Chris Lattner c970f062e0 If LSR went through a lot of trouble to put constants (e.g. the addr of a global ... in a specific BB, don't undo this!). This allows us to compile CodeGen/X86/loop-hoist.ll into: _foo: xorl %eax, %eax *** movl L_Arr$non_lazy_ptr, %ecx movl 4(%esp), %edx LBB1_1: #cond_true movl %eax, (%ecx,%eax,4) incl %eax cmpl %edx, %eax jne LBB1_1 #cond_true LBB1_2: #return ret instead of: _foo: xorl %eax, %eax movl 4(%esp), %ecx LBB1_1: #cond_true *** movl L_Arr$non_lazy_ptr, %edx movl %eax, (%edx,%eax,4) incl %eax cmpl %ecx, %eax jne LBB1_1 #cond_true LBB1_2: #return ret This was noticed in 464.h264ref. This doesn't usually affect PPC, but strikes X86 all the time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@30290 91177308-0d34-0410-b5e6-96231b3b80d8		2006-09-13 06:02:42 +00:00
