- Subject: [PATCH] [C++] Fix C++/13507
This patch fixes PR C++/13507. The problem is that the type for the
decl is shared with other decls. I made sure that I did not brake the
other PR which the patches which causes this work.
This should get the right semantics which are needed for c++ and
builtins.
Bootstrapped on powerpc-apple-darwin7.2.0 with no regressions.
Ok for the mainline and 3.3?
ChangeLog:
* decl.c: When setting the type of an anticipated
declaration, merge the existing type attributes
and copy TYPE_RAISES_EXCEPTIONS instead of using
the new type.
