2016-07-01SPARC: fix nearbyint on sNaN inputAurelien Jarno
nearbyint and nearbyintf should not trigger inexact exceptions, but should still trigger an invalid exception for a sNaN input. The SPARC specific implementations of these functions save the FSR at the beginning of the function and restore it at the end to not trigger an inexact exception. This however doesn't work for an sNaN input which need to trigger an invalid exception. Fix that by adding a fcmp instruction using the input value before saving FSR, so that an invalid exception is triggered for a sNaN input. This fixes the math/test-nearbyint-except test on SPARC. Changelog: * sparc/sparc32/sparcv9/fpu/s_nearbyint.S (__nearbyint): Trigger an invalid exception for a sNaN input. * sparc/sparc32/sparcv9/fpu/s_nearbyintf.S (__nearbyintf): Likewise. * sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyint-vis3.S (__nearbyint_vis3): Likewise * sparc/sparc32/sparcv9/fpu/multiarch/s_nearbyintf-vis3.S (__nearbyintf_vis3): Likewise * sparc/sparc64/fpu/s_nearbyint.S (__nearbyint): Likewise. * sparc/sparc64/fpu/s_nearbyintf.S (__nearbyintf): Likewise. * sparc/sparc64/fpu/multiarch/s_nearbyint-vis3.S (__nearbyint_vis3): Likewise. * sparc/sparc64/fpu/multiarch/s_nearbyintf-vis3.S (__nearbyintf_vis3): Likewise.

2015-09-16Make scalbn set errno (bug 6803).Joseph Myers
As noted in bug 6803, scalbn fails to set errno on overflow and underflow. This patch fixes this by making scalbn an alias of ldexp, which has exactly the same semantics (for floating-point types with radix 2) and already has wrappers that deal with setting errno, instead of an alias of the internal __scalbn (which ldexp calls). Notes: * Where compat symbols were defined for scalbn functions, I didn't change what they point to (to keep the patch minimal), so such compat symbols continue to go directly to the non-errno-setting functions. * Mike, I didn't do anything with the IA64 versions of these functions, where I think both the ldexp and scalbn functions already deal with setting errno. As a cleanup (not needed to fix this bug) however you might want to make those functions into aliases for IA64; there is no need for them to be separate function implementations at all. * This concludes the fix for bug 6803 since the scalb and scalbln cases of that bug were fixed some time ago. Tested for x86_64, x86, mips64 and powerpc. [BZ #6803] * math/s_ldexp.c (scalbn): Define as weak alias of __ldexp.

2015-09-11Move bits/atomic.h to atomic-machine.h (bug 14912).Joseph Myers
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers. This patch renames bits/atomic.h to atomic-machine.h to follow that convention. This is the only change in this series that needs to change the filename rather than simply removing a directory level (because both atomic.h and bits/atomic.h exist at present). Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

2015-06-30Clean up BUSY_WAIT_NOP and atomic_delay.Torvald Riegel
This patch combines BUSY_WAIT_NOP and atomic_delay into a new atomic_spin_nop function and adjusts all clients. The new function is put into atomic.h because what is best done in a spin loop is architecture-specific, and atomics must be used for spinning. The function name is meant to tell users that this has no effect on synchronization semantics but is a performance aid for spinning.

2014-11-04Don't use INTDEF/INTUSE with _dl_init (bug 14132).Joseph Myers
Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this patch eliminates its use for _dl_init. Since _dl_init was already declared with hidden visibility, creating a second hidden alias for it was completely pointless, so this patch replaces all uses of _dl_init_internal with plain _dl_init instead of using hidden_proto / hidden_def (which are only needed when you want a hidden alias for a non-hidden symbol; it's quite possible there are cases where they are used but don't need to be because the symbol in question is not part of the public ABI and is only used within a single library, so using attributes_hidden instead would suffice). Tested for x86_64 that installed stripped shared libraries are unchanged by the patch.

2014-10-09soft-fp: Refactor exception handling for comparisons.Joseph Myers
This patch refactors how soft-fp comparisons handle setting exceptions for NaN operands, so that exceptions are set through the FP_CMP macros rather than directly in the C files calling them. The _FP_CMP* and FP_CMP* macros gain an extra argument to specify when exceptions should be set, 0 for no exception setting (I'm not sure this is actually needed - at least it's not needed for IEEE operations in glibc / libgcc, but might be relevant in some cases for kernel use), 1 for exceptions only for signaling NaNs and 2 for exceptions for all NaNs. This argument is handled through _FP_CMP_CHECK_NAN, newly called by the _FP_CMP* macros when a NaN is encountered. Calls to these macros are updated, which eliminates all the existing checking and exception setting in soft-fp *.c files in glibc. Tested for powerpc-nofpu. (The __unord* functions have no code changes; the __eq* / __ge* / __le* functions get slightly larger, but I don't think that's significant.) * soft-fp/op-common.h (_FP_CMP_CHECK_NAN): New macro.

2014-02-12soft-fp: support after-rounding tininess detection.Joseph Myers
IEEE 754-2008 defines two ways in which tiny results can be detected, "before rounding" (based on the infinite-precision result) and "after rounding" (based on the result when rounded to normal precision as if the exponent range were unbounded). All binary operations on an architecture must use the same choice of how tininess is detected. soft-fp has so far implemented only before-rounding tininess detection. This patch adds support for after-rounding tininess detection. A new macro _FP_TININESS_AFTER_ROUNDING is added that sfp-machine.h must define (soft-fp is meant to be self-contained so the existing tininess.h files aren't used here, though the information going in sfp-machine.h has been taken from them). The soft-fp macros dealing with raising underflow exceptions then handle the cases where the choice matters specially, rounding a copy of the input to the appropriate precision to see if a value that's tiny before rounding isn't tiny after rounding. Tested for mips64 using GCC trunk (which now uses soft-fp on MIPS, so supporting exceptions and rounding modes for long double where not previously supported - this is the immediate motivation for doing this patch now) together with (a) a patch to sysdeps/mips/math-tests.h to enable exceptions / rounding modes tests for long double for GCC 4.9 and later, and (b) corresponding changes applied to libgcc's soft-fp and sfp-machine.h files. In the libgcc context this is also tested on x86_64 (also an after-rounding architecture) with testcases for __float128 that I intend to add to the GCC testsuite when updating soft-fp there. (To be clear: this patch does not fix any glibc bugs that were user-visible in past releases, since after-rounding architectures didn't use soft-fp in any affected case with support for floating-point exceptions - so there is no corresponding Bugzilla bug. Rather, it works together with the GCC changes to use soft-fp on MIPS to allow previously absent long double functionality to work properly, and allows soft-fp to be used in glibc on after-rounding architectures in cases where it couldn't previously be used.) * soft-fp/op-common.h (_FP_DECL): Mark exponent as possibly unused. (_FP_PACK_SEMIRAW): Determine tininess based on rounding shifted value if _FP_TININESS_AFTER_ROUNDING and unrounded value is in subnormal range. (_FP_PACK_CANONICAL): Determine tininess based on rounding to normal precision if _FP_TININESS_AFTER_ROUNDING and unrounded value has largest subnormal exponent. * soft-fp/soft-fp.h [FP_NO_EXCEPTIONS] (_FP_TININESS_AFTER_ROUNDING): Undefine and redefine to 0. * sysdeps/aarch64/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): New macro. * sysdeps/alpha/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/arm/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/mips/mips64/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/mips/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/powerpc/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/sh/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/sparc/sparc32/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/sparc/sparc64/soft-fp/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise. * sysdeps/tile/sfp-machine.h (_FP_TININESS_AFTER_ROUNDING): Likewise.

The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value.
