2012-08-22rename V variable to lib-versionMike Frysinger2-2/+7
Due to the rise of kbuild type build systems (as the Linux kernel is a popularly emulated environment), the V variable has become common as a knob for controlling verbosity. Unfortunately, if you run `make V=1` with glibc during install, it fails with weird errors due to the glibc build already using this variable for versioning information. Granted, overriding this variable in the glibc context makes no sense so people shouldn't be doing it, but when paired with build frameworks that like to use one set of options for all packages, glibc starts to stick out as an oddball (in that it fails). Considering it's easy enough to rename (it's used in just one place), let's do so. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-08-22Add versions of wcscpy, wcschr, wcsrchr for power6/power7.Will Schmidt8-2/+298
Initially based on the versions found in wcsmbs/* ; these files have been changed by hand unrolling, and adding some additional variables to allow some read-ahead to occur, which then relieves some of the wait-for-increment/wait-for-load/wait-for-compare-results pressure that was slowing down every iteration through the while-loop. For 64-bit Power7, These changes give an approx 20% throughput boost for the wcschr and wcsrchr functions; and approx 40% boost for the wcscpy function. 32-bit improvements appear to be slightly better with ~ %30 and ~ %45 respectively. Results for Power6 closely match those for power7.

2012-08-21[Powerpc] Tune/optimize powerpc{32,64}/power7/memchr.S.Will Schmidt3-44/+125
Assorted tweaking, twisting and tuning to squeeze a few additional cycles out of the memchr code. Changes include bypassing the shift pairs (sld,srd) when they are not required, and unrolling the small_loop that handles short and trailing strings. Per scrollpipe data measuring aligned strings for 64-bit, these changes save between five and eight cycles (9-13% overall) for short strings (<32), Longer aligned strings see slight improvement of 1-3% due to bypassing the shifts and the instruction rearranging.

2012-08-18add attribute_hidden to __have_{sock_cloexec,pipe2,dup3Mike Frysinger3-4/+11
These internal knobs are not exposed as part of the public ABI, so mark them hidden to avoid generating relocations against them. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-08-18split assume pipe2/dup3/sock_cloexec knobsMike Frysinger3-6/+21
We can't assume sock_cloexec and pipe2 are bound together as the former defines are found in glibc only while the latter are a combo of kernel headers and glibc. So if we do a runtime detection of SOCK_CLOEXEC, but pipe2() is a stub inside of glibc, we hit a problem. For example: main() { getgrnam("portage"); if (!popen("ls", "r")) perror("popen()"); } getgrnam() will detect that the kernel supports SOCK_CLOEXEC and then set both __have_sock_cloexec and __have_pipe2 to true. But if glibc was built against older kernel headers where __NR_pipe2 does not exist, glibc will have a ENOSYS stub for it. So popen() will always fail as glibc assumes pipe2() works. While this isn't too much of an issue for some arches as they added the functionality to the kernel at the same time, not all arches are that lucky. Since the code already has dedicated names for each feature, delete the defines wiring these three features together and make each one a proper dedicated knob. We've been carrying this in Gentoo since glibc-2.9. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

When unmapping the first object in a namespace, the runtime linker did not update the externally visible pointer. This resulted in debuggers seeing pointers to memory that had been freed.

2012-08-16Fifth argument of la_pltenter() is not constant.Carlos O'Donell9-8/+32
The original runtime linker auditing interface described by Solaris allows the 5th argument of la_pltenter() to be modified. This patch cleans up the ldsodefs.h definitions such that the 5th argument is not constant. At one point the 5th argument *was* constant but this was changed with commit 2413fdba7a02ba8916f75d17199a6e9133a8f7b0. This patch updates alpha, ia64, mips, sh and sparc with similar changes.
