llvm-stress crash
Hi,
Using llvm-stress, I got a crash after Post-RA pseudo expansion, with
machine verifier.
A 128 bit register
%vreg233:subreg_l32<def,read-undef> = LLCRMux %vreg119;
GR128Bit:%vreg233 GRX32Bit:%vreg119
gets spilled:
%vreg265:subreg_l32<def,read-undef> = LLCRMux %vreg119;
GR128Bit:%vreg265 GRX32Bit:%vreg119
ST128 %vreg265, <fi#10>, 0, %noreg; mem:ST16[FixedStack10](align=8)
GR128Bit:%vreg265
-> regal...
