[PATCH, rs6000] Enable block compare expand on P9 with m32 and mpowerpc64

2024-01-11 Thread HAO CHEN GUI
Hi, On P9 "setb" is used to set the result of block compare. So it works with m32 and mpowerpc64. On P8, carry bit is used. So it can't work with m32 and mpowerpc64. This patch enables block compare expand for m32 and mpowerpc64 on P9. Bootstrapped and tested on x86 and powerpc64-linux BE and
