Sure,but we not seem to have "crc.w.d.w" dword asm in loongarch 32bit mode,now the whole file can only run in 64bit mode? Thanks.
Sorry. I have checked the manual and it turns out you & Yuli are correct: even though the narrower CRC instructions doesn't require GRLEN=64, they still *aren't* part of LA32 (LoongArch reference manual v1.10, Volume 1, Table 2-1). Counter-intuitive as it is, the original patch is correct nevertheless.
I'm going to amend my review shortly. -- WANG "xen0n" Xuerui Linux/LoongArch mailing list: https://lore.kernel.org/loongarch/
