Why must be 'series of rlwimi'? Why don't we just expand it following what ISA describes and let legalizer generates code sequence under 32-bit mode? ``` n ← sh5 || sh0:4 r ← ROTL64((RS), n) b ← mb5 || mb0:4 m ← MASK(b, ¬n) RA ← r&m | (RA) & ¬m ``` https://github.com/llvm/llvm-project/pull/86783 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
