* Ensure that the mps builds with clang 10.Gareth Rees2021-01-101-1/+1
| | | | | | | | | | | | | | | | Clang 10 turns on -Wimplicit-int-float-conversion, and on 64-bit platforms this issues a warning that implicit conversions to double from Size and unsigned long "may lose precision". This commit adds casts to (double) for all such conversions. The loss of precision is either impossible in practice (because a double can represent all integers up to 2**53, which is about 9 petabytes, well beyond the addressing capabilities for current CPUs), or else acceptable, because we are accumulating an approximate quantity like "collection work" or "fill size" (that has to cope with loss of precision due in any case), or computing a threshold like the spare commit limit where it is acceptable for it to be somewhat approximate.

* Improve handling of telemetry events on the critical path:Gareth Rees2018-10-151-3/+3
| | | | | | | | | | | 1. Being on the critical path is a property of the code location where the event is emitted, not of the event type, so indicate this using EVENT_CRITICAL macros rather than a field in the event table. 2. Compile out events on the critical path in hot varieties. 3. Remove TraceFixWhite event (redundant with TraceFixSeg). 4. No need for special handling of PoolFree event -- this are already skipped in hot varieties by dispatching directly to the pool class via PoolFreeMacro. Copied from Perforce Change: 195261

| * Improve performance of mvff in hot builds by:Gareth Rees2018-07-041-12/+8
| | | | | | | | | | | | | | | | | | | | 1. Using macros to bypass PoolFree and Land* generic functions. 2. Compiling out assertions on functions on the critical paths for manual allocation and freeing. 3. Taking advantage of the fact that splay->updateNode does not change during a splay operation.

* Cherry-pick change 192595 from custom/cet/main, removing mps_addr_object. ↵Gareth Rees2016-10-191-19/+0
| | | | | | | | | this function failed to solve the problem of decoding the stack on 64-bit windows, because the stack may need to be decoded after an mps assertion failure, in which case the arena lock is held and mps_addr_object cannot be called. we eventually solved the problem in a different way (using mps_arena_postmortem) and mps_addr_object is no longer used.
