ee72bf1cfd Tcache: Add tcache gc delay option. 
This can reduce flushing frequency for small size classes.

27f29e424b LQ_QUANTUM should be 4 on mips64 hardware. 
This matches the ABI stack alignment requirements.

eda9c2858f Edata: zero stack edatas before initializing. 
This avoids some UB. No compilers take advantage of it for now, but no sense in
tempting fate.

fef9abdcc0 Cleanup tcache allocation logic 
The logic in tcache allocation no longer involves profiling or
filling.

e6cb6919c0 Consolidate prof inline function headers 
The prof inline functions are no longer involved in a circular
dependency, so consolidate the two headers into one.

David Goldblatt
79dd0c04ed SC: Simplify SC_NPSIZES computation. 
Rather than taking all the sizes and subtracting out those that don't fit, we
instead just add up all the ones that do.

4f8efba824 TSD: Make rtree_ctx a slow-path field. 
Performance-sensitive users will use sized deallocation facilities, so that
actually touching the rtree_ctx is unnecessary.  We make it the last element of
the slow data, so that it is for practical purposes almost-fast.

40e7aed59e TSD: Move in some of the tcache fields. 
We had put these in the tcache for cache optimization reasons.  After the
previous diff, these no longer apply.

79ae7f9211 Rtree: Remove the per-field accessors. 
We instead split things into "edata" and "metadata".

bb6a418523 Emap: Drop szind/slab splitting parameters. 
After the previous diff, these are constants.

93b99dd140 Extent: Stop passing an edata_cache everywhere. 
We already pass the pa_shard_t around everywhere; we can just use that.

11c47cb133 Extent: Take "bool zero" over "bool *zero". 2020-04-10 13:12:47 -07:00
David Goldblatt
1a1124462e PA: Take zero as a bool rather than as a bool *. 
Now that we've moved junking to a higher level of the allocation stack, we don't
care about this performance optimization (which only occurred in debug modes).

294b276fc7 PA: Parameterize emap. Move emap_global to arena. 
This lets us test the PA module without interfering with the global emap used by
the real allocator (the one not under test).

f730577277 Eset: Parameterize last globals accesses. 
I.e. opt_retain and maps_coalesce.
 2020-04-10 13:12:47 -07:00
David Goldblatt
7bb6e2dc0d Eset: take opt_lg_max_active_fit as a parameter. 
This breaks its dependence on the global.

12eb888e54 Edata: Add a ranged bit. 
We steal the dumpable bit, which we ended up not needing.
