From: Tom Tromey Date: Sat, 20 Mar 2021 23:23:40 +0000 (-0600) Subject: Introduce objfile::require_partial_symbols X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d1eef86d12f5aa2f8461add1180df9db4b59a39d;p=binutils-gdb.git Introduce objfile::require_partial_symbols This adds a new method, objfile::require_partial_symbols. This reuses most of the code from the old function in psymtab.c. That function is now made static, and simplified. gdb/ChangeLog 2021-03-20 Tom Tromey * symfile.c (read_symbols): Use objfile method. * symfile-debug.c (objfile::require_partial_symbols): New method. * psymtab.h (require_partial_symbols): Don't declare. * psymtab.c (require_partial_symbols): Use objfile method.
