When I fixed various tests in
<http://gcc.gnu.org/ml/gcc-patches/2014-03/msg01662.html> for failures
with --with-arch=bdver3, I missed that a so-configured compiler still
defaults to -mtune=generic. If you override that as well with
--with-cpu=bdver3, further failures appear, and this patch fixes some
of them.
Most of these changes add -mno-prefer-avx128 to AVX tests not
expecting a -mprefer-avx128 default. In addition, some tests have
-mtune=generic added where the behavior tested for depends on some
tuning parameter that I identified: X86_TUNE_EXT_80387_CONSTANTS or
X86_TUNE_SSE_LOAD0_BY_PXOR.
Tested x86_64-linux-gnu. OK to commit?
There are other failures this patch does not resolve in a
--with-arch=bdver3 --with-cpu=bdver3 configuration. Some of these are
AVX tests whose failures are not resolved by adding -mno-prefer-avx128
(and so this patch does not add -mno-prefer-avx128 to those tests);
others may be cases where -mtune=generic is appropriate but I haven't
identified the specific tuning parameter that shows code generation
differences depending on tuning are correct and so a -mtune= option
should be used.
