Subject: Add an option to specify a list of methods for LIR dumping.
X-Git-Tag: android-x86-7.1-r1~889^2~4349^2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=42d65c52bbf4a354605389a759190e793787f692;p=android-x86%2Fart.git

Add an option to specify a list of methods for LIR dumping.

An example would be:
--runtime-arg -verbose-methods:Array.checkRange32,Array.checkRange64
or
"-verbose-methods:void Array.checkRange32,void Array.checkRange64"
