From faf28b3a89f32229935b0f60383423315121eb8d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Tobias=20Schl=C3=BCter?= Date: Tue, 17 Apr 2007 18:32:31 +0200 Subject: [PATCH] trans-decl.c (gfc_finish_decl): Remove unused second argument 'init'. * trans-decl.c (gfc_finish_decl): Remove unused second argument 'init'. Simplify code accordingly. Remove calls to gfc_fatal_error in favor of gcc_assert. (create_function_arglist): Remove second argument from calls to gfc_finish-decl. (gfc_trans_dummy_character): Likewise.
