--- Comment #5 from Carl Love <carll at gcc dot gnu.org> ---
There are a couple of issues with the test case in the attachment. For example
one of the tests is:
static inline vui64_t
vec_vsldbi_64 (vui64_t vra, vui64_t vrb, const unsigned int shb)
{
return vec_sldb (vra, vrb, shb);
}
When I tried to compile it, it seemed to compile. However if I take off the
static inline, then I get an error about in compatible arguments. The built-in
requires an explicit integer be based in the third argument. The following
worked for me:
static inline vui64_t
vec_vsldbi_64 (vui64_t vra, vui64_t vrb, const unsigned int shb)
{
return vec_sldb (vra, vrb, 1);
}
The compiler/assembler needs an explicit value for the third argument as it has
to generate the instruction with the immediate shift value as part of the
instruction. Hence a variable for the third argument will not work.
Agreed that the __int128 arguments can and should be supported. Patch to add
that support is in progress but will require getting the LLVM/OpenXL team to
agree to adding the __128int variants as well.
