time/mem report compiling compiler.i
This is the time and detailed memory report for compiling compiler.i with
today's gcc and optimization level -O3 -fschedule-insns. Again, the detailed
configuration information and command line are contained at the beginning of
the file.
Except for taking > 20GB of RAM, this doesn't look too bad, either. The passes
taking the most time are:
parser : 222.18 (21%) usr 2.95 (11%) sys 225.37 (21%) wall
103148 kB (11%) ggc
tree CFG cleanup : 63.67 ( 6%) usr 0.00 ( 0%) sys 63.60 ( 6%) wall
2467 kB ( 0%) ggc
scheduling : 394.04 (37%) usr 0.00 ( 0%) sys 394.04 (36%) wall
5824 kB ( 1%) ggc
TOTAL :1056.69 26.47 1083.41
