-==================== Branch work171-bugs, patch #331 ====================
-
-Do not add -mvsx when testing the float128 support.
-
-In the past, we would add -mvsx when building the float128 support in libgcc.
-This allowed 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.
-
-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.
