Safe Tcmalloc Compilation Support

We defaultly install to /usr/local/lib, if we need to remove them, just run xargs rm < install_manifest.txt
Make sure you have cmake >= 3.21.4
Make sure you have /usr/bin/c++ > 9.0
Make sure you have installed absl correctly by absl_install.sh
To build tcmalloc correctly, run the following cmds:

# build tcmalloc
cmake .
make -j`nproc`
make install
# set env
echo "PATH=$HOME/usr/local/bin:$PATH:$HOME/bin" >> ~/.bashrc
echo "LD_LIBRARY_PATH=/usr/local/lib64:/usr/local/lib:$HOME/lib:/$LD_LIBRARY_PATH" >> ~/.bashrc
echo "export PATH" >> ~/.bashrc
echo "export LD_LIBRARY_PATH" >> ~/.bashrc
source ~/.bashrc
# run the test in tcmalloc/test/test.cc by tcmalloc/test/compile.sh
cd test
./compile
ls -lh ./test.out
ldd -r ./test.out

Safe Tcmalloc Gprof Support

enable GPROF in menuconfig
re-build the safe_tcmalloc
exec tcmalloc/build_static.sh to generate .a file
compile your file by v++ and exec it, after normally exit, a gmon.out will be generated.
then exec: gprof yourfile gmon.out > analysis.txt

TCMalloc

This repository contains the TCMalloc C++ code.

TCMalloc is Google's customized implementation of C's malloc() and C++'s operator new used for memory allocation within our C and C++ code. TCMalloc is a fast, multi-threaded malloc implementation.

Building TCMalloc

Bazel is the official build system for TCMalloc.

The TCMalloc Platforms Guide contains information on platform support for TCMalloc.

Documentation

All users of TCMalloc should consult the following documentation resources:

The TCMalloc Quickstart covers downloading, installing, building, and testing TCMalloc, including incorporating within your codebase.
The TCMalloc Overview covers the basic architecture of TCMalloc, and how that may affect configuration choices.
The TCMalloc Reference covers the C and C++ TCMalloc API endpoints.

More advanced usages of TCMalloc may find the following documentation useful:

The TCMalloc Tuning Guide covers the configuration choices in more depth, and also illustrates other ways to customize TCMalloc. This also covers important operating system-level properties for improving TCMalloc performance.
The TCMalloc Design Doc covers how TCMalloc works underneath the hood, and why certain design choices were made. Most developers will not need this level of implementation detail.
The TCMalloc Compatibility Guide which documents our expectations for how our APIs are used.
