The fold-vec-extract tests work fine on the development version of GCC 13 for
64-bit, but they are still failing if I run them on a BE system that supports
32-bit code generation.  It looks like the insn count may need to be adjusted
for 32-bit:

GCC 10.4 is being released, retargeting bugs to GCC 10.5.

Can you check why/whether this does not happen with GCC 11+?  What fixed it
there?

Ah, I see

testsuite: powerpc fold-vec and sse updates.

Recent code generation changes have affected the count of some
instructions.
This patch updates the instruction count for fold-vec-extract on P7 and P8.

Also, some of SSE emulation intrinsics only work on LE systems.

gcc/testsuite/ChangeLog:

* gcc.target/powerpc/fold-vec-extract-char.p7.c: Adjust addi count.

which adjusted it to 9 ... so the same thing happens there.  So it must be
fine for you.
