From: Joseph Myers Date: Tue, 22 Mar 2011 22:49:06 +0000 (+0000) Subject: mep.c (option_mtiny_specified): Remove. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=dd51e35ac7251a9cac90c686790906945ce327d0;p=gcc.git mep.c (option_mtiny_specified): Remove. * config/mep/mep.c (option_mtiny_specified): Remove. (mep_option_override): Move register handling for -mivc2 from mep_handle_option. Use global_options_set.x_mep_tiny_cutoff instead of option_mtiny_specified. (mep_handle_option): Access target_flags via opts pointer. Don't assert that global structures are in use. Defer part of -mivc2 handling and move it to mep_option_override. * config/mep/mep.opt (IVC2): New Mask entry. (mivc2): Use Var and Defer instead of Mask.
