/* This routine can be a real performance hog. According to some gprof data
which mtranle@paris.IntelliCorp.COM (Minh Tran-Le) sent, almost all the
time spend in solib_add (up to 20 minutes with 35 shared libraries) is
spent here, with 5/6 in lookup_minimal_symbol and 1/6 in read_memory.
/* In GDB 4.9 this routine was a real performance hog. According to
some gprof data which mtranle@paris.IntelliCorp.COM (Minh Tran-Le)
sent, almost all the time spend in solib_add (up to 20 minutes with
35 shared libraries) was spent here, with 5/6 in
lookup_minimal_symbol and 1/6 in read_memory.
Possible solutions:
* Hash the minimal symbols.
* Just record the name of the minimal symbol and lazily patch the
addresses.
* Tell everyone to switch to Solaris2.
(1) Move the call to special_symbol_handling out of the find_solib
loop in solib_add. This will call it once, rather than 35 times, when
you have 35 shared libraries. It's in the loop to pass the current
solib's objfile so the symbols are added to that objfile's minsym.
But since the symbols are in common (BSS), it doesn't really matter
which objfile's minsyms they are added to, I think.
(2) Indeed, it might be best to create an objfile just for common minsyms,
thus not needing any objfile argument to solib_add_common_symbols.
(3) Remove the call to lookup_minimal_symbol from
solib_add_common_symbols. If a symbol appears multiple times in the
minsyms, we probably cope, more or less. Note that if we had an
objfile for just minsyms, install_minimal_symbols would automatically
remove duplicates caused by running solib_add_common_symbols several
times.
*/
To fix this, we moved the call to special_symbol_handling out of the
loop in solib_add, so this only gets called once, rather than once
for every shared library, and also removed the call to lookup_minimal_symbol
in this routine. */
