* Delay reads from !Machine.config before it is properly initialized.Xavier Leroy2015-01-221-6/+36
| | | | | | | | | | | | | 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.
* PR#6: fix handling of wchar_t and assignments from wide string literals.Xavier Leroy2014-12-301-3/+11
| | | | | | | | | | - 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.
