- Update to 2.9.1:
* usage of unsupportable linux_syscall_support.h has been
removed from few places.
* Incorrect assertion failure was fixed that crashed tcmalloc
if assertions were on and sized delete was used
* there is now better backtracing support for aarch64 and riscv
x86-64 with frame pointers now also defaults to this new
"generic" frame pointer backtracer.
- Use golang version of pprof
- Split doc into subpackage
OBS-URL: https://build.opensuse.org/request/show/879979
OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/gperftools?expand=0&rev=56
- Update to 2.8.1:
* previous release contained change to release memory without page
heap lock, but this change had at least one bug that caused to
crashes and corruption when running under aggressive decommit mode
(this is not default). While we check for other bugs, this feature
was reverted. See github issue #1204 and issue #1227.
* stack traces depth captured by gperftools is now up to 254 levels
deep
* updated detection of program counter
* ProfilerGetStackTrace is now officially supported API for
libprofiler
* for compiling linux syscall support on i386 and recent GCCs
* test failures caused by new gcc 10 optimizations were fixed. Same
change also fixed tests on clang.
- Drop ppc64-fix-367fd5731a8c68225cb870aa656ea0ce677fe040.patch
- Drop gcc-dont-clobber-rsp.patch

- Add ppc64-fix-367fd5731a8c68225cb870aa656ea0ce677fe040.patch
in order to address power targets.
- Update to version 2.7:
* bug in span stats printing introduced by new scalable page heap
change was fixed.
* Christoph Müllner has contributed couple warnings fixes and
initial support for aarch64_ilp32 architecture.
* Ben Dang contributed documentation fix for heap checker.
* Fabrice Fontaine contributed fixed for linking benchmarks
with --disable-static.
* Holy Wu has added sized deallocation unit tests.
* Holy Wu has enabled support of sized deallocation (c++14)
on recent MSVC.
* Holy Wu has fixed MSVC build in WIN32_OVERRIDE_ALLOCATORS
mode. This closed issue #716.
* Holy Wu has contributed cleanup of config.h used on windows.
* Mao Huang has contributed couple simple tcmalloc changes from
chromium code base. Making our tcmalloc forks a tiny bit closer.
* issue #946 that caused compilation failures on some Linux
clang installations has been fixed. Much thanks to github
user htuch for helping to diagnose issue and proposing a fix.
* Tulio Magno Quites Machado Filho has contributed build-time
fix for PPC (for problem introduced in one of commits
since RC).
- Add gcc-dont-clobber-rsp.patch (bsc#1121265).

- 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.

+ * ( issue 641 ) pprof now has an option --show_addresses (thanks to

- 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.

- gperftools 2.1, released 30 July 2013.
* fixes for building on newer platforms. Notably, there's now initial
support for x32 ABI (--enable-minimal only at this time))
* Some fixes for debug allocation on POWER/Linux
* new getNumericProperty stats for cache sizes
* added HEAP_PROFILER_TIME_INTERVAL variable (see documentation)
* added environment variable to control heap size (TCMALLOC_HEAP_LIMIT_MB)
* added environment variable to disable release of memory back to OS
(TCMALLOC_DISABLE_MEMORY_RELEASE)
* cpu profiler can now be switched on and off by sending it a signal
(specified in CPUPROFILESIGNAL)
* (issue 491) fixed race-ful spinlock wake-ups
* (issue 496) added some support for fork-ing of process that is using
tcmalloc
* (issue 368) improved memory fragmentation when large chunks of
memory are allocated/freed
