| | | | | | | | | | | | | | | | | | | | | | | | Instead of assuming name uniqueness for all definitions in the program, these variants only assume uniqueness for a particular name. Use this approach to weaken the hypotheses for match_program and transf_program_partial_augment.

| |\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

| * | | Delay reads from !Machine.config before it is properly initialized.Xavier Leroy2015-01-228-68/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several definitions in Cutil and elsewhere were accessing the default value of !Machine.config, before it is properly initialized in Driver. Delay evaluation of these definitions, and initialize Machine.config to nonsensical values so that lack of initialization is caught early (e.g. in Cutil.find_matching_*_kind). Also, following up on commit [3b8a094], don't use "wchar_t" typedef to type wide string literals, even if this typedef is in scope. The risk here is to hide an inconsistency between "wchar_t"'s definition in standard headers and CompCert's built-in definition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is achieved by declaring these functions in C2C.ml, then re-checking their declarations in the global environment during the Selection pass. In passing, the "hf" parameter for SelectLong functions was removed and replaced by fixed identifiers corresponding to the actual names of the helper functions.

* | | Wrong handling of block-local function declarations (again)Xavier Leroy2015-01-011-12/+7

* | | 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.
