The first patch in the vector pair series was previous posted. This patch
needs that first patch. The first patch implemented the basic modes, and it
allows for initialization of the modes. In addition, I added some
optimizations for extracting and setting fields within the vector pair.
The second patch in the vector pair series implemented floating point support.
The third patch in the vector pair series implemented integer point support.
This fourth patch provide new tests to the test suite.
When I test a saxpy type loop (a[i] += (b[i] * c[i])), I generally see a 10%
improvement over either auto-factorization, or just using the vector types.
I have tested these patches on a little endian power10 system. With
-vector-size-32 disabled by default, there are no regressions in the
test suite.
I have also built and run the tests on both little endian power 9 and big
endian 9 power systems, and there are no regressions. Can I check these
patches into the master branch?
