hi, changing the '-g/-G' options for record/top commands to take NO argument and enable unwind method based on .perfconfig setup (using FP by default).
The current -g option parsing moves into the '--call-graph' option.
Examples: $ cat ~/.perfconfig: [top] call-graph = fp
[record] call-graph = dwarf,8192
$ perf record -g ls - enables dwarf unwind with user stack size dump 8192 bytes
$ perf top -G - enables frame pointer unwind
$ perf record --call-graph=fp ls - enables frame pointer unwind
$ perf top --call-graph=dwarf,4096 ls - enables dwarf unwind with user stack size dump 4096 bytes
thanks, jirka
