kuszmaul / Supermalloc

To build for release

cd release make make check

You get two libraries in release/lib libsupermalloc.so requires transactional memory (haswell) libsupermalloc_pthread.so uses pthread locks I plan to add a runtime check and have only one library and an enviroment variable in the future.

You should also build and check with the internal testing code enabled. It's a different library partly because of link-time optimization. Also, if you want things easier to compile. There are two differences, we enable the TESTING flag (which includes a bunch of code that can be compiled) and we set -O0.

cd debug make check

To run code coverage cd coverage make check

At top level you can do make clean make make check
