[Valgrind-users] How does callgrind detect loops?

[Yang L. <yan...@em...>]

Hi, guys!

I'm profiling postgreSQL with callgrind. Basically, there's a call chain in
the following order.

ExecProcNode->ExecAgg->ExecProcNode->ExecSeqScan

ExecProcNode is called recursively through intermediate functions. And the
output file marked the second call to ExecProcNode as a call to
ExecProcNode'2.

I read the manual, mailing list archive and callgrind's output format. But
that doesn't help me.
Cheers,
