ff9f1c5f32 Fix DL_DEBUG_UNUSED to elide the VDSO and handle PLT references properly. 
* elf/rtld.c (dl_main): If DL_DEBUG_UNUSED is enabled, turn off
	lazy binding.
	* elf/dl-lookup (_dl_lookup_symbol_x): If DL_DEBUG_UNUSED, ignore
	undefined symbol errors.

	* elf/rtlc.c (dl_main): Skip VDSO when checking for unused
	DT_NEEDED entries.

e80d6f94e1 Fix size parameter comparisions. 
[BZ #13592]
There are several signed compares of the size argument, whereas
it really is unsigned.  Depending on situations e.g. a "memset(ptr, 0,
-1)" segfault (but for the wrong reasons, because jumping into nirvana)
or succeeds even.

In normal use this is harmless, as a size with signbit set indicates
more than half the address space which on x86_64 is impossible to
allocate, but as the size is used to index some jump tables this
potentially could have other unwanted side effects.

349fa79f55 Don't warn about unused result of mktemp 
[BZ #13908]
    mktemp always returns TEMPLATE, the caller should check TEMPLATE[0]
    instead of TEMPLATE, so do not warn about the unused result.
    Fix also the comment for mktemp

b1aa60f32d Add __bswap_64 definition for non GCC compilers. 
[BZ#13926]
Currently __bswap_64 is not defined at all for non-GCC compilers.
Define it but guard it with __GLIBC_HAVE_LONG_LONG.

endian.h uses __bswap_64, make the functions only available
if __GLIBC_HAVE_LONG_LONG is defined.

135ffda8b8 Tighten up vfprintf width, precision, and total length overflow handling. 
With help from Paul Eggert, Carlos O'Donell, and Roland McGrath.
	* stdio-common/printf-parse.h (read_int): Change return type to
	'int', return -1 on INT_MAX overflow.
	* stdio-common/vfprintf.c (vfprintf): Validate width and precision
	against overflow of INT_MAX.  Set errno to EOVERFLOW when 'done'
	overflows INT_MAX.  Check for overflow of in-format-string precision
	values properly.  Use EOVERFLOW rather than ERANGE throughout.  Use
	SIZE_MAX not INT_MAX for integer overflow test.
	* stdio-common/printf-parsemb.c: If read_int signals an overflow,
	skip the construct in the format string but do not record anything.
	* stdio-common/bug22.c: Adjust to test both width/prevision
	INT_MAX overflow as well as total length INT_MAX overflow.  Check
	explicitly for proper errno values.

4b43400f6a optimize the following memcpy: sysdeps/i386/i686/multiarch/memcpy-ssse3.S 
I've improved the following implementation of memcpy:
"sysdeps/i386/i686/multiarch/memcpy-ssse3.S".

The patch includes some minor style fixes, but the important part is
just using prefetch loops for the case:

DATA_CACHE_SIZE_HALF <= len <  SHARED_CACHE_SIZE_HALF and
src and dst pointers have unequal 16 byte alignments.

This gives from 6% - 50% performance boost on the atom machine, about
24,73% in geometric mean.

48c41d04ee Consider TTL of CNAME record and return minimum TTL in the chain 
[BZ #13928] A DNS request consists of multiple resources combined into
a single hostent, including multiple CNAME records that may have been
assigned different TTL values. In such a case, nscd should take the
least TTL among all of the resources as the timeout for the hostent
before it is reloaded in its cache so that the hostent remains stale
in the database for the least amount of time.

d0adc92230 i386/x86_64: Optimize feholdexcept. 2012-03-19 06:51:06 -07:00
Richard Henderson
0fe0f1f86f Create and use libc_feupdateenv_test. 
We can reduce the number of STMXCSR, and often we can avoid the
call to __feraiseexcept.

eb92c487b3 Create and use SET_RESTORE_ROUND{,_NOEX,_53BIT}{,F,L}. 2012-03-19 06:49:44 -07:00
Richard Henderson
7d2e8012cf i386: Convert libc_{feholdexcept_setround,updateenv}_53bit to functions. 
Also fix a bug in libc_feupdateenv_53bit: don't force the rounding
precision back to _FPU_EXTENDED, instead restore the precision that
the user had in effect beforehand.

b4dabbb47a Convert libc_feholdexcept et al from macros to inline functions. 2012-03-19 06:48:27 -07:00
Richard Henderson
4851a949b4 Make inline __isnan, __isinf_ns, __finite generic. 
For code generation to stay identical on x86_64, this requires that
we define the fp word manipulation macros before including the
generic header.
