From: Jiri Olsa Date: Fri, 15 Jun 2012 06:31:38 +0000 (+0800) Subject: perf/tool: Use data struct for arg passing in event parse function X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=46010ab2607aed9484816a8f1679c2ec3c8e7dcf;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git perf/tool: Use data struct for arg passing in event parse function Moving all the bison arguments into the structure. In upcomming patches we are going to: - add more arguments - reuse the grammer for term parsing so it's more clear to pack/separate related arguments.
