From 001f13d822104158239fe26a05d9154d967cbe56 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Fri, 19 Apr 2013 15:10:53 +0000 Subject: -Wpointer-sign: gdb_byte -> char. This is sort of the opposite of the previous patch. Places that manipulate strings or interfaces that return strings are changed to use char* instead of gdb_byte*. gdb/ 2013-04-19 Pedro Alves * avr-tdep.c (avr_io_reg_read_command): New local 'bufstr'. Use it to get a string view of the byte buffer. * i386-cygwin-tdep.c (core_process_module_section): Change local 'buf' type to gdb_byte *. Adjust. * linux-tdep.c (linux_info_proc, linux_find_memory_regions_full): Change local to char *. * solib-darwin.c (find_program_interpreter): Change return type to char *. Adjust. (darwin_solib_get_all_image_info_addr_at_init): Adjust. * solib-dsbt.c (enable_break2): Change local 'buf' to char *. * solib-frv.c (enable_break2): Change local 'buf' to char *. * solib-spu.c (spu_current_sos): Add gdb_byte * cast. * solib-svr4.c (find_program_interpreter): Change return type to char *. Adjust. (enable_break): Change local 'interp_name' to char *. * spu-multiarch.c (spu_xfer_partial): Add cast to 'char *'. * spu-tdep.c (spu_pseudo_register_read_spu): Add cast to 'char *'. (spu_pseudo_register_write_spu): Use char for string buffer. Adjust. (info_spu_event_command, info_spu_signal_command): Add casts to 'char *'. --- gdb/ChangeLog | 24 ++++++++++++++++++++++++ gdb/avr-tdep.c | 8 +++++--- gdb/i386-cygwin-tdep.c | 6 +++--- gdb/linux-tdep.c | 4 ++-- gdb/solib-darwin.c | 6 +++--- gdb/solib-dsbt.c | 2 +- gdb/solib-frv.c | 2 +- gdb/solib-spu.c | 2 +- gdb/solib-svr4.c | 6 +++--- gdb/spu-multiarch.c | 2 +- gdb/spu-tdep.c | 16 +++++++++------- 11 files changed, 53 insertions(+), 25 deletions(-) (limited to 'gdb') diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 0c97a68..b1ce7ee 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,29 @@ 2013-04-19 Pedro Alves + * avr-tdep.c (avr_io_reg_read_command): New local 'bufstr'.
