* Make fallback fesetexceptflag always succeed (bug 21028).Joseph Myers2017-01-051-1/+7
| | | | | | | | | | | | | | | | | | | | The fallback implementation of fesetexceptflag currently fails if any exceptions are specified. It should always succeed, because the exception state is always that all exceptions (if any are defined in <fenv.h> but not supported in this configuration) are always clear, just as fallback fetestexcept always succeeds and fallback fesetenv always succeeds unless asked to set FE_NOMASK_ENV. This patch fixes it accordingly. Together with the patch to test-fexcept.c to allow feraiseexcept to fail in another place, this stops that test from failing for MIPS soft-float. Tested for mips64 soft-float. [BZ #21028] * math/fsetexcptflg.c (__fesetexceptflag): Always return 0. * math/test-fexcept.c (test_set): Allow failure of feraiseexcept if EXCEPTION_TESTS returns false.

* Fix test-fexcept when "inexact" implicitly raised.Joseph Myers2016-08-121-2/+31
| | | | | | | | | | | | | | | | | | ISO C allows feraiseexcept to raise "inexact", in addition to the requested exceptions, when requested to raise "overflow" or "underflow". Testing on ARM and PowerPC e500 (where glibc's feraiseexcept has this property) showed that the new test-fexcept test failed to allow for this; this patch fixes it, by wrapping feraiseexcept to clear FE_INEXACT if implicitly raised and not raised before the call. (It would also be possible to do this with fesetexcept, which always affects exactly the requested flags, but this patch avoids making this fix depend on the fesetexcept changes.) Tested for x86_64, x86, arm and e500. * math/test-fexcept.c (feraiseexcept_exact): New function. (test_set): Call feraiseexcept_exact instead of feraiseexcept. (test_except): Likewise.
* Add tests for fegetexceptflag, fesetexceptflag.Joseph Myers2016-08-101-0/+171
I noticed that there was no meaningful test coverage for fegetexceptflag and fesetexceptflag (one test ensures that calls to them compile and link, but nothing to verify they work correctly). This patch adds tests for these functions. fesetexceptflag is meant to set the relevant exception flag bits to the saved state without causing enabled traps to be taken. On some architectures, it is not possible to set exception flag bits without causing enabled traps to occur. Such architectures need to define EXCEPTION_SET_FORCES_TRAP to 1 in their math-tests.h, as is done in this patch for powerpc. x86 avoids needing to define this because the traps resulting from setting exception bits don't occur until the next floating-point operation or fwait instruction. Tested for x86_64, x86 and powerpc. Note that test-fexcept fails for powerpc because of a pre-existing bug in fesetexceptflag for powerpc, which I'll fix separately. * math/test-fexcept-traps.c: New file. * math/test-fexcept.c: Likewise. * math/Makefile (tests): Add test-fexcept and test-fexcept-traps. * sysdeps/generic/math-tests.h (EXCEPTION_SET_FORCES_TRAP): New macro. * sysdeps/powerpc/math-tests.h [!__NO_FPRS__] (EXCEPTION_SET_FORCES_TRAP): Likewise.
