From c81fc13e34621ae4506ffaae7d3b657aaeb17803 Mon Sep 17 00:00:00 2001 From: David Edelsohn Date: Tue, 28 Sep 1999 14:13:58 -0400 Subject: [PATCH] xcoffout.c (xcoffout_declare_function): Add documentation. * xcoffout.c (xcoffout_declare_function): Add documentation. * rs6000.c (num_insns_constant_wide): Use TARGET_POWERPC64 not TARGET_64BIT. Compare constant to -1, not bit pattern. (easy_fp_constant): Use TARGET_POWERPC64 not TARGET_64BIT. (expand_block_move): Allow 8 DImode loads for PowerPC64. Fix gen_movsi typos.
