            Bug ID: 29743
           Summary: FAIL: gdb.arch/powerpc-power10.exp: found:
                    pmxvbf16ger2 a4,vs0,vs1,0,0,0
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2

On powerpc64le, I see:
...
FAIL: gdb.arch/powerpc-power10.exp: found: pmxvbf16ger2 a4,vs0,vs1,0,0,0
...

I think this is a regression by commit 79e24d0a6c0 ("PowerPC: Add support for
RFC02653 - Dense Math Facility"), as noted here (
https://sourceware.org/pipermail/binutils/2022-November/124140.html ).

--- Comment #1 from Carl E Love <cel at us dot ibm.com> ---
Yes, it is a new failure due to the commit.  

The commit changed the names of the the MMA instructions. 

The mnemonics for the pmxvf16ger*, pmxvf32ger*,pmxvf64ger*, pmxvi4ger8*,
pmxvi8ger4*, pmxvi16ger2* instructions were officially changed to
pmdmxvf16ger*, pmdmxvf32ger*, pmdmxvf64ger*, pmdmxvi4ger8*, pmdmxvi8ger4*,
pmdmxvi16ger* respectively.  

The old mnemonics are still supported by the assembler as extended mnemonics. 
The disassembler generates the new mnemonics. 

A patch set has been posted to address the name change in this test as well as
the instruction names in the comments of various gdb source files.
