add_temp_file now makes a copy which is freed by delete_temp_files.
Callers to create_temp_file can now free the returned file name to
avoid the memory leak. These changes do not affect the leak behavior
of existing code.
Also address a NULL pointer derefence in tzset after a memoru allocation
failure, found during testing.
-Winline causes architecture- and optimization-dependent build failures
due to -Werror. -Winline warns about inlining decisions based on
branch hints, in effect preventing the use of inline functions in
header files (because they might be called on unlikely branches, leading
to a decision not to inline).
The option was apparently added to the glibc build at a time when GCC
did not support the always_inline attribute. With current GCC versions,
inlining failure for functions declared always_inline will receive a
warning under -Wattributes, which is enabled by default, so -Winline
appears unnecessary.
This patch adds support to query cache information on s390
via sysconf() function - e.g. with _SC_LEVEL1_ICACHE_SIZE.
The attributes size, linesize and assoc can be queried
for cache level 1 - 4 via "extract cpu attribute" instruction,
which was first available with z10.
* NEWS: Mention sysconf() cache information support for s390.
* sysdeps/unix/sysv/linux/s390/sysconf.c: New File.
* stdlib/setenv.c (__add_to_environ):
Dump core quickly if setenv (..., NULL, ...) is called.
This time, do it the right way, and pacify GCC with a pragma.
This does make ld.so very slightly larger (0.3%) and doesn't seem to
actually improve performance; in fact, my limited testing suggested a
slight (0.1%) performance decrease (running fork/exec of a no-op program
in a loop), but I didn't do enough testing to establish statistical
significance.
However, Roland agrees that it makes sense to switch tile to using
this path, since it's the more standard way.
This patch fix the static build for strftime, which uses __wcschr.
Current powerpc32 implementation defines the __wcschr be an alias to
__wcschr_ppc32 and current implementation misses the correct alias for
static build.
It also changes the default wcschr.c logic so a IFUNC implementation
should just define WCSCHR and undefine the required alias/internal
definitions.

According to bug 6792, errno is not set to ERANGE/EDOM
by calling log1p/log1pf/log1pl with x = -1 or x < -1.
This patch adds a wrapper which sets errno in those cases
and returns the value of the existing __log1p function.
The log1p is now an alias to the wrapper function
instead of __log1p.
The files in sysdeps are reflecting these changes.
The ia64 implementation sets errno by itself,
thus the wrapper-file is empty.
The libm-test is adjusted for log1p-tests to check errno.

Bug 18247 is an off-by-one error in strtof's determination of a
decimal exponent such that any value with that decimal exponent is at
most half the least subnormal and so the appropriate underflowing
value for the rounding mode can be determined with no
multiple-precision computations. (Whether the value is in fact safe
despite the off-by-one depends on the floating-point format in
question. It's wrong for float and for m68k ldbl-96 but not for other
supported formats.) This patch corrects the computation of the
exponent in question to be safe in general, adding a comment
explaining the new computation.
Tested for x86_64.

The dbl-64 implementation of atan2 does computations that expect to
run in round-to-nearest mode, and in other modes the errors can
accumulate to more than the maximum accepted 9ulp. This patch makes
it use FE_TONEAREST internally, similar to other functions with such
issues. Tests that previously produced large errors are added for
atan2 and the closely related carg, clog and clog10 functions.
Tested for x86_64 and x86 and ulps updated accordingly.

On Alpha and IA-64, fexcept_t is unsigned long. But all the values
fit within an int, so the cast is ok for printing. All other hosts
use unsigned int or unsigned short already.
