5a4eb7282e Remove ENABLE_SSSE3_ON_ATOM. 
It turns that SSSE3 isn't slow on Atom. The problem is bsf. This patch
removes ENABLE_SSSE3_ON_ATOM.

02cea47161 Add x86 32-bit SSE4.2 string functions. 
This patch adds 32bit SSE4.2 string functions.  It uses -16L instead of
0xfffffffffffffff0L, which works for both 32bit and 64bit long.  Tested
on 32bit Core i7 and Core 2.

6f6f1215f6 Support multiarch for i686. 
This patch adds multiarch support when configured for i686.  I modified
some x86-64 functions to support 32bit. I will contribute 32bit SSE string
and memory functions later.

da97dfdcfa Add sigstack handling to Linux ____longjmp_chk on i386.

06e51c8f3d Add SSE4.2 support for strcspn, strpbrk, and strspn on x86-64. 2009-07-03 02:48:56 -07:00

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.

fd96f06208 Small optimization of STT_GNU_IFUNC handling. 
The test to call the indirect function now includes a subtest to
checked whether the symbol is defined.  When coming to that point
this is almost always the case.  The test for STT_GNU_IFUNC on the
other hand rarely is true.  Move it to the front means we don't have
to perform the second test unless really necessary.

b50f8e42ba Check for valid stack frame in longjmp. 
If longjmp restores the stack frame to an address which is beyond
the stack frame at the time of the longjmp call it would install
an uninitialized stack frame.  If compiled with _FORTIFY_SOURCE
defined, longjmp will now bail out in this situation.
