* elf: Unify symbol address run-time calculation [BZ #19818]Maciej W. Rozycki2018-04-0423-41/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wrap symbol address run-time calculation into a macro and use it throughout, replacing inline calculations. There are a couple of variants, most of them different in a functionally insignificant way. Most calculations are right following RESOLVE_MAP, at which point either the map or the symbol returned can be checked for validity as the macro sets either both or neither. In some places both the symbol and the map has to be checked however. My initial implementation therefore always checked both, however that resulted in code larger by as much as 0.3%, as many places know from elsewhere that no check is needed. I have decided the size growth was unacceptable. Having looked closer I realized that it's the map that is the culprit. Therefore I have modified LOOKUP_VALUE_ADDRESS to accept an additional boolean argument telling it to access the map without checking it for validity. This in turn has brought quite nice results, with new code actually being smaller for i686, and MIPS o32, n32 and little-endian n64 targets, unchanged in size for x86-64 and, unusually, marginally larger for big-endian MIPS n64, as follows: i686: text data bss dec hex filename 152255 4052 192 156499 26353 ld-2.27.9000-base.so 152159 4052 192 156403 262f3 ld-2.27.9000-elf-symbol-value.so MIPS/o32/el: text data bss dec hex filename 142906 4396 260 147562 2406a ld-2.27.9000-base.so 142890 4396 260 147546 2405a ld-2.27.9000-elf-symbol-value.so MIPS/n32/el: text data bss dec hex filename 142267 4404 260 146931 23df3 ld-2.27.9000-base.so 142171 4404 260 146835 23d93 ld-2.27.9000-elf-symbol-value.so MIPS/n64/el: text data bss dec hex filename 149835 7376 408 157619 267b3 ld-2.27.9000-base.so 149787 7376 408 157571 26783 ld-2.27.9000-elf-symbol-value.so MIPS/o32/eb: text data bss dec hex filename 142870 4396 260 147526 24046 ld-2.27.9000-base.so 142854 4396 260 147510 24036 ld-2.27.9000-elf-symbol-value.so MIPS/n32/eb: text data bss dec hex filename 142019 4404 260 146683 23cfb ld-2.27.9000-base.so 141923 4404 260 146587 23c9b ld-2.27.9000-elf-symbol-value.so MIPS/n64/eb: text data bss dec hex filename 149763 7376 408 157547 2676b ld-2.27.9000-base.so 149779 7376 408 157563 2677b ld-2.27.9000-elf-symbol-value.so x86-64: text data bss dec hex filename 148462 6452 400 155314 25eb2 ld-2.27.9000-base.so 148462 6452 400 155314 25eb2 ld-2.27.9000-elf-symbol-value.so [BZ #19818] * sysdeps/generic/ldsodefs.h (LOOKUP_VALUE_ADDRESS): Add `set' parameter.

* Filter out NPTL internal signals (BZ #22391)Adhemerval Zanella2018-04-036-46/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch filters out the internal NPTL signals (SIGCANCEL/SIGTIMER and SIGSETXID) from signal functions. GLIBC on Linux requires both signals to proper implement pthread cancellation, posix timers, and set*id posix thread synchronization. And not filtering out the internal signal is troublesome: - A conformant program on a architecture that does not filter out the signals might inadvertently disable pthread asynchronous cancellation, set*id synchronization or posix timers. - It might also to security issues if SIGSETXID is masked and set*id functions are called (some threads might have effective user or group id different from the rest). The changes are basically: - Change __is_internal_signal to bool and used on all signal function that has a signal number as input. Also for signal function which accepts signals sets (sigset_t) it assumes that canonical function were used to add/remove signals which lead to some input simplification. - Fix tst-sigset.c to avoid check for SIGCANCEL/SIGTIMER and SIGSETXID. It is rewritten to check each signal indidually and to check realtime signals using canonical macros. - Add generic __clear_internal_signals and __is_internal_signal version since both symbols are used on generic implementations. - Remove superflous sysdeps/nptl/sigfillset.c. - Remove superflous SIGTIMER handling on Linux __is_internal_signal since it is the same of SIGCANCEL. - Remove dangling define and obvious comment on nptl/sigaction.c. Checked on x86_64-linux-gnu.

* [PATCH 7/7] sin/cos slow paths: refactor sincos implementationWilco Dijkstra2018-04-032-45/+52
| | | | | | | | | | | | | Refactor the sincos implementation - rather than rely on odd partial inlining of preprocessed portions from sin and cos, explicitly write out the cases. This makes sincos much easier to maintain and provides an additional 16-20% speedup between 0 and 2^27. The overall speedup of sincos is 48% over this range. Between 0 and PI it is 66% faster. * sysdeps/ieee754/dbl-64/s_sin.c (__sin): Cleanup ifdefs.

* [PATCH 6/7] sin/cos slow paths: refactor duplicated code into dosinWilco Dijkstra2018-04-031-27/+13
| | | | | | | | | | | | | | Refactor duplicated code into do_sin. Since all calls to do_sin use copysign to set the sign of the result, move it inside do_sin. Small inputs use a separate polynomial, so move this into do_sin as well (the check is based on the more conservative case when doing large range reduction, but could be relaxed). * sysdeps/ieee754/dbl-64/s_sin.c (do_sin): Use TAYLOR_SIN for small inputs. Return correct sign. (do_sincos): Remove small input check before do_sin, let do_sin set the sign. (__sin): Likewise. (__cos): Likewise.

* [PATCH 3/7] sin/cos slow paths: remove slow paths from small range reductionWilco Dijkstra2018-04-032-53/+47
| | | | | | | | | | | | | | | | This patch improves the accuracy of the range reduction. When the input is large (2^27) and very close to a multiple of PI/2, using 110 bits of PI is not enough. Improve range reduction accuracy to 136 bits. As a result the special checks for results close to zero can be removed. The ULP of the polynomials is at worst 0.55ULP, so there is no reason for the slow functions, and they can be removed. * sysdeps/ieee754/dbl-64/s_sin.c (reduce_sincos_1): Rename to reduce_sincos, improve accuracy to 136 bits. (do_sincos_1): Rename to do_sincos, remove fallbacks to slow functions. (__sin): Use improved reduction and simplified do_sincos calculation. (__cos): Likewise. * sysdeps/ieee754/dbl-64/s_sincos.c (__sincos): Likewise.
* [PATCH 2/7] sin/cos slow paths: remove large range reductionWilco Dijkstra2018-04-032-103/+2
| | | | | | | | | | | | | | | | | | | | This patch removes the large range reduction code and defers to the huge range reduction code. The first level range reducer supports inputs up to 2^27, which is way too large given that inputs for sin/cos are typically small (< 10), and optimizing for a smaller range would give a significant speedup. Input values above 2^27 are practically never used, so there is no reason for supporting range reduction between 2^27 and 2^48. Removing it significantly simplifies code and enables further speedups. There is about a 2.3x slowdown in this range due to __branred being extremely slow (a better algorithm could easily more than double performance). * sysdeps/ieee754/dbl-64/s_sin.c (reduce_sincos_2): Remove function. (do_sincos_2): Likewise. (__sin): Remove middle range reduction case. (__cos): Likewise. * sysdeps/ieee754/dbl-64/s_sincos.c (__sincos): Remove middle range reduction case.
* [PATCH 1/7] sin/cos slow paths: avoid slow paths for small inputsWilco Dijkstra2018-04-033-26/+26
| | | | | | | | | | | | | | | | | | | | | | | | This series of patches removes the slow patchs from sin, cos and sincos. Besides greatly simplifying the implementation, the new version is also much faster for inputs up to PI (41% faster) and for large inputs needing range reduction (27% faster). ULP is ~0.55 with no errors found after testing 1.6 billion inputs across most of the range with mpsin and mpcos. The number of incorrectly rounded results (ie. ULP >0.5) is at most ~2750 per million inputs between 0.125 and 0.5, the average is ~850 per million between 0 and PI. Tested on AArch64 and x86_64 with no regressions. The first patch removes the slow paths for the cases where the input is small and doesn't require range reduction. Update ULP tables for sin, cos and sincos on AArch64 and x86_64. * sysdeps/aarch64/libm-test-ulps: Update ULP for sin, cos, sincos. * sysdeps/ieee754/dbl-64/s_sin.c (__sin): Remove slow paths for small inputs. (__cos): Likewise. * sysdeps/x86_64/fpu/libm-test-ulps: Update ULP for sin, cos, sincos.

This allows remove both the fallback code to handle system with missing or broken O_DIRECTORY along with the Linux specific opendir.c which just advertise the working flag. Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and powerpc64le-linux-gnu. * sysdeps/posix/opendir.c (o_directory_works, tryopen_o_directory): Remove definitions.

Different than other architectures SPARC kernel Kconfig does not define CONFIG_CLONE_BACKWARDS, however it has the same ABI as if it did, implemented by sparc-specific code (sparc_do_fork). It also has a unique return value convention for clone: Parent --> %o0 == child's pid, %o1 == 0 Child --> %o0 == parent's pid, %o1 == 1 Which required a special macro to correct issue the syscall (INLINE_CLONE_SYSCALL).

* Unify umount function implementations (bug 16552).Joseph Myers2018-03-268-133/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux kernel architectures have various arrangements for umount syscalls. There is a syscall that takes flags, and an older one that does not. Newer architectures have only the one taking flags, under the name umount2 (or under the name umount, in the ia64 case). Older architectures may have both, under the names umount2 and umount (or under the names umount and oldumount, in the alpha case). glibc then has several similar implementations of the umount function (no flags) in terms of either the __umount2 function, or the corresponding syscall, or in terms of the old syscall under either of its names. This patch simplifies the implementations in glibc by always using the __umount2 function to implement the umount function on all systems using the Linux kernel. The linux/generic implementation is moved to sysdeps/unix/sysv/linux (without any changes to code or comments) and all the other variants are removed. (This will have the effect of causing the new syscall to be used in some cases that previously used the old one, but as discussed for previous changes, such a change to the underlying syscalls used is OK.) There remain two variants of how the __umount2 function is implemented, either in umount2.S, or, for ia64, in syscalls.list. Tested with build-many-glibcs.py.

* Remove unused frame.h header, sigcontextinfo.h macros.Joseph Myers2018-03-2220-210/+0

Similarly, there are some sigcontextinfo.h macros that are used nowhere in glibc - ADVANCE_STACK_FRAME and FIRST_FRAME_POINTER were used in the old debug/backtrace.c, while SIGCONTEXT_EXTRA_ARGS, GET_FRAME, GET_STACK and CALL_SIGHANDLER were unused even before the removal of that old implementation (beyond uses of SIGCONTEXT_EXTRA_ARGS in definitions of CALL_SIGHANDLER).

* Use x86_64 backtrace as generic version.Joseph Myers2018-03-2110-143/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | No glibc configuration uses the present debug/backtrace.c, whereas several #include the x86_64 version. The x86_64 version is effectively a generic one (using _Unwind_Backtrace from libgcc, which works much more reliably than the built-in functions used by debug/backtrace.c). This patch moves it to debug/backtrace.c and removes all the #includes of the x86_64 version from other architectures which are no longer required. I do not know whether all the other architecture-specific backtrace implementations that are based on _Unwind_Backtrace are required, or whether, where their differences from the generic version do something useful, suitable hooks could be added to the generic version to reduce the duplication involved. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/x86_64/backtrace.c: Move to .... * debug/backtrace.c: ... here. * sysdeps/aarch64/backtrace.c: Remove file. * sysdeps/alpha/backtrace.c: Likewise. * sysdeps/hppa/backtrace.c: Likewise. * sysdeps/ia64/backtrace.c: Likewise. * sysdeps/mips/backtrace.c: Likewise. * sysdeps/nios2/backtrace.c: Likewise. * sysdeps/riscv/backtrace.c: Likewise. * sysdeps/sh/backtrace.c: Likewise. * sysdeps/tile/backtrace.c: Likewise.
* Remove powerpc, sparc fdim inlines (bug 22987).Joseph Myers2018-03-202-71/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The powerpc and sparc bits/mathinline.h include inlines of fdim and fdimf. These are not restricted to -fno-math-errno, but do not set errno, and wrongly use ordered <= comparisons instead of the required islessequal comparisons (this latter issue is latent on powerpc because GCC wrongly uses unordered comparison instructions for operations that should use ordered comparison instructions). Since we wish to avoid such header inlines anyway, leaving it to the compiler to inline such standard functions under appropriate conditions, this patch fixes those issues by removing the inlines in question (and thus removing the sparc bits/mathinline.h header which had no other inlines left in it). I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85003> for adding correct fdim inlines to GCC, since the function is simple enough that a correct inline is a perfectly reasonable architecture-independent optimization with -fno-math-errno and in the absence of implicit excess precision. Tested with build-many-glibcs.py for all its powerpc and sparc configurations. [BZ #22987] * sysdeps/powerpc/bits/mathinline.h (fdim): Remove inline function. (fdimf): Likewise. * sysdeps/sparc/fpu/bits/mathinline.h: Remove file.
