Subject: ia64.c (ia64_expand_tls_address): Add ORIG_OP1 argument.
X-Git-Tag: releases/gcc-4.2.0~5672
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b15b83fb3bf49df836c84730431b68d498082825;p=thirdparty%2Fgcc.git

ia64.c (ia64_expand_tls_address): Add ORIG_OP1 argument.

	* config/ia64/ia64.c (ia64_expand_tls_address): Add ORIG_OP1 argument.
	Move ADDEND_{HI,LO} computation into TLS_MODEL_INITIAL_EXEC case.
	(ia64_expand_move): Adjust caller.

	* gcc.dg/tls/opt-11.c: New test.
