From: Bob Wilson Date: Wed, 10 Sep 2003 00:17:29 +0000 (+0000) Subject: * config/tc-xtensa.c (xtensa_mark_literal_pool_location): Remove X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=a057a19d302777cc73416b37340c8533d55528d7;p=pf3gnuchains%2Fpf3gnuchains3x.git * config/tc-xtensa.c (xtensa_mark_literal_pool_location): Remove "move_labels" argument and corresponding call to xtensa_move_labels. (md_assemble): Add a separate call to xtensa_move_labels and remove argument for call to xtensa_mark_literal_pool_location. (xtensa_literal_position, xtensa_switch_to_literal_fragment): Fix calls to xtensa_mark_literal_pool_location. (xtensa_create_local_symbol): Delete and inline the code into... (xtensa_create_literal_symbol): ...here. (xtensa_frob_label): Combine conditionals.
