This - list is useful if we need to find a suitable memory area when the allocator - is called. - - When a block is freed, the new free block is connected to its adjacent free - blocks if possible. - - [ free block ][ used block ][ free block ] - and "used block" is freed, the three blocks are connected together: - [ one big free block ] -*/ - -/* --------------------------------------------------------------------- */ -/* System (OS) functions */ -/* --------------------------------------------------------------------- */ - -/* 64 KByte. */ -#define CHUNK_SIZE (sljit_uw)0x10000 - -struct chunk_header { - void *executable;
