Objet : Rép : [cfe-commits] [PATCH] _has_feature support for new C1X features.

As clang start to implements C1X, it may be useful to extend __has_feature to support the new implemented features.
Here is a patch that add 'c_static_assert' and 'c_generic_selection', and a test case similar to the one used for c++0x.
This patch adds 'c_generic_selection', but I don't know the status of this feature. If it is not ready yet, this part should be commented.
Hi Jean-Daniel,
We already have __has_feature(generic_selections).
My bad, I missed it. I moved it next to "static_assert", so it would be easier to find what C1X extensions are already declared here. Prefixing C features with c_ is unprecedented (and it would of course
be a bad idea to rename the existing C features/extensions) so I think
that for the sake of consistency the C1X static assert feature should
just be called "static_assert".
Of course, it would definitively be better to keep it consistent. Also, C1X static assertions are supported as an extension in all
languages so the feature should not be predicated on the C1X language
option.
Here is a patch that simply add "static_assert" and declare it enabled unconditionally.
Is there someone to review (and apply) this minor change ?
