Zack Weinberg	e15f7de60c	Split DIAG_* macros to new header libc-diag.h. Quite a few tests include libc-internal.h just for the DIAG_* macros. Split those macros to their own file, which can be included safely in _ISOMAC mode. I also moved ignore_value, since it seems logically related, even though I didn't notice any tests needing it. Also add -Wnonnull suppressions to two tests that _should_ have them, but the error is masked when compiling against internal headers. * include/libc-diag.h: New file. Define ignore_value, DIAG_PUSH_NEEDS_COMMENT, DIAG_POP_NEEDS_COMMENT, DIAG_IGNORE_NEEDS_COMMENT, and DIAG_IGNORE_Os_NEEDS_COMMENT here. * include/libc-internal.h: Definitions of above macros moved from here. Include libc-diag.h. Add copyright notice. * malloc/tst-malloc.c, malloc/tst-memcheck.c, malloc/tst-realloc.c * misc/tst-error1.c, posix/tst-dir.c, stdio-common/bug21.c * stdio-common/scanf14.c, stdio-common/scanf4.c, stdio-common/scanf7.c * stdio-common/test-vfprintf.c, stdio-common/tst-printf.c * stdio-common/tst-printfsz.c, stdio-common/tst-sprintf.c * stdio-common/tst-unlockedio.c, stdio-common/tstdiomisc.c * stdlib/bug-getcontext.c, string/tester.c, string/tst-endian.c * time/tst-strptime2.c, wcsmbs/tst-wcstof.c: Include libc-diag.h instead of libc-internal.h. * stdlib/tst-environ.c: Include libc-diag.h. Suppress -Wnonnull for call to unsetenv (NULL). * nptl/tst-mutex1.c: Include libc-diag.h. Suppress -Wnonnull for call to pthread_mutexattr_destroy (NULL).	10 years ago
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
