12 years agorename V variable to lib-version
Mike Frysinger [Wed, 22 Aug 2012 04:21:31 +0000 (00:21 -0400)]
rename V variable to lib-version

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.

Will Schmidt [Wed, 22 Aug 2012 16:04:42 +0000 (11:04 -0500)]
Add versions of wcscpy, wcschr, wcsrchr for power6/power7.

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.

wcscpy function.  32-bit improvements appear to be slightly better
with ~ %30 and ~ %45 respectively.  Results for Power6 closely match

Mike Frysinger [Sat, 18 Aug 2012 02:03:56 +0000 (22:03 -0400)]
split assume pipe2/dup3/sock_cloexec knobs

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.
