testsuite: Sanitize fails for SP FPU on Arm
This patch stops reporting fails for Arm targets with single
precision floating point unit for types wider than 32 bits (the width
of float on arm-none-eabi).
As reported in PR102017, fenv is reported as supported in recent
versions of newlib. At the same time, for some Arm targets, the
implementation in libgcc does not support exceptions and thus, the
test fails with a call to abort().
gcc/testsuite/ChangeLog:
* lib/target-supports.exp
(check_effective_target_fenv_exceptions_double): New.
(check_effective_target_fenv_exceptions_long_double): New.
* gcc.dg/c2x-float-7.c: Split into 3 tests...
* gcc.dg/c2x-float-7a.c: Float part of c2x-float-7.c.
* gcc.dg/c2x-float-7b.c: Double part of c2x-float-7.c.
* gcc.dg/c2x-float-7c.c: Long double part of c2x-float-7.c.
* gcc.dg/pr95115.c: Switch to fenv_exceptions_double.
* gcc.dg/torture/float32x-nan-floath.c: Likewise.
* gcc.dg/torture/float32x-nan.c: Likewise.
* gcc.dg/torture/float64-nan-floath.c: Likewise.
* gcc.dg/torture/float64-nan.c: Likewise.
* gcc.dg/torture/inf-compare-1.c: Likewise.
* gcc.dg/torture/inf-compare-2.c: Likewise.
* gcc.dg/torture/inf-compare-3.c: Likewise.
* gcc.dg/torture/inf-compare-4.c: Likewise.
* gcc.dg/torture/inf-compare-5.c: Likewise.
* gcc.dg/torture/inf-compare-6.c: Likewise.
* gcc.dg/torture/inf-compare-7.c: Likewise.
* gcc.dg/torture/inf-compare-8.c: Likewise.
* gcc.dg/torture/pr52451.c: Likewise.
* gcc.dg/torture/pr82692.c: Likewise.
* gcc.dg/torture/inf-compare-1-float.c: New test.
* gcc.dg/torture/inf-compare-2-float.c: New test.
* gcc.dg/torture/inf-compare-3-float.c: New test.
