2015-09-08Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912).Joseph Myers31-39/+179
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/libc-lock.h to plain libc-lock.h and bits/libc-lockP.h to plain libc-lockP.h to follow that convention. Note that I don't know where libc-lockP.h comes from for Hurd (the Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in the glibc source tree is for NPTL) - some unmerged patch? - but I updated the #include in the Hurd libc-lock.h anyway. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #14912] * bits/libc-lock.h: Move to ... * sysdeps/generic/libc-lock.h: ...here.

2015-09-08MIPS: Only use .set mips* assembler directives when necessaryAndrew Bennett5-23/+40
There are a few .set mips* assembler directives used in the MIPS specific sysdep code that force an instruction to be assembled for a specific ISA. The reason for these is to allow an instruction to be encoded when it might not be supported in the current ISA (when the code is run the Linux kernel will trap and emulate any unsupported instructions). Unfortunately forcing a specific ISA means that when assembling for a newer ISA, where the instruction has a different encoding, the wrong encoding will be used. * sysdeps/mips/bits/atomic.h [_MIPS_SIM == _ABIO32] (MIPS_PUSH_MIPS2): Only use .set mips2 if the current ISA is below mips2. * sysdeps/mips/sys/tas.h [_MIPS_SIM == _ABIO32] (_test_and_set): Likewise. * sysdeps/mips/nptl/tls.h (READ_THREAD_POINTER): Only use .set mips32r2 if the current ISA is below mips32r2. * sysdeps/mips/tls-macros.h (TLS_RDHWR): New define. (TLS_IE): Updated to use the TLD_RDHWR macro. (TLS_LE): Likewise. * sysdeps/unix/mips/sysdep.h (__mips_isa_rev): Moved out of #ifdef __ASSEMBLER__ condition.

This patch adds new constants from Linux 4.2 to netinet/in.h: IPPROTO_MPLS and IP_BIND_ADDRESS_NO_PORT (both in include/uapi/linux/in.h in Linux; one directly in netinet/in.h, one in bits/in.h in glibc).

2015-08-28Fix wordsize-32 mmap offset for negative value (BZ#18877)Adhemerval Zanella1-4/+4
This patch fixes the default wordsize-32 mmap implementation offset calculation for negative values. Current code uses signed shift operation to calculate the multiple size to use with syscall and it is implementation defined. Change it to use a division base on mmap page size (default being as before, 4096). Tested on armv7hf. [BZ #18877] * posix/Makefile (tests): Add tst-mmap-offset. * posix/tst-mmap.c: New file. * sysdeps/unix/sysv/linux/generic/wordsize-32/mmap.c (__mmap): Fix offset calculation for negative values.
2015-08-27Detect and select i586/i686 implementation at run-timefedora/masterH.J. Lu6-3/+95
We detect i586 and i686 features at run-time by checking CX8 and CMOV CPUID features bits. We can use these information to select the best implementation in ix86 multiarch. HAS_I586/HAS_I686 is true if i586/i686 instructions are available on the processor. Due to the reordering and the other nifty extensions in i686, it is not really good to use heavily i586 optimized code on an i686. It's better to use i486 code if it isn't an i586. USE_I586/USE_I686 is true if i586/i686 implementation should be used for the processor. USE_I586 is true only if i686 instructions aren't available. If i686 instructions are available, we always choose i686 or i486 implementation, in that order, and we never choose i586 implementation for i686-class processors. * sysdeps/i386/init-arch.h: New file. * sysdeps/i386/i586/init-arch.h: Likewise. * sysdeps/i386/i686/init-arch.h: Likewise. * sysdeps/x86/cpu-features.c (init_cpu_features): Set bit_I586 bit if CX8 is available.

This patch adds that bit to sysdeps/powerpc/bits/hwcap.h. 2015-08-26 Carlos Eduardo Seo <cseo@linux.vnet.ibm.com> * sysdeps/powerpc/bits/hwcap.h: Add PPC_FEATURE2_HTM_NOSC. * sysdeps/powerpc/dl-procinfo.c: (_dl_powerpc_cap_flags): Added descriptor for this hwcap feature so it shows when LD_SHOW_AUXV=1.
2015-08-26powerpc: Revert to default atomic ops in elision codePaul E. Murphy1-21/+0
Power ISA 2.07B section B.5.5 relaxed the barrier requirement around a TLE enabled lock. It is now identical to a traditional lock. 2015-08-26 Paul E. Murphy <murphyp@linux.vnet.ibm.com> * sysdeps/unix/sysv/linux/powerpc/elision-lock.c (__arch_compare_and_exchange_val_32_acq): Remove and use common definition. ISA 2.07B no longer requires full sync.
2015-08-26mips: siginfo.h: add SIGSYS details [BZ #18863]Mike Frysinger1-0/+11

2015-08-26Replace BZERO_P/PIC with USE_AS_BZERO/SHAREDH.J. Lu4-24/+20
Replace BZERO_P with USE_AS_BZERO in i586/i686 memset.S to support i386 multi-arch memset. Also we should check SHARED not PIC for libc.so since libc.a may be compiled with PIC. * sysdeps/i386/i586/bzero.S (USE_AS_BZERO): New. * sysdeps/i386/i686/bzero.S (USE_AS_BZERO): Likewise. * sysdeps/i386/i586/memset.S (BZERO_P): Removed. Check USE_AS_BZERO/SHARED instead of BZERO_P/PIC. (__memset_zero_constant_len_parameter): New. * sysdeps/i386/i686/memset.S (BZERO_P): Removed. Check USE_AS_BZERO/SHARED instead of BZERO_P/PIC. (__memset_zero_constant_len_parameter): Don't define if __memset_chk or USE_AS_BZERO are defined.
2015-08-26Replace MEMPCPY_P/PIC with USE_AS_MEMPCPY/SHAREDH.J. Lu2-8/+4
Replace MEMPCPY_P with USE_AS_MEMPCPY in i586 memcpy.S to support i386 multi-arch memcpy.

2015-08-26Don't disable SSE in x86-64 ld.soH.J. Lu4-12/+19
Since x86-64 ld.so preserves vector registers now, we can use SSE in x86-64 ld.so. We should run tst-ld-sse-use.sh only on i386. * sysdeps/x86/Makefile [$(subdir) == elf] (CFLAGS-.os, tests-special, $(objpfx)tst-ld-sse-use.out): Moved to ... * sysdeps/i386/Makefile [$(subdir) == elf] (CFLAGS-.os, tests-special, $(objpfx)tst-ld-sse-use.out): Here. Update comments. * sysdeps/x86_64/Makefile [$(subdir) == elf] (CFLAGS-.os): Add -mno-mmx for $(all-rtld-routines). * sysdeps/x86/tst-ld-sse-use.sh: Moved to ... * sysdeps/i386/tst-ld-sse-use.sh: Here. Replace x86-64 with i386.
2015-08-26Adjust _Unwind_Word in unwind.h to version in libgcc.Stefan Liebler1-2/+2
Building glibc on s390-32 with gcc option -mzarch produces the error due to sysdeps/s390/jmpbuf-unwind.h:37:10: (void *) (_Unwind_GetCFA (_context): cast to pointer from integer of different size [-Werror=int-to-pointer-cast] Building on s390-32 in esa-mode or s390-64 is fine. _Unwind_GetCFA returns an _Unwind_Word which is an unsigned with a size of 4 bytes on s390-32 (esa-mode) and 8 bytes on s390-64. On s390-32 (zarch-mode), _Unwind_Word has a size of 8 bytes, too. _Unwind_Word is defined in sysdeps/generic/unwind.h as typedef unsigned _Unwind_Word __attribute__((__mode__(__word__))); In libgcc unwind header (<gcc-src>/libgcc/unwind-generic.h) this typedef has changed to "typedef unsigned _Unwind_Word __attribute__((__mode__(__unwind_word__)));" in June 2008. With this mode, _Unwind_Word has a size of 4 bytes on s390-32 (zarch-mode). The same change applies to _Unwind_Sword. Thus this patch updates the unwind header according to these changes. Afterwards, the int-to-pointer-cast-warning is gone away on s390-32 (zarch-mode) and the testsuite runs with the same test-failures as s390-32 (esa-mode) plus FAIL: c++-types-check. Here register_t is expected to has a size of 4 bytes, but it has a size of 8 bytes due to: posix/sys/types.h:205:typedef int register_t __attribute__ ((__mode__ (__word__))); The libgcc-patch for gcc 4.4 can be found here: "[PATCH, spu, unwind] Remove attribute ((mode (word))) from unwind.h" https://gcc.gnu.org/ml/gcc-patches/2008-06/msg00969.html ChangeLog: * sysdeps/generic/unwind.h (_Unwind_Word): Use __mode__(__unwind_word__) instead of __mode__(__word__). (_Unwind_Sword): Likewise.
2015-08-26S390: Fix build error with gcc6 in utf8_utf16-z9.c.Stefan Liebler1-0/+2
This patch fixes the build error with gcc6: array subscript is above array bounds [-Werror=array-bounds] While including loop.c to construct the SINGLE(LOOPFCT) method for converting from UTF-16 to UTF-8, the bytebuf array with length MAX_NEEDED_INPUT is used as inptr. MAX_NEEDED_INPUT defaults to MIN_NEEDED_INPUT if not defined before including loop.c. Thus bytebuf has a length of 2. This patch defines MAX_NEEDED_INPUT to MAX_NEEDED_TO, which is 4. ChangeLog: * sysdeps/s390/s390-64/utf8-utf16-z9.c (MAX_NEEDED_INPUT): New define. (MAX_NEEDED_OUTPUT): New define.
