Subject: omp-low.c (lower_rec_input_clauses): Build correct address expressions.
X-Git-Tag: releases/gcc-4.5.0~6582
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ada39f0b23c61dd0c3acc45c73910b07c9fc03f3;p=thirdparty%2Fgcc.git

omp-low.c (lower_rec_input_clauses): Build correct address expressions.

2009-04-15  Richard Guenther  <rguenther@suse.de>

	* omp-low.c (lower_rec_input_clauses): Build correct address
	expressions.
	(expand_omp_for_generic): Fix multiplication type.
	* tree-loop-distribution.c (build_size_arg): Build a
	size_t argument.
	(generate_memset_zero): Fix types.
	* tree-profile.c (prepare_instrumented_value): Correctly
	widen a pointer.
