- gperftools 2.4, available 10 Jan 2015.
Skipped version 2.3, release 7 Dec 2014.
Changes for version 2.4
* enabled aggressive decommit option by default. It was found to
significantly improve memory fragmentation with negligible impact
on performance. (Thanks to investigation work performed by Adhemerval
Zanella)
* added ./configure flags for tcmalloc pagesize and tcmalloc allocation
alignment. Larger page sizes have been reported to improve performance
occasionally. (Patch by Raphael Moreira Zinsly)
* sped-up hot-path of malloc/free. By about 5% on static library and
about 10% on shared library. Mainly due to more efficient checking
of malloc hooks.
* improved accuracy of stacktrace capturing in cpu profiler (due to
issue found by Arun Sharma). As part of that issue pprof's handling
of cpu profiles was also improved.
- Removed missing_includes.patch; incorporated upstream.

+- gperftools 2.4, available 10 Jan 2015.
+ Skipped version 2.3, release 7 Dec 2014. 2.3 changes included:
+ * ( issue 631 ) fixed debugallocation miscompilation on mmap-less
+ platforms (courtesy of user iamxujian)
+ * ( issue 630 ) reference to wrong PROFILE (vs. correct CPUPROFILE)
+ environment variable was fixed (courtesy of WenSheng He)
+ * pprof now has option to display stack traces in output for heap
+ checker (courtesy of Michael Pasieka)
+ * ( issue 636 ) pprof web command now works on mingw
+ * ( issue 635 ) pprof now handles library paths that contain spaces
+ (courtesy of user mich...@sebesbefut.com)
+ * ( issue 637 ) pprof now has an option to not strip template
+ arguments (patch by jiakai)
+ * ( issue 644 ) possible out-of-bounds access in GetenvBeforeMain
+ was fixed (thanks to user abyss.7)
+ * ( issue 641 ) pprof now has an option --show_addresses (thanks to
+ user yurivict). New option prints instruction address in addition
+ to function name in stack traces
+ * ( issue 646 ) pprof now works around some issues of addr2line
+ reportedly when DWARF v4 format is used (patch by Adam McNeeney)
+ * ( issue 645 ) heap profiler exit message now includes remaining
+ memory allocated info (patch by user yurivict)
+ * pprof code that finds location of /proc/pid/maps in cpu profile
+ files is now fixed (patch by Ricardo M. Correia)
+ * ( issue 654 ) pprof now handles "split text segments" feature of
+ Chromium for Android (patch by simonb)
+ * ( issue 655 ) potential deadlock on windows caused by early call
+ to getenv in malloc initialization code was fixed (bug reported
+ and fix proposed by user zndmitry)
+ * incorrect detection of arm 6zk instruction set support
+ (-mcpu=arm1176jzf-s) was fixed. (Reported by pedronavf on old issue-493)
+ * new cpu profiling mode on Linux is now implemented. It sets up separate
+ profiling timers for separate threads. Which improves accuracy of
+ profiling on Linux a lot. It is off by default. And is enabled if both
+ librt.f is loaded and CPUPROFILE_PER_THREAD_TIMERS environment
+ variable is set. But note that all threads need to be registered
+ via ProfilerRegisterThread.

- PowerPC: stacktrace function refactor and fixes
-
- This patch fixes the stacktrace creating when the function is
- interrupted by a signal. For Linux, the vDSO signal trampoline symbol is
- compared against LR from stack backchain and handled different in that
- case (since the signal trampoline layout a different stack frame).
-
- Because of this extensive change the PowerPC stacktrace code has now
- been refactored to split in Linux and Darwin specific codes.
