------- Comment #13 from pinskia at gcc dot gnu dot org 2006-01-18 20:26 ------- Hmm, we actually produce better code on the mainline for my example in comment #2: _xtermEnvEncoding1: movl _result.1525, %edx movl $2, %eax pushl %ebp movl %esp, %ebp popl %ebp testl %edx, %edx cmovne _result.1525, %eax movl %eax, _result.1525 ret
But that is does not fix the problem in comment #0. Load PRE on the tree level is not working because this is not an indirect reference to the variable. That is a known issue too. -- pinskia at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Component|target |middle-end GCC target triplet|i686-pc-linux.-gnu |i686-*-* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=23488
