[cfe-commits] Bug 11709 Fix: va_list on ARM is not following AAPCS 7.1.4

Hi Anton,

Attached is the fix for the issue and a test case for that.
The cause is that the original BuildVAArgExpr missed the case of a record type va_list.  I fixed that issue and I also refactored my original va_list construction code by removing the redundant call of creating RecordDecl.

Please review it.
Sorry for the inconvenience.

I'm seeing the copy-ctor assertion every time someone is using __builtin_va_arg. Will you please fix and add the testcase for it as well?

Something like:

__builtin_va_list ap;
foo = __builtin_va_arg(ap, int)
