Bug ID: 101375
Summary: arm: Adding -mfpu=auto makes many tests unsupported
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
Target Milestone: ---
While looking at updating my validation configs to use -mfpu=auto, I noticed
that adding this options makes many tests unsupported. Given that most of them
actually check if -mfpu is overridden, maybe I shouldn't add -mfpu=auto?
Specifically, for arm-none-eabi, configured with default cpu/fpu/mode, and
running the tests with
-mcpu=cortex-a7/-mfloat-abi=hard/-march=armv7ve+simd/-mfpu=auto
instead of
-mcpu=cortex-a7/-mfloat-abi=hard/-march=armv7ve+simd
results in:

instead of all passes.
This essentially means these tests become unsupported in all the configs I'm
testing, thus I'm worried about test coverage.
