It is highly speculative at this point, but it adds maintenance burden.
2023-01-14adding pseudo_ops for shift-ops where the mnemonics remain the sameNeel Gala1-0/+3
2023-01-12Fix backwards incompatibility introduced by RV128 opcodes in #112Andrew Waterman1-4/+3
Adding RV128 shift opcodes changed what metadata we emit for SLLI, SRLI, and SRAI. Thus, downstream tooling that relies on these to connote the RV64 variants of these instructions is semantically affected. Fix by reverting SLLI etc. to being the RV64 variants.
2023-01-12Rename RV128 shamt to shamtqAndrew Waterman1-3/+3
This will reduce the chance that people pick the wrong shamt width.
