If really your concern are psymtabs then use Tom's .gdb_index:
gdb/contrib/gdb-add-index.sh
With .gdb_index GDB still has startup performance problems during full
CU
expansions, that is struct symtab and struct symbol. That happens with
C++
inferiors which have very interlinked CUs and thus expanding one CU
means for
GDB expanding 100+ CUs due to the inter-type dependencies which cannot
be left
opaque in such cases. And as each C++ CU is usually very large...
