Another thing to notice that nested functions require executable
stack. This is also another reason to get rid of them.

nouveau_array.c seems to be using nested functions which is
not supported by clang (or the EDG based compilers it seems),
the reduced testcase looks like this:
foo()
{
auto void f();
void f() {};
}
I talked to the clang developers and they don't plan to
support this GNU extension since (they say) it would be too
hard to support it in the parser. Clang website notes the
following about this issue (from
http://clang.llvm.org/docs/UsersManual.html#c_unimpl_gcc )

clang does not support nested functions; this is a complex
feature which is infrequently used, so it is unlikely to be
implemented anytime soon.

Is there any chance of removing such code from Mesa?
Would be nice to get a comment on this.
I imagine you're the first person to try to compile that driver with
clang because nobody else has mentioned this before.
I don't think anyone would object to the code being rewritten to avoid
nested functions. Is that something that you could do?
