* PowerPC64 strncpy, stpncpy and strstr fixesAlan Modra2017-06-149-0/+56
| | | | | | | | | | | | | | | | | | | | | Makes __stpncpy_power8 call __memset_power8 directly rather than via an IFUNC. Fixes a missing _mcount, and removes some redundant NOPS. The *_is_local defines are also used in a followup patch. * sysdeps/powerpc/powerpc64/multiarch/strncpy-power7.S: Define MEMSET_is_local. * sysdeps/powerpc/powerpc64/multiarch/strncpy-power8.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/stpncpy-power7.S: Likewise. * sysdeps/powerpc/powerpc64/multiarch/stpncpy-power8.S: Likewise.

* PowerPC64 sysdep.h tidyAlan Modra2017-06-143-59/+74
| | | | | | | | | | | | | | | | | | | | | | .align on some targets takes a byte alignment, on others like powerpc, log2 of the byte alignment. It's a good idea to avoid .align, particularly since x86 and powerpc are different. This patch fixes the occurrences of .align in powerpc64/sysdep.h, renames DOT_LABEL since the macro doesn't have anything to do with adding dots, removes extraneous semicolons, and fixes some formatting. * sysdeps/powerpc/powerpc64/sysdep.h: Formatting. (FUNC_LABEL): Rename from DOT_LABEL. (ENTRY_1): Use FUNC_LABEL and remove leading space from label. Use .p2align rather than .align. (TRACEBACK, TRACEBACK_MASK): Use .p2align rather than .align. (ABORT_TRANSACTION): Likewise. (ENTRY_1, ENTRY_2, END_2, LOCALENTRY): Remove unnecessary semicolons, particularly at end. Add semicolon at invocation as necessary. (TRACEBACK, TRACEBACK_MASK, PSEUDO, PSEUDO_NOERRNO): Likewise. (PSEUDO_ERRVAL, PPC64_LOAD_FUNCPTR, OPD_ENT): Likewise. * sysdeps/powerpc/powerpc64/multiarch/strrchr-power8.S (ENTRY, END): Adjust to suit.
* PowerPC64 FRAME_PARM_SAVEAlan Modra2017-06-143-37/+26
| | | | | | | | | | | | | I think FRAME_PARM[1-9]_SAVE confuse the code, particularly FRAME_PARM9_SAVE. There are only 8 parameter save slots! * sysdeps/powerpc/powerpc64/sysdep.h: (FRAME_BACKCHAIN, FRAME_CR_SAVE, FRAME_LR_SAVE): Move out of conditional. (FRAME_PARM1_SAVE, FRAME_PARM2_SAVE, FRAME_PARM3_SAVE, FRAME_PARM4_SAVE, FRAME_PARM5_SAVE, FRAME_PARM6_SAVE, FRAME_PARM7_SAVE, FRAME_PARM8_SAVE, FRAME_PARM9_SAVE): Delete. * sysdeps/unix/sysv/linux/powerpc/powerpc64/makecontext.S: Replace uses of FRAME_PARM[1-9]_SAVE with FRAME_PARM_SAVE plus offset.
* PowerPC64, fix calls to _mcountAlan Modra2017-06-142-8/+8
| | | | | | | The macros used in assembly were broken on powerpc64 ELFv1. * sysdeps/powerpc/powerpc64/sysdep.h: (call_mcount_parm_offset): Delete. (SAVE_ARG, REST_ARG, CFI_SAVE_ARG): Correct.
* mips: Fix store/load gp registers to/from ucontext_tGordana Cmiljanovic2017-06-137-81/+194
| | | | | | | | | | | | | | | | | | | | | | | | | | General purpose registers in mcontext_t structure are 8 bytes long for both MIPS32/MIPS64. get/set/make/swap context implementations for MIPS O32 incorrectly assume that general purpose registers in this structure are 4 bytes long. This patch is fixing that. Tested for MIPS O32 LE and BE. Compared objdump of modified functions for mips n32 and mips n64. [BZ #21548] * sysdeps/unix/sysv/linux/mips/getcontext.S: Define MCONTEXT_SZGREG as 8 and use it when copying general purpose registers. * sysdeps/unix/sysv/linux/mips/makecontext.S: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/Makefile: Include new test for mips o32. * sysdeps/unix/sysv/linux/mips/mips32/bug-getcontext-mips-gp.c: Added new test for mips o32. * sysdeps/unix/sysv/linux/mips/setcontext.S: Define MCONTEXT_SZGREG as 8 and use it when copying general purpose registers. * sysdeps/unix/sysv/linux/mips/swapcontext.S: Likewise.

| | | | | | | | | | | | | | | | | | <bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from "#include_next" (instead of stdlib/stdlib.h in the glibc source directory), and this turns up as a make dependency. Also make a copy of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h. [BZ #21573] * Makerules [$(c++-bits-std_abs-h) != ""] (before-compile): Add $(common-objpfx)bits/std_abs.h.

* Remove __need_schedparam and __cpu_set_t_defined.Zack Weinberg2017-06-127-243/+163
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bits/sched.h has logic to expose only an impl-namespace variant of struct sched_param (i.e. struct __sched_param), but nothing uses it, and the only header that includes bits/sched.h is sched.h. The __need_schedparam logic can therefore be removed. bits/sched.h also has a great deal of code relating to cpu_set_t objects that was *almost* the same between the two versions of bits/sched.h in the tree; a little spelunking indicated that this is because some bug fixes got applied to the Linux-specific bits/sched.h but not the generic one. Introduce a new header, bits/cpu-set.h, containing the version of that code with the bugfixes, have sched.h include it directly, and delete all of the code from both versions of bits/sched.h. Also remove the unnecessary name mangling in the definition of struct sched_param -- POSIX specifies a field 'sched_priority', so there is no reason to define it as '__sched_priority' and then paper over that with a macro. (Just in case someone was using the internal name, 'sched_priority' remains a macro defined to expand to itself, and '__sched_priority' now expands to 'sched_priority'.) Finally, as long as I'm touching these files anyway, merge new constants from linux/sched.h into the Linux bits/sched.h. * bits/sched.h: Remove __need_schedparam logic and replace with a normal multiple-include guard. Change field name in struct sched_param from __sched_priority to sched_priority. Delete everything under #ifndef __cpu_set_t_defined. * sysdeps/unix/sysv/linux/bits/sched.h: Likewise. Also sync with kernel sched.h, adding SCHED_ISO and SCHED_DEADLINE constants. * posix/sched.h: Include bits/cpu-set.h as well as bits/sched.h. For compatibility, #define sched_priority to itself, and #define __sched_priority as sched_priority. * posix/bits/cpu-set.h: New file containing, verbatim, the code that was under #ifndef __cpu_set_t_defined in sysdeps/unix/sysv/linux/bits/sched.h. * include/bits/cpu-set.h: New wrapper. * posix/Makefile: Install bits/cpu-set.h.

* Allow macros prefixed with FLT128 in include/float.hGabriel F. T. Gomes2017-06-122-16/+21
| | | | | | | | | | | | | | TS 18661-3 specifies that macros prefixed with FLTN_ can be defined in float.h, only if __STDC_WANT_IEC_60559_TYPES_EXT__ is defined as a macro before the inclusion of float.h. Since GCC 7.0, these macros are provided under this condition, however, for older versions of GCC, these macros are not provided at all. This patch allows the definitions of such macros in include/float.h for older compilers, if the condition above is met, and even if _ISOMAC is defined. * include/float.h: Allow the definition of macros prefixed with FLT128 even if _ISOMAC is defined, but provided that __STDC_WANT_IEC_60559_TYPES_EXT__ is defined as a macro.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement strcpy family IFUNC selectors in C. All internal calls within libc.so can use IFUNC on x86-64 since unlike x86, x86-64 supports PC-relative addressing to access the GOT entry so that it can call via PLT without using an extra register. For libc.a, we can't use IFUNC for functions which are called before IFUNC has been initialized. Use IFUNC internally reduces the icache footprint since libc.so and other codes in the process use the same implementations. This patch uses IFUNC for strcpy family functions within libc. * sysdeps/x86_64/multiarch/Makefile (sysdep_routines): Add strcpy-sse2 and stpcpy-sse2. * sysdeps/x86_64/multiarch/ifunc-unaligned-ssse3.h: New file. * sysdeps/x86_64/multiarch/stpcpy-sse2.S: Likewise. * sysdeps/x86_64/multiarch/stpcpy.c: Likewise. * sysdeps/x86_64/multiarch/stpncpy.c: Likewise. * sysdeps/x86_64/multiarch/strcpy-sse2.S: Likewise. * sysdeps/x86_64/multiarch/strcpy.c: Likewise. * sysdeps/x86_64/multiarch/strncpy.c: Likewise. * sysdeps/x86_64/multiarch/stpcpy.S: Removed. * sysdeps/x86_64/multiarch/stpncpy.S: Likewise. * sysdeps/x86_64/multiarch/strcpy.S: Likewise. * sysdeps/x86_64/multiarch/strncpy.S: Likewise. * sysdeps/x86_64/multiarch/stpncpy-c.c (weak_alias): New.

* powerpc: add sysconf support for cache geometriesPaul Clarke2017-06-094-0/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | There is currently no "cross-platform" (x86 and POWER) support for determining the cacheline size. This patch adds support to sysconf() to correctly report cacheline sizes based on the information in the auxilliary vector. Thus, using sysconf() is a cross-platform (x86 and POWER) solution for determining cacheline sizes. Support is added (on powerpc) for: _SC_LEVEL1_ICACHE_SIZE _SC_LEVEL1_ICACHE_ASSOC _SC_LEVEL1_ICACHE_LINESIZE _SC_LEVEL1_DCACHE_SIZE _SC_LEVEL1_DCACHE_ASSOC _SC_LEVEL1_DCACHE_LINESIZE _SC_LEVEL2_CACHE_SIZE _SC_LEVEL2_CACHE_ASSOC _SC_LEVEL2_CACHE_LINESIZE _SC_LEVEL3_CACHE_SIZE _SC_LEVEL3_CACHE_ASSOC _SC_LEVEL3_CACHE_LINESIZE * sysdeps/unix/sysv/linux/powerpc/sysconf.c: New file.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | In sys/wait.h, waitid and associated constants and types are UX-shaded in XPG4.2 (so not in XPG4), and XSI-shaded in POSIX before 2008, so should be appropriately conditional in the headers. This patch fixes the conditionals accordingly. (WCONTINUED is actually still XSI-shaded in POSIX.1:2008, but W* is also reserved there without XSI-shading, so nothing special needs to be done about the conditionals on WCONTINUED to conform to POSIX.1:2008 namespace rules.)

* Update nios2, sparc32 localplt.data files for recent GCC change.Joseph Myers2017-06-093-4/+13
| | | | | | | | | | | | | | | | | | | | | | A recent GCC change to expand floating-point classification built-in functions inline using integer rather than floating-point arithmetic in some cases resulted in localplt test failures for nios2 and sparc32 <https://sourceware.org/ml/libc-testresults/2017-q2/msg00320.html>. This patch updates the localplt.data files in question to mark the relevant symbols as optional / add a new optional symbol. (The GCC patch has been reverted because of other problems it caused, but one can assume it will be applied again, without changes that would affect the PLT entries generated, once those issues have been resolved.)

* Fix sigpause namespace (bug 21554).Joseph Myers2017-06-092-1/+5
| | | | | | | | | | | | The sigpause function is declared for __USE_XOPEN. As it's new in XPG4.2 it should be declared only for __USE_XOPEN_EXTENDED. This patch fixes the declaration accordingly. Tested for x86_64. [BZ #21554] * signal/signal.h (sigpause):: Declare if [__USE_XOPEN_EXTENDED], not [__USE_XOPEN].
* Condition signal.h inclusion in sys/wait.h (bug 21560).Joseph Myers2017-06-092-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | sys/wait.h includes signal.h unconditionally. But the permission to do so is UX-shaded in XPG4.2, and XSI-shaded in POSIX before 2008, so this should not be unconditional. This patch fixes this conservatively: the include is kept, but conditioned on the standards that permit it (meaning it is still present by default, because non-XSI POSIX.1:2008 is enabled by default). <bits/types.h> is now included unconditionally to provide the required definition of __pid_t; it was previously included via <signal.h>. Some standards require pid_t to be defined here, and all allow it to be defined here; previously defined via <signal.h>, it's now defined directly in this header. Tested for x86_64. This does not fix any of the sys/wait.h conformtest failures, but substantially reduces the number of namespace failures for sys/wait.h for XPG4 and POSIX. [BZ #21560] * posix/sys/wait.h: Condition include of <signal.h> on [__USE_XOPEN_EXTENDED || __USE_XOPEN2K8]. Include <bits/types.h> unconditionally. [!__pid_t_defined] (pid_t): Define typedef.

(common-generated): Add libc-modules.h and libc-modules.stmp in a more appropriate location. Also add dl-tunable-list.h and dl-tunable-list.stmp.

* Refactor PRINT_FPHEX_LONG_DOUBLE into a reusable macroGabriel F. T. Gomes2017-06-073-85/+116
| | | | | | | | | | | | | | This patch refactors the macro PRINT_FPHEX_LONG_DOUBLE from the file sysdeps/ieee754/ldbl-128/printf_fphex.c into a function-like macro to enable its use for both long double and _Float128, when they are ABI-distinct. * sysdeps/ieee754/ldbl-128/printf_fphex.c: Include ldbl-128/printf_fphex_macros.h for the definition of PRINT_FPHEX. (PRINT_FPHEX_LONG_DOUBLE): Define based on PRINT_FPHEX. * sysdeps/ieee754/ldbl-128/printf_fphex_macros.h (PRINT_FPHEX): New function-like macro that can be used for long double, as well as for _Float128
* Remove duplicated code from __printf_fp_l, __printf_fphex, and __printf_sizeGabriel F. T. Gomes2017-06-074-199/+125
| | | | | | | | | | | | | | | | | | | In __printf_fp_l, __printf_fphex, and __printf_size the blocks of code that are used to read a double or long double argument, check for special values and convert to multiprecision are similar. When adding float128 support to libc, more code would be duplicated to deal with the extra type. This patch moves the repetitive code to a macro which is now used by double and long double and will be used for float128 when support is added, thus avoiding more duplication. Tested for powerpc64le and s390x. * stdio-common/printf_fp.c (PRINTF_FP_FETCH): New macro. (__printf_fp_l): Use the new macro to avoid duplicating code. * stdio-common/printf_fphex.c (PRINTF_FPHEX_FETCH): New macro. (__printf_fphex): Use the new macro to avoid duplicating code. * stdio-common/printf_size.c (PRINTF_SIZE_FETCH): New macro. (__printf_size): Use the new macro to avoid duplicating code.
