Bug ID: 65526
Summary: testsuite checks for arm vectorization support on
non-arm targets
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: msebor at gcc dot gnu.org

Patch to avoid unnecessary testsuite checks.
Running the test suite on powerpc64 (and likely any other architecture) with
the runtest -v option produces output like the following, indicating that gcc
is being invoked to determine whether the target has ARM vectorization support
even though the target is known to be one other than ARM.
check_compile tool: gcc for arm_vect_no_misalign
doing compile
pid is 99288 -99288
close result is 99288 exp6 0 1
output is arm_vect_no_misalign99107.c:3:3: error: #error !__arm__ || (__ARMEL__
&& __ARM_FEATURE_UNALIGNED)
status 1
compiler exited with status 1
The attached patch adds tests to lib/target-supports.exp to avoid these
unnecessary checks.
