[PATCH] D101427: Linux support for mimalloc as a custom allocator

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Perhaps we don't need additional CMake code for using an alternative malloc on Linux.
For example, to use mimalloc it is simply `-DCMAKE_EXE_LINKER_FLAGS=-Wl,--push-state,--whole-archive,path/to/libmimalloc.a,--pop-state`

When linking a default build of chrome (no debug) and a Release build of clang, using libmimalloc.a is 1.12x as fast. LD_PRELOAD=path/to/libmimalloc.so is 1.11x as fast.
