49 49 * libld_malloc() and dz_map() are used for both performance and for ease of
50 50 * programming:
51 51 *
52 52 * Performance:
53 53 * The link-edit is a short lived process which doesn't really free much
54 54 * of the dynamic memory that it requests. Because of this, it is more
55 55 * important to optimize for quick memory allocations than the
56 56 * re-usability of the memory.
57 57 *
58 58 * By also mmaping blocks of pages in from /dev/zero we don't need to
59 59 * waste the overhead of zeroing out these pages for calloc() requests.
60 60 *
61 61 * Memory Management:
62 62 * By doing all libld memory management through the ld_malloc routine
63 63 * it's much easier to free up all memory at the end by simply unmaping
64 64 * all of the blocks that were mapped in through dz_map(). This is much
65 65 * simpler then trying to track all of the libld structures that were
66 66 * dynamically allocate and are actually pointers into the ELF files.
67 67 *
68 68 * It's important that we can free up all of our dynamic memory because
69 69 * libld is used by ld.so.1 when it performs dlopen()'s of relocatable
70 70 * objects.
71 71 *
72 72 * Format:
73 73 * The memory blocks for each allocation store the size of the allocation
74 74 * in the first 8 bytes of the block. The pointer that is returned by
75 75 * libld_malloc() is actually the address of (block + 8):
76 76 *
77 77 * (addr - 8) block_size
78 78 * (addr) <allocated block>
79 79 *
80 80 * The size is retained in order to implement realloc(), and to perform
81 81 * the required memcpy(). 8 bytes are uses, as the memory area returned
82 82 * by libld_malloc() must be 8 byte-aligned. Even in a 32-bit environment,
83 83 * u_longlog_t pointers are employed.
84 84 *
85 85 * Map anonymous memory via MAP_ANON (added in Solaris 8).
