[PATCH] D95588: [RISCV] Implement the MC layer support of P extension

[Jim Lin via Phabricator via cfe-commits]

Jim updated this revision to Diff 372052.
Jim added a comment.

Update to the newest P spec 0.96
https://github.com/riscv/riscv-p-spec/blob/master/P-ext-proposal.adoc#revision-history

1. Merger Zprvsfextra (sub-extension for RV64 only) into Zpn So, RV32 and RV64 have the same sub-extension combination policy. P = Zpn + Zpsfoperand @jrtc27's concern is not existed now.
2. Removed CLO* instructions.
3. Fix incorrect testcases.

1. CHECK: attribute      5, "rv64i2p0_p0p93_zpn0p96_zprvsfextra0p96_zpsfoperand0p96"
