2016-12-27powerpc: Remove f{max,min}{f} assembly implementationsAdhemerval Zanella
This patch removes the powerpc assembly implementation of fmax/fmin. Based on benchtests, the assembly ones shows: $ ./testrun.sh benchtests/bench-fmax "fmax": { "": { "duration": 5.07586e+09, "iterations": 2.01676e+09, "max": 1350.39, "min": 2.073, "mean": 2.51684 }, "qNaN": { "duration": 5.09315e+09, "iterations": 8.4568e+08, "max": 2788, "min": 5.806, "mean": 6.02255 }, "sNaN": { "duration": 5.09073e+09, "iterations": 8.42316e+08, "max": 4215.84, "min": 5.737, "mean": 6.04373 } And $ ./testrun.sh benchtests/bench-fmin "fmin": { "": { "duration": 5.07711e+09, "iterations": 2.02982e+09, "max": 497.094, "min": 2.073, "mean": 2.50126 }, "qNaN": { "duration": 5.09134e+09, "iterations": 8.46968e+08, "max": 2255.14, "min": 5.807, "mean": 6.01125 }, "sNaN": { "duration": 5.09122e+09, "iterations": 8.4746e+08, "max": 1969.38, "min": 5.729, "mean": 6.00763 } } The default implementation (math/s_f{max.min}_template.c) shows slight better latency for all cases: $ ./testrun.sh benchtests/bench-fmax "fmax": { "": { "duration": 5.07044e+09, "iterations": 2.38695e+09, "max": 2048.58, "min": 2.073, "mean": 2.12423 }, "qNaN": { "duration": 5.09004e+09, "iterations": 9.45428e+08, "max": 3306.93, "min": 5.138, "mean": 5.38385 }, "sNaN": { "duration": 5.08458e+09, "iterations": 1.15959e+09, "max": 972.008, "min": 3.321, "mean": 4.3848 } } And: $ ./testrun.sh benchtests/bench-fmin "fmin": { "": { "duration": 5.06817e+09, "iterations": 2.3913e+09, "max": 1177.9, "min": 2.073, "mean": 2.11942 }, "qNaN": { "duration": 5.08857e+09, "iterations": 9.45656e+08, "max": 2658.83, "min": 5.09, "mean": 5.38099 }, "sNaN": { "duration": 5.08093e+09, "iterations": 1.16725e+09, "max": 1030.74, "min": 3.323, "mean": 4.3529 } } Both were run with GCC 5.4 (ubuntu 16 default installation) using default compiler flags on POWER8E 3.4GHz (powerpc64le-linux-gnu).
2016-11-29powerpc: Add hidden definition for __sigsetjmpFlorian Weimer
There already is a hidden prototype for __sigsetjmp, but the architecture-specific definition was missing.
2016-11-29powerpc: Remove unintended __longjmp symbol from ABIFlorian Weimer
The __longjmp symbol was left in accidentally. It is not exported through a Versions file, but through a .symver assembler directive. The corresponding exported symbol was removed from the non-fpu powerpc64 targets in commit 9b9ef823581ecee546653d6ac3fd335f7b79faca.
2016-10-19Stop powerpc copysignl raising "invalid" for sNaN argument (bug 20718).Joseph Myers
The powerpc (hard-float) implementations of copysignl, both 32-bit and 64-bit, raise spurious "invalid" exceptions when the first argument is a signaling NaN. copysign functions should never raise exceptions even for signaling NaNs. The problem is the use of an fcmpu instruction to test the sign of the high part of the long double argument. This patch fixes the functions to use fsel instead (as used for fabsl following my fixes for a similar bug there), or to examine the integer representation for older 32-bit processors without fsel. Tested for powerpc64 and powerpc32 (configurations with and without fsel used). [BZ #20718] * sysdeps/powerpc/powerpc32/fpu/s_copysignl.S (__copysignl): Do not use floating-point comparisons to test sign. * sysdeps/powerpc/powerpc64/fpu/s_copysignl.S (__copysignl): Likewise.
2016-06-14Use generic fdim on more architectures (bug 6796, bug 20255, bug 20256).Joseph Myers
Some architectures have their own versions of fdim functions, which are missing errno setting (bug 6796) and may also return sNaN instead of qNaN for sNaN input, in the case of the x86 / x86_64 long double versions (bug 20256). These versions are not actually doing anything that a compiler couldn't generate, just straightforward comparisons / arithmetic (and, in the x86 / x86_64 case, testing for NaNs with fxam, which isn't actually needed once you use an unordered comparison and let the NaNs pass through the same subtraction as non-NaN inputs). This patch removes the x86 / x86_64 / powerpc versions, so that those architectures use the generic C versions, which correctly handle setting errno and deal properly with sNaN inputs. This seems better than dealing with setting errno in lots of .S versions. The i386 versions also return results with excess range and precision, which is not appropriate for a function exactly defined by reference to IEEE operations. For errno setting to work correctly on overflow, it's necessary to remove excess range with math_narrow_eval, which this patch duly does in the float and double versions so that the tests can reliably pass on x86. For float, this avoids any double rounding issues as the long double precision is more than twice that of float. For double, double rounding issues will need to be addressed separately, so this patch does not fully fix bug 20255. Tested for x86_64, x86 and powerpc.

2016-05-27Fix powerpc32 ceil, rint etc. on sNaN input (bug 20160).Joseph Myers
The powerpc32 versions of ceil, floor, round, trunc, rint, nearbyint and their float versions return sNaN for sNaN input when they should return qNaN. This patch fixes them to add a NaN argument to itself to quiet sNaNs before returning. The powerpc64 versions, which have the same bug, will be addressed separately. Tested for powerpc32.

2016-05-27Avoid "invalid" exceptions from powerpc fabsl (sNaN) (bug 20157).Joseph Myers
The powerpc implementations of fabsl for ldbl-128ibm (both powerpc32 and powerpc64) wrongly raise the "invalid" exception for sNaN arguments. fabs functions should be quiet for all inputs including signaling NaNs. The problem is the use of a comparison instruction fcmpu to determine if the high part of the argument is negative and so the low part needs to be negated; such instructions raise "invalid" for sNaNs. There is a pure integer implementation of fabsl in sysdeps/ieee754/ldbl-128ibm/s_fabsl.c. However, it's not necessary to use it to avoid such exceptions. The fsel instruction does not raise exceptions for sNaNs, and can be used in place of the original comparison. (Note that if the high part is zero or a NaN, it does not matter whether the low part is negated; the choice of whether the low part of a zero is +0 or -0 does not affect the value, and the low part of a NaN does not affect the value / payload either.) The condition in GCC for fsel to be available is TARGET_PPC_GFXOPT, corresponding to the _ARCH_PPCGR predefined macro. fsel is available on all 64-bit processors supported by GCC. A few 32-bit processors supported by GCC do not have TARGET_PPC_GFXOPT despite having hard float support. To support those processors, integer code (similar to that in copysignl) is included for the !_ARCH_PPCGR case for powerpc32. Tested for powerpc32 (configurations with and without _ARCH_PPCGR) and powerpc64. [BZ #20157] * sysdeps/powerpc/powerpc32/fpu/s_fabsl.S (__fabsl): Use fsel to determine whether to negate low half if [_ARCH_PPCGR], and integer comparison otherwise. * sysdeps/powerpc/powerpc64/fpu/s_fabsl.S (__fabsl): Use fsel to determine whether to negate low half.
2016-05-25Do not raise "inexact" from powerpc32 ceil, floor, trunc (bug 15479).Joseph Myers
Continuing fixes for ceil, floor and trunc functions not to raise the "inexact" exception, this patch fixes the versions used on older powerpc32 processors. As was done with the round implementations some time ago, the save of floating-point state is moved after the first floating-point operation on the input to ensure that any "invalid" exception from signaling NaN input is included in the saved state, and then the whole state gets restored rather than just the rounding mode. This has no effect on configurations using the power5+ code, since such processors can do these operations with a single instruction (and those instructions do not set "inexact", so are correct for TS 18661-1 semantics). Tested for powerpc32. [BZ #15479] * sysdeps/powerpc/powerpc32/fpu/s_ceil.S (__ceil): Move save of floating-point state after first floating-point operation on input.

2015-11-12Fix powerpc round, roundf spurious "inexact" (bug 19238).Joseph Myers
The powerpc hard-float round and roundf functions, both 32-bit and 64-bit, raise spurious "inexact" exceptions for integer arguments from adding 0.5 and rounding to integer toward zero. Since these functions already save and restore the rounding mode, it's natural to make them restore the full floating-point state instead to fix this bug, which this patch does. The save of the state is moved after the first floating-point operation on the input so that any "invalid" exceptions from signaling NaN inputs are properly preserved. As a consequence of this approach to the fix, "inexact" for noninteger arguments (disallowed by TS 18661-1 but not by C99/C11, see bug 15479) is also avoided for these implementations; this is *not* a general fix for bug 15479 since plenty of other implementations of various functions still raise spurious "inexact" for noninteger arguments. This issue and fix do not apply to builds using power5+ versions of round and roundf, which use the frin instruction and avoid "inexact" exceptions that way. This patch should get hard-float powerpc32 and powerpc64 (default function implementations) back to a state where test-float and test-double will pass after ulps regeneration. Tested for powerpc32 and powerpc64. [BZ #15479] [BZ #19238] * sysdeps/powerpc/powerpc32/fpu/s_round.S (__round): Save floating-point state after first operation on input.

2015-11-11Fix powerpc nearbyint wrongly clearing "inexact" and leaving traps disabled ↵Joseph Myers
(bug 19228). Similar to bug 15491 recently fixed for x86_64 / x86, the powerpc (both powerpc32 and powerpc64) hard-float implementations of nearbyintf and nearbyint wrongly clear an "inexact" exception that was raised before the function was called; this shows up as failure of the test math/test-nearbyint-except added when that bug was fixed. They also wrongly leave traps on "inexact" disabled if they were enabled before the function was called. This patch fixes the bugs similar to how the x86 bug was fixed: saving and restoring the whole floating-point state, both to restore the original "inexact" flag state and to restore the original state of whether traps on "inexact" were enabled. Because there's a convenient point in the powerpc implementations to save state after any sNaN arguments will have raised "invalid" but before "inexact" traps need to be disabled, no special handling for "invalid" is needed as in the x86 version. Tested for powerpc64 and powerpc32, where it fixes the math/test-nearbyint-except failure as well as fixing the new test math/test-nearbyint-except-2 added by this patch. Also tested for x86_64 and x86 that the new test passes. If powerpc experts see a more efficient way of doing this (e.g. instruction positioning that's better for pipelines on typical processors) then of course followups optimizing the fix are welcome. [BZ #19228] * sysdeps/powerpc/powerpc32/fpu/s_nearbyint.S (__nearbyint): Save and restore full floating-point state. * sysdeps/powerpc/powerpc32/fpu/s_nearbyintf.S (__nearbyintf): Likewise. * sysdeps/powerpc/powerpc64/fpu/s_nearbyint.S (__nearbyint): Likewise. * sysdeps/powerpc/powerpc64/fpu/s_nearbyintf.S (__nearbyintf): Likewise. * math/test-nearbyint-except-2.c: New file. * math/Makefile (tests): Add test-nearbyint-except-2.
2015-10-14Fix powerpc32 lround, lroundf spurious exceptions (bug 19134).Joseph Myers
The powerpc32 implementation of lround and lroundf can produce spurious exceptions from adding 0.5 then converting to integer. This includes "inexact" from the conversion to integer (not allowed for integer arguments to these functions), and, for larger integer arguments, "inexact", and "overflow" when rounding upward, from the addition. In addition, "inexact" is not allowed together with "invalid" and so inexact addition must be avoided when the integer will be out of range of 32-bit long, whether or not the argument is an integer. This patch fixes these problems. As in the powerpc64 llround implementation, a check is added for too-large arguments; in the powerpc64 case that means arguments at least 2^52 in magnitude (so that 0.5 cannot be added exactly), while in this case it means arguments for which the result would overflow "long". In those cases a suitable overflowing value is used for the integer conversion without adding 0.5, while for smaller arguments it's tested whether the argument is an integer (by adding and subtracting 2^52 to the absolute value and comparing with the original absolute value) to avoid adding 0.5 to integers and generating spurious "inexact". This code is not used when the power5+ sysdeps directories are used, as there's a separate power5+ version of these functions.. Tested for powerpc. This gets test-float (for a default powerpc32 hard-float build without any --with-cpu) back to the point where it should pass once powerpc ulps are regenerated; test-double still needs another problem with exceptions fixed to get back to that point (and I haven't looked lately at what default powerpc64 results are like). [BZ #19134] * sysdeps/powerpc/powerpc32/fpu/s_lround.S (.LC1): New object. (.LC2): Likewise. (.LC3): Likewise. (__lround): Do not add 0.5 to integer or out-of-range arguments.
2015-10-13Fix powerpc32 llround, llroundf exceptions (bug 19125).Joseph Myers
The powerpc32 implementations of llroundf and llround produce spurious and missing exceptions (some arising from such exceptions from conversions to long long, some present even when fctidz is used). This patch fixes those problems in a similar way to the llrint / llrintf fixes. The spurious exceptions in the fctidz case for large arguments arise from a converted value that saturated as LLONG_MAX being converted back to float or double (the conversion back being inexact, but "inexact" must not be raised together with "invalid"), and from the subtraction x - xrf also being inexact for sufficiently large arguments (whether the saturation was to LLONG_MAX or LLONG_MIN); those are fixed by returning early if the argument is large enough that no rounding is needed. This code is not used for --with-cpu=power4 builds (I suspect the code used in that case may also produce spurious "inexact" exceptions, but that's something to investigate later). Tested for powerpc. [BZ #19125] * sysdeps/powerpc/powerpc32/fpu/s_llround.c: Include <limits.h>, <math_private.h> and <stdint.h>. (__llround): Avoid conversions to and from long long int, and subtractions, where those might raise spurious exceptions. * sysdeps/powerpc/powerpc32/fpu/s_llroundf.c: Include <math_private.h> and <stdint.h>.

sysdeps/powerpc/fpu/ has versions of llround and llroundf that are actually used only for powerpc32 because sysdeps/powerpc/powerpc64/fpu/ has its own versions of those functions.

2015-10-13Fix powerpc32 llrint, llrintf bad exceptions (bug 16422).Joseph Myers
The versions of llrint and llrintf for older powerpc32 processors convert the results of __rint / __rintf to long long int, resulting in spurious exceptions from such casts in certain cases. This patch makes glibc work around the problems with the libgcc conversions when the compiler used to build glibc doesn't use the fctidz instruction for them. Tested for powerpc.

2015-10-05Work around powerpc32 integer 0 converting to -0 (bug 887, bug 19049, bug ↵Joseph Myers
19050). On powerpc32 hard-float, older processors (ones where fcfid is not available for 32-bit code), GCC generates conversions from integers to floating point that wrongly convert integer 0 to -0 instead of +0 in FE_DOWNWARD mode. This in turn results in logb and a few other functions wrongly returning -0 when they should return +0. This patch works around this issue in glibc as I proposed in <https://sourceware.org/ml/libc-alpha/2015-09/msg00728.html>, so that the affected functions can be correct and the affected tests pass in the absence of a GCC fix for this longstanding issue (GCC bug 67771 - if fixed, of course we can put in GCC version conditionals, and eventually phase out the workarounds). A new macro FIX_INT_FP_CONVERT_ZERO is added in a new sysdeps header fix-int-fp-convert-zero.h, and the powerpc32/fpu version of that header defines the macro based on the results of a configure test for whether such conversions use the fcfid instruction. Tested for x86_64 (that installed stripped shared libraries are unchanged by the patch) and powerpc (that HAVE_PPC_FCFID comes out to 0 as expected and that the relevant tests are fixed). Also tested a build with GCC configured for -mcpu=power4 and verified that HAVE_PPC_FCFID comes out to 1 in that case. There are still some other issues to fix to get test-float and test-double passing cleanly for older powerpc32 processors (apart from the need for an ulps regeneration for powerpc). (test-ldouble will be harder to get passing cleanly, but with a combination of selected fixes to ldbl-128ibm code that don't involve significant performance issues, allowing spurious underflow and inexact exceptions for that format, and lots of XFAILing for the default case of unpatched libgcc, it should be doable.)

This patch fixes the powerpc32 optimized nearbyint/nearbyintf bogus results for FE_DOWNWARD rounding mode. This is due wrong instructions sequence used in the rounding calculation (two subtractions instead of adition and a subtraction). Fixes BZ#16815.

This patch add static probes for setjmp/longjmp in the way gdb expects,fixing the gdb.base/longjmp.exp gdb testcases. It changes the symbol_name and use macros to to avoid change the probe names and ending up adding more logic on GDB (since with the expected name GDB work seamlessly).
2013-10-04PowerPC ugly symbol versioningAlan Modra
http://sourceware.org/ml/libc-alpha/2013-08/msg00090.html This patch fixes symbol versioning in setjmp/longjmp. The existing code uses raw versions, which results in wrong symbol versioning when you want to build glibc with a base version of 2.19 for LE. Note that the merging the 64-bit and 32-bit versions in novmx-lonjmp.c and pt-longjmp.c doesn't result in GLIBC_2.0 versions for 64-bit, due to the base in shlib_versions. * sysdeps/powerpc/longjmp.c: Use proper symbol versioning macros. * sysdeps/powerpc/novmx-longjmp.c: Likewise. * sysdeps/powerpc/powerpc32/bsd-_setjmp.S: Likewise. * sysdeps/powerpc/powerpc32/bsd-setjmp.S: Likewise. * sysdeps/powerpc/powerpc32/fpu/__longjmp.S: Likewise. * sysdeps/powerpc/powerpc32/fpu/setjmp.S: Likewise. * sysdeps/powerpc/powerpc32/mcount.c: Likewise. * sysdeps/powerpc/powerpc32/setjmp.S: Likewise. * sysdeps/powerpc/powerpc64/setjmp.S: Likewise. * nptl/sysdeps/unix/sysv/linux/powerpc/pt-longjmp.c: Likewise.
2013-10-04PowerPC LE setjmp/longjmpAnton Blanchard
http://sourceware.org/ml/libc-alpha/2013-08/msg00089.html Little-endian fixes for setjmp/longjmp. When writing these I noticed the setjmp code corrupts the non volatile VMX registers when using an unaligned buffer. Anton fixed this, and also simplified it quite a bit. The current code uses boilerplate for the case where we want to store 16 bytes to an unaligned address. For that we have to do a read/modify/write of two aligned 16 byte quantities. In our case we are storing a bunch of back to back data (consective VMX registers), and only the start and end of the region need the read/modify/write.

2013-04-01PowerPC: remove branch prediction from rint implementationAdhemerval Zanella
The branch prediction hints is actually hurts performance in this case. The assembly implementation make two assumptions: 1. 'fabs (x) < 2^52' is unlikely and 2. 'x > 0.0' is unlike (if 1. is true). Since it a general floating point function, expected input is not bounded and then it is better to let the hardware handle the branches.
