GCC maintainers:
The Power ABI document lists a number of built-ins that it is supposed
to support. There are still some missing. This patch adds the built-in
support for the following built-ins:
vector bool char vec_cmpeq vector bool char vector bool char
vector bool int vec_cmpeq vector bool int vector bool int
vector bool long long vec_cmpeq vector bool long long vector bool long long
vector bool short vec_cmpeq vector bool short vector bool short
vector bool char vec_cmpne vector bool char vector bool char
vector bool int vec_cmpne vector bool int vector bool int
vector bool long long vec_cmpne vector bool long long vector bool long long
vector bool short vec_cmpne vector bool short vector bool short
Bootstrapped and tested on powerpc64le-unknown-linux-gnu with no
regressions.
Is this ok for trunk?

gcc/ChangeLog:
2016-11-15 Carl Love <c...@us.ibm.com>
* config/rs6000/rs6000-c.c : Add built-in support for vector compare
equal and vector compare not equal. The vector compares take two
arguments of type vector bool char, vector bool short, vector bool int,
vector bool long long with the same return type.
gcc/testsuite/ChangeLog:
2016-11-15 Carl Love <c...@us.ibm.com>
* gcc.target/powerpc/builtins-3.c : New file to test the new
built-ins for vecotr compare equal and vector compare not equal.
