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.
 2009-07-25 12:29:04 -07:00
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 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 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.
 2009-07-20 21:06:50 -07:00
Ulrich Drepper 63601ccd16 Replace hand-coded unwind tables from x86-64 pthread_once. 2009-07-17 14:45:08 -07:00
Ulrich Drepper 55c4ce6885 Remove warning and little optimization. 
The prototype for _dl_higher_prime_number was missing.  While at it,
the function is now marked with internal_function.
 2009-07-16 07:18:53 -07:00
Ulrich Drepper c8027cced1 Optimize restoring of ymm registers on x86-64. 
The patch mainly reduces the code size but also avoids some jumps.
 2009-07-16 07:15:15 -07:00
Ulrich Drepper 24a12a5a5f Fix up whitespaces in new memcmp for x86-64. 2009-07-16 07:02:27 -07:00
H.J. Lu e26c9b8415 memcmp implementation for x86-64 using SSE2. 2009-07-16 07:00:34 -07:00
Ulrich Drepper ca419225a3 Fix thinko in AVX audit patch. 
Don't use AVX instructions too often.
 2009-07-15 17:59:14 -07:00
Ulrich Drepper 47fc9b710b Fix typo in last change. 2009-07-15 17:51:11 -07:00
Ulrich Drepper d7bd7a8ae8 Secure AVX changes for auditing code. 
The original AVX patch used a function pointer to handle the difference
between machines with and without AVX support.  This is insecure.  A
well-placed memory exploit could lead to redirection of the execution.
Using a variable and several tests is a bit slower but cannot be
exploited in this way.
 2009-07-15 17:41:36 -07:00
H.J. Lu b0ecde3a63 Add AVX support to ld.so auditing for x86-64. 2009-07-10 12:04:14 -07:00
Ulrich Drepper 339717d5f1 Fix comment in Linux's <sys/epoll.h>. 2009-07-10 06:14:25 -07:00
Ulrich Drepper 415ac3df9b Implement STB_GNU_UNIQUE handling. 
Some symbols have to be identified process-wide by their name.  This is
particularly important for some C++ features (e.g., class local static data
and static variables in inline functions).  This cannot completely be
implemented with ELF functionality so far.  The STB_GNU_UNIQUE binding
helps by ensuring the dynamic linker will always use the same definition for
all symbols with the same name and this binding.

Andreas Schwab 2123d5815e Fix wrong PPC_FEATURE_* values. 
Nothing uses these wrong values yet, but it fixes a warning due to
conflicting definitions in <asm/cputable.h>.
 2009-07-05 23:46:03 -07:00
Ulrich Drepper cea4329592 Minor cleanups in recently added files. 2009-07-03 03:23:01 -07:00
Ulrich Drepper d6485c981b Align functions to 16-byte boundary. 
Some of the new multi-arch string functions for x86-64 were
not aligned to 16 byte boundarie,s possibly creating unnecessary
cache line misses and delays.
 2009-07-03 03:01:57 -07:00
H.J. Lu 06e51c8f3d Add SSE4.2 support for strcspn, strpbrk, and strspn on x86-64. 2009-07-03 02:48:56 -07:00
H.J. Lu 167d5ed5de Fix handling of xmm6 in ld.so audit hooks on x86-64. 2009-07-02 04:33:12 -07:00

H.J. Lu ab6a873fe0 SSSE3 strcpy/stpcpy for x86-64 
This patch adds SSSE3 strcpy/stpcpy. I got up to 4X speed up on Core 2
and Core i7.  I disabled it on Atom since SSSE3 version is slower for
shorter (<64byte) data.

Ulrich Drepper e6bd12ddf7 Regenerated. 2009-06-30 05:33:52 -07:00

Andreas Schwab 80a98966c8 Fix text relocation on ppc32. 
The ____longjmp_chk implementation didn't load from memory the
right way.

Andreas Schwab f60ddf9bf7 Don't treat bug reporting message as a format string. 2009-06-16 20:34:55 -07:00
Ulrich Drepper f793b62438 Extend pt_chown to drop privileges. 
If libcap is available, use it to drop privileges in pt_chown before
starting the work to change the permissions and ownership of the
slave device.

Ryan S. Arnold 25bfbb9e0e Fix incorrect use of cmpldi in 32-bit PPC code. 
The 32-bit PowerPC POWER6 memcpy uses the cmpldi insn when it should use a cmplwi.

Ulrich Drepper 292e3abebf Fix permission of slave device on devpts if necessary. 
If devptr is misconfigured the slave device permission after grantpt
might not be 0620.  BZ #10166

Ulrich Drepper 48dcd0ba84 Preserve message printed before abort. 
The terminal output etc is not visible in a core file.  The new
libc-internal variable __abort_msg will point to a string with the
message which has been printed before the abort in case abort is
called from inside libc.  BZ #10217
 2009-06-15 16:17:09 -07:00
Jakub Jelinek 0212596218 libc part of prelink IFUNC support. 
The dl-lookup.c changes are needed for prelink (support in prelink
checked into SVN, tested for both i?86 and x86-64), dl-irel.h just
something I discovered by code inspection.
