re PR tree-optimization/44043 (sorry, unimplemented: inlining failed in call to 'dst_output': optimizing for size and code size would grow)

2010-05-09  Richard Guenther  <rguenther@suse.de>

	PR middle-end/44043
	* ipa-inline.c (estimate_function_body_sizes): Return after
	disregarding inline limits.

	* gcc.c-torture/compile/pr44043.c: New testcase.
