Description Ivo Raisr 2017-07-16 20:00:44 UTC

Script vg_perf produces too much output when running with several Valgrind tools
and comparing performance for several Valgrind directories.

Consider for example:
-- Running  tests in perf ----------------------------------------------
bigcode1 valgrind-reg_alloc3:0.09s  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 valgrind-linux: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%)

and you are lost.


New command line option "--terse" produces, well, terse output:
-- Running  tests in vanilla/perf --------------------------------------
-- 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%
