#### notes.
|
||||
|
||||
1. on amd64, need to build V with -fno-omit-frame-pointer, else the
|
||||
w/ callgraph profiles are useless. (oprofile doesn't do CFI based
|
||||
stack unwinding, I guess). Add -fno-omit-frame-pointer to
|
||||
AM_CFLAGS_BASE in Makefile.flags.am, and rebuild from clean.
|
||||
|
||||
2. even at the best of times the callgraph profiles seem pretty
|
||||
flaky to me.
|
||||
|
||||
3. Even oprofile 0.9.4 (the latest) on amd64-linux doesn't work
|
||||
for callgraph profiling. There is however a patch that
|
||||
makes it work. See
|
||||
|
||||
http://sourceforge.net/tracker/index.php?func=detail&aid=1685267&group_id=16191&atid=116191
|
||||
|
||||
for details. Even then it sometimes fails at the "opcontrol
|
||||
--dump" phase, complaining that the daemon died (or something like
|
||||
that). But apart from that, it seems usable.
