[RFA] update ggc_min_heapsize_heuristic()

2017-04-09 Thread Markus Trippelsdorf
The minimum size heuristic for the garbage collector's heap, before it starts collecting, was last updated over ten years ago. It currently has a hard upper limit of 128MB. This is too low for current machines where 8GB of RAM is normal. So, it seems to me, a new upper bound of 1GB would be appropr

Renaming moutline-msabi-xlogues to mcall-ms2sysv-xlogues
