-==================== Branch work171-bugs, patch #320 ====================
-
-Do not add -mvsx when building or 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.
-
-With these patches, the float128 libgcc support is only built if the default
-compiler has VSX support. If somebody wanted to enable the glibc support for
-big endian, they would need to set the base cpu to power8 to enable building
the
-libgcc float128 libraries.
-
-In addition to the changes in libgcc, this patch also changes the GCC tests so
-that it will only test float128 if the default compiler enables the VSX
-instruction set. Otherwise all of the float128 tests will fail because the
-libgcc support is not available.
