Richard Kistruck 1ff022cae1 mps br/vmem: simple-chunk-return: ... zcoll.c: How to get rid of all the objects, so full collect really collects all automatic objects: - Rootdrop() helps, but we can still retain a 1.2MB object; - stackwipe() does not help much -- these unwanted ambig refs are being left on the stack by MPS code that runs between mps_arena_collect and the flip! - therefore StackScan(0/1) to destroy stack+reg root before full collect: it's the only way to be sure. Reproducibility: - give Make() a random? switch, acted on by df() = diversity function, to allow bypass of rnd(); - ZRndStateSet, to set the seed for rnd() Output: - print_M: switchable Mebibytes or Megabytes (more useful, to be honest); - get(): don't report message times, it messes up diffs. testlib.c/h: Reproducibility: - fix rnd_state so a rnd_state getter is possible; - testlib.h += rnd_state_t, rnd_state(), rnd_state_set(), rnd_state_set_v2() trace.c: traceFindGrey diag: no newline please Copied from Perforce Change: 170093 ServerID: perforce.ravenbrook.com		2010-03-22 23:00:42 +00:00
