| Dart uses tcmalloc in the standalone VM on Linux. |
| |
| To roll tcmalloc forward: |
| . Clone the gperftools git repo at the revision you want in a directory off |
| to the side. |
| |
| . Run a configure command similar to the one in the configure_command file in |
| this directory. It is up to you to determine if different flags are required |
| for the newer gperftools. |
| |
| . From that repo, copy src/config.h and src/gperftools/tcmalloc.h, and any other |
| generated header files to the include/ directory in this directory. |
| |
| . Also copy the COPYING file and any other relevant licensing information. |
| |
| . Make sure that include/config.h defines HAVE_UCONTEXT_H on Linux, |
| |
| . Update tcmalloc_sources.gypi, and tcmalloc.gyp if necessary. This may require |
| inspecting gperftools/Makefile.am to see any additional source files and |
| preprocessor defines (-D flags). |
| |
| . Update the DEPS file with the new git hash. |
| |
| . Build and run tests for Debug, Release, and Product builds for ia32, x64, |
| and arm for Linux and any other OSs that are supported. |
