Hey,
Previously, this test was added to fix this bug:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112337. However, it did not check
the compilation options before using them, leading to errors.
This patch fixes the test by first checking whether it can use the options
before using them.
Tested for arm-none-eabi and found no regressions. The output of check-gcc with
RUNTESTFLAGS="arm.exp=*" changed like this:
Before:
# of expected passes 5963
# of unexpected failures 64
After:
# of expected passes 5964
# of unexpected failures 63
Ok for master?

gcc/testsuite/ChangeLog:
* gcc.target/arm/pr112337.c: Check whether we can use the compilation
options before using them.
My apologies for missing this earlier. It didn't show up in patchwork. That's
most likely because the attachment is a binary blob instead of text/plain.
That also means that the Linaro CI system hasn't seen this patch either.
Please can you fix your mailer to add plain text patch files.
-/* { dg-options "-O2 -march=armv8.1-m.main+fp.dp+mve.fp -mfloat-abi=hard" } */
+/* { dg-require-effective-target arm_hard_ok } */
+/* { dg-require-effective-target arm_v8_1m_mve_ok } */
+/* { dg-options "-O2 -mfloat-abi=hard" } */
+/* { dg-add-options arm_v8_1m_mve } */
This is moving in the right direction, but it adds more than necessary now:
checking for, and adding -mfloat-abi=hard is not necessary any more as
arm_v8_1m_mve_ok will work out what float-abi flags are needed to make the
options work. (What's more, it will prevent the test from running if the base
configuration of the compiler is incompatible with the hard float ABI, which is
more than we need.).
So please can you re-spin removing the hard-float check and removing that from
dg-options.
Thanks,
R.
Hi Richard,
Agreed with your comments. Please find the patch with the suggested
changes attached.
