Joseph Myers	84c426b85d	Ignore -Wmaybe-uninitialized in stdlib/bug-getcontext.c. Doing all-ABIs compile testing produces a compiler warning in stdlib/bug-getcontext.c on nios2 and tilepro (with GCC 5 branch): bug-getcontext.c: In function 'do_test': bug-getcontext.c:53:6: error: 'except_mask' may be used uninitialized in this function [-Werror=maybe-uninitialized] if (mask != except_mask) ^ This warning appears nonsensical; except_mask is initialized where it's declared. I think what must be happening here is that the compiler is confused by the returns-twice nature of getcontext: if there were a call to setcontext, local variables could indeed have lost their values on the second return from getcontext. This patch duly uses the DIAG_* macros to disable the warning here. Tested for nios2 and tilepro (compilation only; after this patch all the tests compile, though there are other failures) and x86_64 (full testsuite run). * stdlib/bug-getcontext.c: Include <libc-internal.h>. (do_test): Disable -Wmaybe-uninitialized around uses of except_mask.	10 years ago

Chris Metcalf	0af797def3	math: support platforms with limited FP rounding or exception support For some tests, just claim that fetestexcept() always returns true, so the rest of the test can be compiled. For libm-test, provide known bogus values for unsupported rounding modes, so fesetround() will return failure. Elsewhere, just add some #ifdefs to avoid code that uses particular FP exceptions if the exceptions aren't supported.	14 years ago
Ulrich Drepper	75ea32abcd	Fix FPU context handling in getcontext on x86-64. fnstenv on x86-64 seems to clear the state. Work around.	15 years ago
