I've rebuilt with -pg in the following directories:
. libiberty
. bfd
. opcodes
. libctf
. gdbsupport
. gdb
The profile produced by gprof is attached. The time information looks
very inaccurate, almost bogus, to me (since GDB ran for more than 2
minutes, I expected to see gdb_main show 130 as the value of
cumulative seconds, but the profile shows only 2.21?). But
nevertheless I hope the data will be useful.
Let me know if I can provide more information.
