[packages/gcc.git] / gcc32-c++-pretty_function.patch

2002-05-24  Jakub Jelinek  <jakub@redhat.com>

	PR c++/6794
	* decl.c (cp_make_fname_decl): If outside of function, emit
	the variable immediately.
	* call.c (build_call): Avoid crashing when noreturn function
	is called outside of function context.

	* g++.dg/ext/pretty1.C: New test.
	* g++.dg/ext/pretty2.C: New test.
