Subject: [gdb/symtab] Add lazy_expand_symtab_p, default to false
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=744ed1ee391fa604fe9eb854f5ca25120061c832;p=thirdparty%2Fbinutils-gdb.git

[gdb/symtab] Add lazy_expand_symtab_p, default to false

Add variable to enable lazy symbol table expansion.

Set to false for now, to enable gradual introduction of implementation.

Make user-settable using "maint set/show lazy-expand-symtab on/off".
