2008-01-05Chris and Evan noticed that this check was compleatly fubared. I wasBill Wendling
checking that there was a from a global instead of a load from the stub for a global, which is the one that's safe to hoist. Consider this program: volatile char G[100]; int B(char *F, int N) { for (; N > 0; --N) F[N] = G[N]; } In static mode, we shouldn't be hoisting the load from G: $ llc -relocation-model=static -o - a.bc -march=x86 -machine-licm LBB1_1: # bb.preheader leal -1(%eax), %edx testl %edx, %edx movl $1, %edx cmovns %eax, %edx xorl %esi, %esi LBB1_2: # bb movb _G(%eax), %bl movb %bl, (%ecx,%eax) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45626 91177308-0d34-0410-b5e6-96231b3b80d8
