------- Comment #4 from carrot at google dot com 2009-07-24 07:37 ------- Just as I've figured out HAVE_cc0 is disabled. And cse_condition_code_reg does nothing for thumb target.
I also found that the conditional branch instructions is always in the same insn pattern as the previous compare instructions. So I even wonder there is any way to express the optimized sequence (movs followed by bcc). Is there any other places that I should take a look? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40835
