[LLVMdev] RegisterCoalescing Pass seems to ignore part of CFG.
Hi,
I don't know if my llvm ir code is faulty, or if I spot a bug in the RegisterCoalescing Pass, so I'm posting my issue on the ML. Shader and print-before-all dump are given below.
The interessing part is the vreg6/vreg48 reduction : before RegCoalescing, the machine code is :
// BEFORE LOOP
... Some COPYs....
