* | | 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#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.

* | | 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.

* Revised translation of '&&' and '||' to Clight.Xavier Leroy2014-10-1311-124/+109
| | | | | | | | | | | The previous translation (in SimplExpr) produced references to the same temporary variable with two different types (bool and int), which is not nice if we want to typecheck the generated Clight. The new translation avoids this and also gets rid of the double cast to bool then to int. The trick is to change Eparen (in CompCert C expressions) to take two types: the type to which the argument must be converted, and the type with which the resulting expression is seen.
