--- Comment #1 from irar at il dot ibm dot com 2007-02-22 07:58 --- Here is the ChangeLog entry for that patch: 2007-02-09 Richard Henderson <[EMAIL PROTECTED]> * config/i386/constraints.md (Ym): New constraint. * config/i386/i386.md (movsi_1): Change Y2 to Yi constraints. (movdi_1_rex64): Split sse and xmm general register moves from memory move alternatives. Use conditional register constraints. (movsf_1, movdf_integer): Likewise. (zero_extendsidi2_32, zero_extendsidi2_rex64): Likewise. (movdf_integer_rex64): New. (pushsf_rex64): Fix output constraints. * config/i386/sse.md (sse2_loadld): Split rm alternative, use Yi. (sse2_stored): Likewise. (sse2_storeq_rex64): New. * config/i386/i386.c (x86_inter_unit_moves): Enable for not amd and not generic. (ix86_secondary_memory_needed): Don't bypass TARGET_INTER_UNIT_MOVES for optimize_size. Remove SF/DFmode hack. Ira -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30921
