Define Documentation

#define tm_DEFAULT_ALLOC_COLOR   tm_ECRU

Default allocated nodes to "not marked".

Rational: some are allocated but thrown away early.

Definition at line 237 of file tm.c.

#define tm_SWEEP_ALLOC_COLOR   tm_GREY

Default allocated node color during sweep.

Rational: tm_ECRU is considered garabage during tm_SWEEP.

Assume that new nodes are actually in-use and may contain pointers to prevent accidental sweeping.

Definition at line 248 of file tm.c.

Enumeration Type Documentation

enum tm_color

The color of a node.

Values greater than tm_BLACK are used as indicies into accounting arrays.

Enumerator:

tm_WHITE	Node colors. Free, in free list.
tm_ECRU	Allocated.
tm_GREY	Marked in use, scheduled for interior scanning.
tm_BLACK	Marked in use, scanned.
tm_TOTAL	Accounting. Total nodes of any color.
tm__LAST
tm_B	Type-level Stats. Total blocks in use.
tm_CAPACITY
tm_NU	Total nodes in use.
tm_b	Total bytes in use.
tm_b_NU	Avg bytes/node.
tm__LAST2
tm_B_OS	Block-level Stats. Blocks currently allocated from OS.
tm_b_OS	Bytes currently allocated from OS.
tm_B_OS_M	Peak blocks allocated from OS.
tm_b_OS_M	Peak bytes allocated from OS.
tm__LAST3
tm_FREE_BLOCK	Aliases for internal structure coloring. Color of a free tm_block.
tm_LIVE_BLOCK	Color of a live, in-use tm_block.
tm_FREE_TYPE	Color of a free tm_type.
tm_LIVE_TYPE	Color of a live, in-use tm_type.
