I'm sorry you see this as a matter of respect.  I didn't see it that
way at all.  Segher disagreed with your review, and gave sufficient
technical reason for me to commit the patch.

I am not going to do as you demand.  Those tests are clearly
commented as "VSX Linux 64-bit" tests.  Ignoring that comment and
changing them to make them run for AIX and Darwin plainly requires
that I test those changes, which often results in significant effort
building cross-compilers.

If you wish them to run for AIX targets then that is your job as an
AIX maintainer.  Don't expect me to do the work.

Incidentally, this is the result of your recent commit 122f0db2793 on
powerpc64-linux biarch.
+FAIL: gcc.target/powerpc/signbit-1.c scan-assembler-not stxvd2x
+FAIL: gcc.target/powerpc/signbit-1.c scan-assembler-times mfvsrd 3
+FAIL: gcc.target/powerpc/signbit-1.c scan-assembler-times srdi 3
+FAIL: gcc.target/powerpc/signbit-2.c scan-assembler-times ld 1
+FAIL: gcc.target/powerpc/signbit-2.c scan-assembler-times srdi 1

I'm not complaining about that, or demanding that you fix those fails;
In fact I'm in the middle of fixing them.  But they do quite perfectly
illustrate that tweaking the testsuite is never simple.
