Here are data comparing tr...@148582 (last merge point to VTA branch) with
v...@149180 (current VTA branch head), using maxmem2.sh and maxmem-pipe2.py.
Both compilers were built with --enable-checking=release, all numbers are
on x86_64-linux from cc1 resp. cc1plus (*.i resp. *.ii) with -g -quiet and
the options listed in the header line.
The only major compile time memory consumption problem is in VARIOUS/,
particularly pr28071.i where var-tracking goes through roof, I hope Alex
will look into it, worst case we could just silently turn off
flag_var_tracking_assignments in var-tracking.c for functions which have
too many basic blocks and too many VALUEs to track.
I'm now running compilations with -ftime-report, once that finishes will
post statistics for compile time as well, then size of IL.
