TLSF (https://github.com/jserv/tlsf-bsd) is a simple malloc/free which will be used in lieu of the current text space allocator. Its 2-clause BSD license is compatible with SBCL's.

-------
|
|
2014/02/08 - v3.0
|
|
* This version is based on improvements from 3DInteractive GmbH
|
|
* Interface changed to allow more than one memory pool
|
|
* Separated pool handling from control structure (adding, removing, debugging)
|
|
* Control structure and pools can still be constructed in the same memory block
|
|
* Memory blocks for control structure and pools are checked for alignment
|
|
* Added functions to retrieve control structure size, alignment size, min and
|
|
max block size, overhead of pool structure, and overhead of a single allocation
|
|
* Minimal Pool size is tlsf_block_size_min() + tlsf_pool_overhead()
|
|
* Pool must be empty when it is removed, in order to allow O(1) removal
|
|
|
|
2011/10/20 - v2.0
|
|
* 64-bit support
|
|
* More compiler intrinsics for ffs/fls
|
|
* ffs/fls verification during TLSF creation in debug builds
|
|
|
|
2008/04/04 - v1.9
|
|
* Add tlsf_heap_check, a heap integrity check
|
|
* Support a predefined tlsf_assert macro
|
|
* Fix realloc case where block should shrink; if adjacent block is
|
|
in use, execution would go down the slow path
|
|
|
|
2007/02/08 - v1.8
|
|
* Fix for unnecessary reallocation in tlsf_realloc
|
|
|
|
2007/02/03 - v1.7
|
|
* tlsf_heap_walk takes a callback
|
|
* tlsf_realloc now returns NULL on failure
|
|
* tlsf_memalign optimization for 4-byte alignment
|
|
* Usage of size_t where appropriate
|
|
|
|
2006/11/21 - v1.6
|
|
* ffs/fls broken out into tlsfbits.h
|
|
* tlsf_overhead queries per-pool overhead
|
|
|
|
2006/11/07 - v1.5
|
|
* Smart realloc implementation
|
|
* Smart memalign implementation
|
|
|
|
2006/10/11 - v1.4
|
|
* Add some ffs/fls implementations
|
|
* Minor code footprint reduction
|
|
|
|
2006/09/14 - v1.3
|
|
* Profiling indicates heavy use of blocks of
|
|
size 1-128, so implement small block handling
|
|
* Reduce pool overhead by about 1kb
|
|
* Reduce minimum block size from 32 to 12 bytes
|
|
* Realloc bug fix
|
|
|
|
2006/09/09 - v1.2
|
|
* Add tlsf_block_size
|
|
* Static assertion mechanism for invariants
|
|
* Minor bugfixes
|
|
|
|
2006/09/01 - v1.1
|
|
* Add tlsf_realloc
|
|
* Add tlsf_walk_heap
|
|
|
|
2006/08/25 - v1.0
|
|
* First release
