Subject: Remove parameter from select_source_symtab
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=62c5d5ec88c5748491e27e1fbd3953f4c872752d;p=binutils-gdb.git

Remove parameter from select_source_symtab

I noticed that select_source_symtab is only ever called with nullptr
as an argument, so this patch removes the parameter and associated
logic.
