* Update comments in ldconfig.c and dl-hwcaps.c.Carlos O'Donell2013-05-223-8/+16
| | | | | | | | | | | | | | | | | In dl-hwcaps.c the comment read that rounding was done to ElfW(Addr), but it's actually rounded to ElfW(Word). In ldconfig.c we make each comment a sentence and mention that the "tls" pseudo-hwcap is just for legacy installations where TLS was optional. --- 2013-05-22 Carlos O'Donell <carlos@redhat.com> * elf/ldconfig.c (is_hwcap_platform): Make comments full setences. (main): Mention "tls" pseudo-hwcap is legacy. * elf/dl-hwcaps.c (_dl_important_hwcaps): Correct rounding comment.
* Don't include function names in test data in generated libm-test.c.Joseph Myers2013-05-223-132/+327

* Update bits/siginfo.h with Linux hwpoison SIGBUS changesEdjunior Barbosa Machado2013-05-2212-8/+89
| | | | | | Adds new SIGBUS error codes for hardware poison signals, syncing with the current kernel headers (v3.9). It also adds si_trapno field for alpha.
* Fix _nl_find_msg malloc failure case, and callers.Carlos O'Donell2013-05-224-7/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes two issues, and perhaps should be two distinct commits, but I present it here as one for the sake of completeness. Commit 006dd86111c44572dbd3b26e9c63dd0f834d7762 fails to check malloc's return in intl/dcigettext.c (_nl_find_msg): ~~~ freemem_size = INITIAL_BLOCK_SIZE; newmem = (transmem_block_t *) malloc (freemem_size); ... newmem->next = transmem_list; transmem_list = newmem; ~~~ If malloc fails then newmem is NULL then newmem->next results in a fault. The fix is easy enough, check for newmem != NULL, and fall through to the error condition below which returns (char *) -1 e.g. resource error. The problem is that returning (char *) -1 will break all sorts of other code, so while what we did is correct, the real failure case fix is slightly broader. There are 4 other places where _nl_find_msg is called, one is OK, the other three are fixed to handle -1 error return value. No regressions on x86-64 or x86. However, no regressions isn't really a useful metric for this code. The change was tested as documented here: http://sourceware.org/glibc/wiki/Testing/WhiteBox using SystemTap for fault injection to simulate malloc failure. --- 2013-05-03 Carlos O'Donell <carlos at redhat.com> [BZ #15441] * intl/dcigettext.c (DCIGETTEXT): Skip translating if _nl_find_msg returns -1. (_nl_find_msg): Return -1 if recursive call returned -1. If newmem is null return -1. * intl/loadmsgcat.c (_nl_load_domain): If _nl_find_msg returns -1 abort loading the domain.

* Test getaddrinfo return valueDmitry V. Levin2013-05-213-1/+74
| | | | | | This helps testing for regression of BZ#15339. Creation of network isolated environments is a privileged operation and therefore is not included to the test.
* Set EAI_SYSTEM only when h_errno is NETDB_INTERNALSiddhesh Poyarekar2013-05-214-10/+26
| | | | | | | | | | | | Fixes BZ #15339. NSS_STATUS_UNAVAIL may mean that a necessary input resource is not available. This could occur in a number of cases including when the network is down, system runs out of file descriptors, etc. The correct differentiator in such a case is the h_errno, which gives the nature of failure. In case of failures other than a simple 'not found', we set h_errno as NETDB_INTERNAL and let errno be the identifier for the exact error.

| | | | | | Update ChangLog bugzilla number and NEWS for commit 13d3b41a36c4f28d171a144f8a9baad3a8835981 (PowerPC: fix hypot/hypotf check for -INF).
* Faster memset on x64Ondrej Bilka2013-05-202-1315/+96
| | | | | | | | | This implementation speed up memset in several ways. First is avoiding expensive computed jump. Second is using fact that arguments of memset are most of time aligned to 8 bytes. Benchmark results on: kam.mff.cuni.cz/~ondra/benchmark_string/memset_profile_result27_04_13.tar.bz2
* Faster memcpy on x64.Ondrej Bilka2013-05-205-8/+195
| | | | | | | | | We add new memcpy version that uses unaligned loads which are fast on modern processors. This allows second improvement which is avoiding computed jump which is relatively expensive operation. Tests available here: http://kam.mff.cuni.cz/~ondra/memcpy_profile_result27_04_13.tar.bz2

* Prevent optimizing out of benchmark function callSiddhesh Poyarekar2013-05-174-3/+10
| | | | | | | | | | Resolves: #15424 The compiler would optimize the benchmark function call out of the loop and call it only once, resulting in blazingly fast times for some benchmarks (notably atan, sin and cos). Mark the inputs as volatile so that the code is forced to read again from the input for each iteration.

* MIPS: soft-fp NaN representation correctionsMaciej W. Rozycki2013-05-1615-18/+124
| | | | | | | | [BZ #15442] This adds support for the inverse interpretation of the quiet bit of IEEE 754 floating-point NaN data that some processors use. This includes in particular MIPS architecture processors; the payload used for the canonical qNaN encoding is updated accordingly so as not to interfere with the quiet bit.

* hppa: Cleanup libm-test-ulps.Carlos O'Donell2013-05-152-420/+3
| | | | | | | | | | | | | | | | Joseph Myers noted that there were several old and really very incorrect values in the hppa libm-test-ulps. This patch removes all of the ulps values for ceil, floor, rint, round, trun, llrint, and llround, all of which were previously incorreclty added (including some negative values which are really wrong). --- ports/ 2013-05-15 Carlos O'Donell <carlos@redhat.com> * sysdeps/hppa/fpu/libm-test-ulps: Remove old values for ceil, floor, rint, round, trunc, llrint, and llround.

* Use movq for 64-bit operationsPeter Collingbourne2013-05-152-2/+8
| | | | | | | | | | | The EXTRACT_WORDS64 and INSERT_WORDS64 macros use movd for a 64-bit operation. Somehow gcc manages to turn this into movq, but LLVM won't. 2013-05-15 Peter Collingbourne <pcc@google.com> * sysdeps/x86_64/fpu/math_private.h (MOVQ): New macro. (EXTRACT_WORDS64) Use where appropriate. (INSERT_WORDS64) Likewise.
* Use x constraints for operands to vfmaddss and vfmaddsdPeter Collingbourne2013-05-153-2/+6
| | | | | | | | | | | | | | | While these instructions accept memory operands, only one operand may be a memory operand. Giving two operands xm constraints gives the compiler the option of using memory for both operands, which would result in invalid assembly code. Using x for all operands is more appropriate, as most x86_64 calling conventions will pass the arguments in registers anyway. 2013-05-15 Peter Collingbourne <pcc@google.com> * sysdeps/x86_64/fpu/multiarch/s_fma.c (__fma_fma4): Replace xm constraints with x constraints. * sysdeps/x86_64/fpu/multiarch/s_fmaf.c (__fmaf_fma4): Likewise.
* Move _obstack_compat out of commonPeter Collingbourne2013-05-152-1/+5
| | | | | | | | | | | | | it is impossible to create an alias of a common symbol (as compat_symbol does), because common symbols do not have a section or an offset until linked. GNU as tolerates aliases of common symbols by simply creating another common symbol, but other assemblers (notably LLVM's integrated assembler) are less tolerant. 2013-05-15 Peter Collingbourne <pcc@google.com> * malloc/obstack.c (_obstack_compat): Add initializer. -
* Reserve new TLS field for x86 and x86_64Andreas Jaeger2013-05-154-11/+21
| | | | | | | [BZ #10686] * sysdeps/x86_64/tls.h (struct tcbhead_t): Add __private_ss field. * sysdeps/i386/tls.h (struct tcbhead_t): Likewise.
