strict compatibility, 2- ignore top-level attrs, 3- ignore all attrs recursively. In strict mode, const/volatile/restrict attributes must be identical, but nonstandard attributes may vary. Also: ignore top-level attrs when comparing function argument types, like GCC/Clang do. Net result is fewer warnings and type-checking that is closer to GCC/Clang.
* PR#12: regression introduced in commit 2d32afcXavier Leroy2014-12-301-2/+0
|
* PR#6: fix handling of wchar_t and assignments from wide string literals.Xavier Leroy2014-12-305-9/+31
| | | | | | | | | | - cparser/Machine indicates whether wchar_t is signed or not (it is signed int in Linux and BSD, but unsigned short in Win32) - The type of a wide string literal is "wchar_t *" if the typedef "wchar_t" exists in the environment (e.g. after #include <stddef.h>). Only if wchar_t is not defined do we use the default from Machine. - Permit initialization of any integer array from a wide string literal, not just an array of wchar_t.
* PR#11: support sizeof(struct {...}) and _Alignof(struct {...})Xavier Leroy2014-12-301-25/+38
| | | | This is a partial fix because other cases of struct definitions within type-names are still not handled, e.g. (struct { ... } *) <expr>. However, error reporting was improved for these cases.

* Recognize more of GCC's alternate keywords (e.g. "__signed").Xavier Leroy2014-12-291-21/+24
| | | | | Based on the source of GCC 4.9.2. Plus: reordered keywords in alphabetic order to facilitate comparison.
* Support "asm volatile" (closes: PR#5).Xavier Leroy2014-12-292-1/+3
| | | | The CompCert back-end already treats "asm" inserts as "volatile" in GCC's sense (performing unpredictable side-effects), so no change is required outside of the parser.
