Bug ID: 23419
Summary: Missing/Wrong Extended Mnemonics for POWER9 mt/fspr
Product: binutils
Version: 2.32 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org

Target Milestone: ---

Patch
The Power ISA 3.0B suggests having extended mnemonics for moving from and to
the perfomance count registers instead of using mt/fspr, so for example `mfspr
ra, 771` becomes `mfupmc1 ra` or `mfpmc1 ra` (see page 972 in the isa).
Attached is my humble try at a patch. (I couldn't make `make check` work, I
hope it works).
