Added two new configure flags, --with-tcmalloc-pagesize and
--with-tcmalloc-alignment, in order to set the tcmalloc internal page
size and tcmalloc allocation alignment without the need of a compiler
directive and to make the choice of the page size independent of the
allocation alignment.

So that it's easier to contribute and review contributions.
People wishing to build gperftools from svn checkout should run
autogen.sh first which will create those files and then ./configure &&
make as usual
INSTALL file has updated instructions too.

That was accidently overwritten by autotools files update in r196

tcmalloc contained a bug where some internal locks were left in a undefined state
between fork, leaving the child process in a deadlock state. This patch fixes the
issue by introducing stricter locking between the parent nd child while forking.

In revisions 151 and 150 an attempt was made to enable frame pointers by default for i386. However, in the process of doing so a number of files were inadvertently touched as a result of running autogen.sh. As a result, I have needed to roll back these revisions so that I can reattempt the change.

* google-perftools: version 0.92 release
* PERFORMANCE: use a packed cache to speed up tcmalloc
* PORTING: preliminary windows support! (see README.windows)
* PORTING: better support for solaris, OS X, FreeBSD (see INSTALL)
* Envvar support for running the heap-checker under gdb
* Add weak declarations to maybe_threads to fix no-pthreads compile bugs
* Some 64bit fixes, especially with pprof
* Better heap-checker support for some low-level allocations
* Fix bug where heap-profiles would sometimes get truncated
* New documentation about how to handle common heap leak situations
* Use computed includes for hash_map/set: easier config
* Added all used .m4 templates to the distribution

* google-perftools: version 0.90 release
* (As the version-number jump hints, this is a major new release:
almost every piece of functionality was rewritten. I can't do
justice to all the changes, but will concentrate on highlights.)
*** USER-VISIBLE CHANGES:
* Ability to "release" unused memory added to tcmalloc
* Exposed more tweaking knobs via environment variables (see docs)
* pprof tries harder to map addresses to functions
* tcmalloc_minimal compiles and runs on FreeBSD 6.0 and Solaris 10
*** INTERNAL CHANGES:
* Much better 64-bit support
* Better multiple-processor support (e.g. multicore contention tweaks)
* Support for recent kernel ABI changes (e.g. new arg to mremap)
* Addition of spinlocks to tcmalloc to reduce contention cost
* Speed up tcmalloc by using __thread on systems that support TLS
* Total redesign of heap-checker to improve liveness checking
* More portable stack-frame analysis -- no more hard-coded constants!
* Disentangled heap-profiler code and heap-checker code
* Several new unittests to test, e.g., thread-contention costs
* Lots of small (but important!) bug fixes: e.g., fixing GetPC on amd64
*** KNOWN PROBLEMS:
* CPU-profiling may crash on x86_64 (64-bit) systems. See the README
* Profiling/heap-checking may deadlock on x86_64 systems. See README

* google-perftools: initial release:
The google-perftools package contains some utilities to improve
and analyze the performance of C++ programs. This includes an
optimized thread-caching malloc() and cpu and heap profiling
utilities.
