* | [PowerPC] Spill CR LT bits on P9 using setb | Amy Kwan | 2019-11-24 | 1 | -0/+56 |
This patch aims to spill CR[0-7]LT bits on POWER9 using the setb instruction. The sequence on P9 to spill these bits will be: setb %reg, %CRREG stw %reg, $FI Instead of the typical sequence: mfocrf %reg, %CRREG rlwinm %reg1, %reg, $SH, 0, 0 stw %reg1, $FI Differential Revision: https://reviews.llvm.org/D68443 |
