From 63ed81829ea8819bc96b288f95230876b0060b14 Mon Sep 17 00:00:00 2001 From: Patrick Palka Date: Fri, 24 Apr 2015 08:26:50 -0400 Subject: [PATCH] Make type-safe the 'content' field of struct tui_gen_win_info The 'content' field of struct tui_gen_win_info currently has type void ** but the field always stores an object of type tui_win_content. Instead of unnecessarily casting to and from void ** we should just give the field the type tui_win_content in the first place. This patch does this and also eliminates all now-redundant casts involving the 'content' struct field that I could find. gdb/ChangeLog: * tui/tui-data.h (struct tui_win_element): Forward-declare. (tui_win_content): Move declaration. (struct tui_gen_win_info): Give 'content' field the type tui_win_content. * tui/tui-data.c (init_content_element): Remove redundant and erroneous casts. (tui_add_content_elements): Remove erroneous cast. * tui/tui-disasm.c (tui_set_disassem_content): Remove redundant casts. (tui_get_begin_asm_address): Likewise. * tui/tui-regs.c (tui_show_registers): Likewise. (tui_show_register_group): Likewise. (tui_display_registers_from): Likewise.
