Jason Evans	f193fd80cf	Refactor runs_avail. Use pszind_t size classes rather than szind_t size classes, and always reserve space for NPSIZES elements. This removes unused heaps that are not multiples of the page size, and adds (currently) unused heaps for all huge size classes, with the immediate benefit that the size of arena_t allocations is constant (no longer dependent on chunk size).	2016-10-04 19:48:50 -07:00

Refactor runs_avail.

Use pszind_t size classes rather than szind_t size classes, and always
reserve space for NPSIZES elements.  This removes unused heaps that are
not multiples of the page size, and adds (currently) unused heaps for
all huge size classes, with the immediate benefit that the size of
arena_t allocations is constant (no longer dependent on chunk size).

Use table lookup for run_quantize_{floor,ceil}().

Reduce run quantization overhead by generating lookup tables during
bootstrapping, and using the tables for all subsequent run quantization.

Also rename run_quantize_*() to improve clarity.  These tests
demonstrate that run_quantize_ceil() is flawed.
