| |
From: Andi Kleen <ak@linux.intel.com>
Some locales print floating point numbers with a comma instead of a dot. This causes problems with CSV mode because it causes extra false CSV fields. Force the numeric locale to be always C in CSV mode.
Before:
$ LC_ALL=pl_PL.utf8 perf stat -x, true 0,399472,,task-clock,399472,100,00 <---- extra bogus field ...
After: $ LC_ALL=pl_PL.utf8 ./obj-perf/perf stat -x, true 0.338422,,task-clock,338422,100.00
