[LLVMdev] RegisterCoalescing Pass seems to ignore part of CFG.

It seems the PhiElim is working correctly, the output of --debug-only=regalloc
shows that %vreg48 is a phi-join register, and intervals looks correct to me :

[LLVMdev] RegisterCoalescing Pass seems to ignore part of CFG.

When examining the debug output of regalloc, it seems that joining 32bits reg
also joins 128 parent reg.

If I look at the :
%vreg34<def> = COPY %vreg6:sel_y; R600_Reg32:%vreg34 R600_Reg128:%vreg6

instructions ; it gets joined to :
928B%vreg34<def> = COPY %vreg48:sel_y; 

when vreg6 and vreg48 are joined. It's right.

But joining the following copy 

912B%vreg32:sel_x<def,read-undef> = COPY %vreg48:sel_x;
R600_Reg128:%vreg32,%vreg48

updates it to 
928B%vreg34<def> = COPY %vreg32:sel_y; R600_Reg32:%vreg34
R600_Reg128:%vreg32

which is wrong. vreg32:sel_y is undef.

Regards,
Vincent

Well, that seems correct to me. Following the code and debug output, the 
joining is going from vreg6->vreg48->vreg32. vreg6 is defined at BB0, so 
it will be vreg32 and its sel_y subreg also.
Try to run the verifier with -verify-coalescing.
If you have implemented the hooks for the coalescer in your 
TargetRegisterInfo you can also try to disable them to verify the 
implementation. Hope this helps to spot the problem.
