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
v2 changes:
- added -L as short option for call-graph for record/top commands
- updated documentation
- based on latest acme's perf/urgent
thanks,
jirka
