Hi,

The attached testsuite patch makes
gcc.target/arm/copysign_softfloat_1.c UNSUPPORTED on
arm-none-linux-gnueabihf, rather than FAIL/UNRESOLVED because of a
link failure since the toolchain startup code is in hard-float ABI
while the testcase is compiled with -mfloat-abi=soft.

Tested on arm* configurations, with no impact on arm*eabi and
FAIL->UNSUPPORTED on arm*hf targets.

OK?

Thanks,

Christophe
gcc/testsuite/ChangeLog:

2017-11-10  Christophe Lyon  <christophe.lyon@linaro.org>

	* lib/target-supports.exp (check_effective_target_arm_soft_ok):
	New function.
	* gcc.target/arm/copysign_softfloat_1.c: Require arm_soft_ok
	effective target.
