            Bug ID: 109118
           Summary: [13 Regression] gcc.dg/mla_1.c failed on target w/o
                    __Uint32x4_t support
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: haochen.jiang at intel dot com
  Target Milestone: ---

For target w/o __Uint32x4_t support, like i386, when run through the testsuite,
we will get error like this:

error: unknown type name '__Uint32x4_t'; did you mean '__uint128_t'

We can reproduce by:

make check RUNTESTFLAGS="dg.exp=gcc.dg/mla_1.c --target_board='unix{-m64\
-march=cascadelake,-m32\ -march=cascadelake,-m32,-m64}'"

It should be a simple fix. But I am not sure whether the testcase aims to test
on middle-end or aarch64 target specific.

If we want to test on middle-end, we might not use the type __Uint32x4_t in
testcase.

If it is a just aarch64 specific test, I suppose we can move the target
aarch64*-*-* to dg-do compile to skip for other backend.

Christina, what is your opinion?

    testsuite: move mla_1 test to aarch64 only [PR109118]

    I previously made the test generic, but there's no list
    of targets that support integer MLA, and so it's not
    really feasible for me to make this generic.

    As such I've moved it to be AArch64 only.

Thanks for the report, I decided to make this non-generic since I wouldn't know
which targets support integer MLA anyway.
