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.

12 years agoAdd versions of wcscpy, wcschr, wcsrchr for power6/power7.
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.

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.
