Thanks so much for your info.
Here are test results on P7 AIX7.1. I tested all scalar-extract-sig-* and
scalar-insert-exp-* cases in
"testsuite/powerpc/bfp" fold. All compiling cases pass except those use
__ieee128. The runnable cases
fail as expected. p9vector is not supported on P7 servers.
So the __ieee128 blocks Binary floating-point on AIX?
Thanks
