Ulrich Drepper 889f847e4a Define NT_GNU_GOLD_VERSION. 2009-07-26 08:26:43 -07:00
H.J. Lu 4e5b5821bf Some some optimizations for x86-64 strcmp. 2009-07-25 19:15:14 -07:00
Ulrich Drepper 657317537c Handle missing NSS modules and those without callbacks. 
getaddrinfo didn't update the status variable in that round of the
loop if no callback was used.

Ulrich Drepper 29e92fa5cd Optimize x86-64 SSE4.2 strcmp. 
The file contained some code which was never used.  Don't compile it
in.

Ulrich Drepper da331e8e14 Don't automatically use /lib/modules/* headers. 
Ever since the /usr/include/linux headers got cleaned up this isn't
necessary.  Meanwhile everybody should have these cleanups.

Andreas Krebbel f957edded8 S/390: Hardware iconv modules. 2009-07-24 08:29:06 -07:00
Ulrich Drepper 01b597da40 Check for .cfi_{personality,lsda} on x86-64. 
We need this support in NPTL now to avoid the hand-coded tables.
 2009-07-23 17:15:56 -07:00
Ulrich Drepper f1adf1f490 Fix pthread_cond_timedwait error handling on old kernels. 2009-07-23 16:39:06 -07:00
Ulrich Drepper b2509a1e38 Avoid cpuid instructions in cache info discovery. 
When multiarch is enabled we have this information stored.  Use it.
 2009-07-23 14:03:53 -07:00
Ulrich Drepper 3e9099b4f6 Add more cache descriptors for L3 caches on x86 and x86-64. 
The most recent AP 485 describes a few more cache descriptors for
L3 caches with 24-way associativity.
 2009-07-23 13:42:46 -07:00
Ulrich Drepper d28797e426 Perform test for Arom x86-64 in central place and handle it. 
There will be more than one function which, in multiarch mode, wants
to use SSSE3.  We should not test in each of them for Atoms with
slow SSSE3.  Instead, disable the SSSE3 bit in the startup code for
such machines.

Ulrich Drepper 666a9871f7 Avoid warnings in test cases. 
The posix/tst-rfc3484* test cases caused warnings in newer gccs
because the unused but copied sin_zero part of sockaddr_in wasn't
explicitly initialized.

Duncan Simpson 30a2dfd518 Make include/unistd.h suitable for C++ test cases. 2009-07-23 12:39:17 -07:00
Ulrich Drepper 9b6bf8a302 Preserve stack alignment in i386 makecontext. 2009-07-23 08:02:07 -07:00
Ulrich Drepper c15b1d20cd Minor optimization of unloading prevention patch. 
References to unique symbols from copy relocations can only come
from executables which cannot be unloaded anyway.  Optimize the
code to set the unload flag a bit.
 2009-07-23 07:40:56 -07:00
Ulrich Drepper fe4d2935e8 Fix comment. 2009-07-23 07:37:48 -07:00
Ulrich Drepper 077e7700b3 Some more fixes for the unique symbol handling. 
The hash value can be zero, so we need a different test for empty
slots.  And unify the way we prevent a DSO from being unloaded.
 2009-07-23 07:36:34 -07:00
Ulrich Drepper 802fe9a1ca Handle unloading of DSO with a unique symbol definition. 2009-07-23 07:07:53 -07:00

Ulrich Drepper ae612b04cc Minor cleanups in x86-64 strstr. 2009-07-21 07:52:12 -07:00
Ulrich Drepper a8f895ebe1 Better check for optimization in new x86-64 strstr/strcasestr. 2009-07-20 21:18:28 -07:00
H.J. Lu 2b7a8664fa SSE4.2 strstr/strcasestr for x86-64. 
This patch implements SSE4.2 strstr/strcasestr, using Knuth-Morris-Pratt
string searching algorithm.

Ulrich Drepper 63fbc91bec Use correct index for _NL_CTYPE_NONASCII_CASE. 2009-07-20 20:50:38 -07:00
Ulrich Drepper 8a4494506d Check generated locale for non-ASCII 8-bit characters with case conversion. 
If a locale does not have 8-bit characters with case conversion which
are different from the ASCII conversion (±0x20) then we can perform
some optimizations.  These will follow later.

Ulrich Drepper c3db953c16 Minor optimizations of last x86-64 condvar changes. 2009-07-20 08:39:47 -07:00
Ulrich Drepper 42e69bcf11 Support requeueing for condvars using PI mutex. x86-64 only. 
Add support for the new FUTEX_WAIT_REQUEUE_PI and FUTEX_CMP_REQUEUE_PI
options of futex.
 2009-07-19 20:56:40 -07:00
Ulrich Drepper 515a8908ce Make x86-64 pthread_cond_timedwait more robust. 
It just happens that __pthread_enable_asynccancel doesn't modify the $rdi
register.  But this isn't guaranteed.  Hence we reload the register after
the calls.

Ulrich Drepper 92618c954f Optimize x86-64 pthread_cond_timedwait. 
Instead of actively registering an unwind buffer we now use the
exception handling functionality of the gcc runtime.

Ulrich Drepper 09f97a8fbf Add missing BZ number in ChangeLog. 2009-07-17 05:58:12 -07:00
Ulrich Drepper 1c0ab5bd34 Handle overly large answer buffers in resolver. 
In EDNS0 records the maximum result size is transmitted in a 16
bit value.  Large buffer sizes were handled incorrectly by using
only the low 16 bits.  Fix this by limiting the size to 0xffff.

Petr Baudis 137028b4d7 Fix lock handling in memory hander of nscd. 
The commit 20e498bd removes the pthread_mutex_rdlock() calls, but not the
corresponding pthread_mutex_unlock() calls. Also, the database lock is never
unlocked in one branch of the mempool_alloc() if.

I think unreproducible random assert(dh->usable) crashes in prune_cache() were
caused by this. But an easy way to make nscd threads hang with the broken
locking was.
