m64 2 test passes
m32 1 unsupported test
I looked in gcc/testsuite/gcc/gcc.log and found the following message
about the -m32
cc1: error: -m32 not supported in this configuration^M

So, next I tried removing the -mupper-regs-di option.
/* { dg-do run { target { powerpc*-*-* && { p9vector_hw } } } } */
/* { dg-skip-if "do not override -mcpu" { powerpc*-*-* } { "-mcpu=*" } {
"-mcpu=power9" } } */
/* { dg-options "-mcpu=power9 -O2 " } */
With the same results as above. Note, I am running on
perch.aus.stglabs.ibm.com which
is a Power 9 system. Is -m32 not supported on Power 9?
So it looks like we do not need the lp64 or -mupper-regs-di options as we get
the same results
either way.
