# DISCLAIMER! This is a quick hack I did to test things. Don't use!

An ultra simple single-threaded linear allocator.

Useful to make the output of applications running under Cachegrind/Callgrind

more stable (since it doesn't try to do the clever optimizations that the

system allocator does).

## Usage

Linux:

```sh

cargo build

LD_PRELOAD=./target/debug/liblinear_malloc.so your-binary

```

macOS:

```sh

cargo build

DYLD_INSERT_LIBRARIES=./target/debug/liblinear_malloc.dylib DYLD_FORCE_FLAT_NAMESPACE=1 your-binary

```

## Acknowledgements

Got some useful info about allocation strategies from [@mtrebi's `memory-allocators`](https://github.com/mtrebi/memory-allocators), and [@ezrosent's "Allocators in Rust"](https://github.com/ezrosent/allocators-rs) was a good source to help set up the basic framework.
