New Revision: 16461
Log:
New command line option "--terse" for vg_perf.
Fixes BZ#382407.
Produces the following terse output:
-- bigcode1 --
vanilla : no: ----- me: ----- ca: ----- he: ----- ca: ----- dr: ----- ma: -----
ra3-005 : no: 0.0% me: -4.7% ca: 0.2% he: -1.1% ca: -1.5% dr: -0.6% ma: 0.0%
ra3-005-J : no: 0.0% me: 0.4% ca: 0.3% he: -0.5% ca: -0.9% dr: 0.0% ma: 0.6%
ra3-006 : no: 0.0% me: 0.4% ca: 0.2% he: -0.0% ca: -1.2% dr: 0.0% ma: 0.0%
ra3-007 : no: 0.0% me: 0.7% ca: 0.5% he: -0.5% ca: -0.6% dr: 0.0% ma: 1.2%
instead the full output (when the option is not used):
-- bigcode1 --
bigcode1 vanilla:0.09s no: 1.6s (18.0x, -----) me: 3.1s (35.0x, -----) ca:12.7s (140.8x, -----) he: 2.0s (22.8x, -----) ca: 3.7s (41.2x, -----) dr: 2.0s (22.2x, -----) ma: 1.9s (20.7x, -----)
bigcode1 ra3-005:0.09s no: 1.6s (17.8x, 1.2%) me: 3.0s (33.3x, 4.8%) ca:12.7s (140.7x, 0.1%) he: 2.0s (22.2x, 2.4%) ca: 3.6s (40.2x, 2.4%) dr: 1.9s (21.7x, 2.5%) ma: 1.9s (20.7x, 0.0%)
