             Bug #: 54427
           Summary: Expose more vector extensions
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: glisse@gcc.gnu.org


Hello,

for gcc's vector extension to be really useful, we need a way to access a large
enough subset of operations on vectors in a target-independent way. C exposes
comparisons (< <= > >= == !=) and shifts (<< >>), but C++ doesn't. Either these
operators should be implemented in the C++ front-end as well, or some builtins
should be provided with the same role (__builtin_vec_less?).

Progress :-)

Documentation update is needed.

Next useful one would be ?: so we can generate vec_cond_expr. See the OpenCL
specification for a list of what's missing.

Another useful thing would be to audit the optimization passes that don't
expect vectors and mishandle them...

This test is now failing on powerpc64-unknown-linux-gnu due to warning messages
being emitted for 32-bit.

FAIL: c-c++-common/torture/vector-compare-2.c  -O0  (test for excess errors)
FAIL: c-c++-common/torture/vector-compare-2.c  -O1  (test for excess errors)
...

This is due to the fact that in the old location the compile command included
-w which suppressed warnings, whereas the new location does not. The test can
be fixed for powerpc by adding the following line (as is present in
c-c++-common/vector-compare-2.c).

/* { dg-options "-mabi=altivec" { target { { powerpc*-*-linux* } && ilp32 } } }
*/

But it looks like this same test started failing on i686-pc-linux-gnu
(http://gcc.gnu.org/ml/gcc-testresults/2012-09/msg01842.html), guessing for the
same reason. Not sure if there's some similar type option that can be added for
that target or whether '-w' should just be added to the testcase.

Forgot to include the error message, which is causing the failures:

I was kind of expecting that (mentioned in the patch submission) but couldn't
see what I was changing by moving the test.

Ah, thanks a lot! I didn't realize there was an automatic -w in the old
location.

Yes, I think adding -w is the easiest solution (after all that's just reverting
to the old behavior). Otherwise the test could be changed to pass arguments by
pointer like the others, but I didn't dare do that in case it was specifically
testing passing by value.

I'll submit the -w ASAP, thanks again.

>From a front-end perspective, we are getting close. Some remaining items:
- port ?: to the C front-end (I don't know the maybe_const stuff)
- support &&, ||, !
- make sure everything works with constexpr
- there is another PR about having a way to call sqrt on a vector
- (big item) have a better interface than an attribute, something that can be
deduced in template contexts as easily as std::array<type,nelts>...

There is more work in the middle-end.

Another piece that would be nice:
scalar1 ? vector : scalar2

(we already perform the conversion from scalar2 to vector when the condition is
a vector)

Related PRs involving || and && for vectors: PR 57198 and PR 58845.
PR 58845 contains information about having a sequence point in the
gimplification of those operators.

most of the remaining ones are tracked in other PRs, and the rest should be as
this PR has become too long.
