commit b5f934bf571d51be98b4a4c91292132df22a00a5
Author: Michael Meissner <meiss...@linux.ibm.com>
Date: Fri Sep 13 03:50:23 2024 -0400
Do not add -mvsx when testing the float128 support.
Currently, we add -mvsx when building the float128 support in libgcc. This
allows us to build the float128 support on a big endian system where the
default cpu is power4. While the libgcc support can be built, given there
is
no glibc support for float128 available.
However, adding -mvsx and building the libgcc float128 support causes
problems
if you set the default cpu to something like a 7540, which does not have VSX
support. The assembler complains that when the code does a ".machine
7450", you
cannot use VSX instructions.
After patching libgcc to not build the float128 support unless the host can
support float128 normally, this patch changes the GCC tests so that it will
only
do the IEEE 128-bit tests if the default compiler enables the VSX
instruction
set by default. Otherwise all of the float128 tests will fail because the
libgcc support is not available.
In addition to not doing the float128 tests when the compiler does not
natively
support float128, this patch also removes adding -mvsx, -mfloat128, and
-mfloat128-hardware enable the support if the compiler did not natively
enable
it.
I built little endian compilers and there were no regressions.
I built big endian compilers with the --with-cpu=power5 configure option,
and I
verified that none of the float128 support functions are built.
I also built big endian compilers on a power9 with the --with-cpu=native
configure option, and I verified that the float128 support functions were
built, since the default compiler used the VSX instruction set.
I verified that on both sets of big endian builds, that all of the float128
tests were skipped, since there is no support for float128 in glibc and the
GCC
compiler does not enable float128 on those systems.
Can I check these patches into the trunk assuming the original bugzilla
author
says they fix the problem?

* gcc.target/powerpc/abs128-1.c: Remove adding -mvsx, -mfloat128,
and
-mfloat128-hardware options to float128 test. Add explicit checks
for
the float128 support, rather than just using VSX as a stand in, or
assuming we can silently enable VSX if the default is power4. For
pr99708.c, also use the correct spelling to disable the float128
tests.
