2012-09-25Shrink heap on linux when overcommit_memory == 2Siddhesh Poyarekar
Using madvise with MADV_DONTNEED to release memory back to the kernel is not sufficient to change the commit charge accounted against the process on Linux. It is OK however, when overcommit is enabled or is heuristic. However, when overcommit is restricted to a percentage of memory setting the contents of /proc/sys/vm/overcommit_memory as 2, it makes a difference since memory requests will fail. Hence, we do what we do with secure exec binaries, which is to call mmap on the region to be dropped with MAP_FIXED. This internally unmaps the pages in question and reduces the amount of memory accounted against the process.

2012-08-29Don't make ttyname* fail if proc filesystem is not availableSiddhesh Poyarekar
The ttyname and ttyname_r functions on Linux now fall back to searching for the tty file descriptor in /dev/pts or /dev if /proc is not available. This allows creation of chroots without the procfs mounted on /proc. Fixes BZ #14516.

2012-08-22Add versions of wcscpy, wcschr, wcsrchr for power6/power7.Will Schmidt
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 Schmidt
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.

2012-08-16Fifth argument of la_pltenter() is not constant.Carlos O'Donell
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.
