--- Comment #23 from Michael Meissner ---
This is one of those things where there is no right answer in part because we
need other things to flesh out the support.
The reason -mvsx was used is we need the VSX registers to build the IEEE
128-bit

When I wrote the VSX support many years ago, I intended that -mvsx enable all
of ISA 2.06, which includes ISA 2.05, etc.
My intentions were there 2 options for power7, one is the base ISA 2.07 support

Sidenote: Interestingly GCC 14 builds fine with -mcpu=970 -mtune=970 despite
the PowerPC G5 (aka. 970, POWER4+) is before ISA 2.06 and not being able to use
-mvsx either.
I used Gentoo snapshot gcc-14.0.1_pre2

I tried to build older snapshots as well (back to 20231119) and it seems this
assembler error still occurs back to there so I was wrong about this being a
new thing.

So t-float128 has this line:
# Build the emulator without ISA 3.0 hardware support.
FP128_CFLAGS_SW = -Wno-type-limits -mvsx -mfloat128 \

Which gets added to some of the libgcc object files whi

oops, I meant --enable-checking rather than --checking.

I think this is related to r10-580-ge154242724b084 and this failure is expected
and a use error.
With it applied, we don't always pass -many to assembler with CHECKING_P
enabled. Actually compilers (gcc-13, gcc

I've managed to get the args down to the following as well:
gcc -mcpu=7450 -O0 -ftree-coalesce-vars -mvsx -c _kf_to_sd.i
-mcpu=7450 seems to be (one of) the root causes along with
-ftree-coalesce-vars.
