From: Daniel Jacobowitz Date: Wed, 5 Mar 2003 18:01:46 +0000 (+0000) Subject: * cp-abi.c: Include "command.h", "gdbcmd.h", and "ui-out.h". X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fe1f4a5eb6af1bb69854a55ab42feb74670ae3ce;p=binutils-gdb.git * cp-abi.c: Include "command.h", "gdbcmd.h", and "ui-out.h". (auto_cp_abi): New variable. (current_cp_abi, num_cp_abis): Make static. (CP_ABI_MAX): Define. (cp_abis): Turn into an array. (value_virtual_fn_field): Fix formatting. (switch_to_cp_abi, register_cp_abi): Update. register_cp_abi now takes a pointer. (set_cp_abi_as_auto_default, set_cp_abi_cmd, show_cp_abi_cmd) (list_cp_abis, _initialize_cp_abi): New functions. * cp-abi.h: Add prototype for set_cp_abi_as_auto_default. Remove declarations for cp_abis, num_cp_abis, current_cp_abi, and switch_to_cp_abi. Update prototype for register_cp_abi. * Makefile.in (cp-abi.o): Update dependencies. * minsyms.c (install_minimal_symbols): Call set_cp_abi_as_auto_default instead of switch_to_cp_abi. * gnu-v2-abi.c (_initialize_gnu_v2_abi): Likewise. Update call to register_cp_abi. * gnu-v3-abi.c (_initialize_gnu_v3_abi): Update call to register_cp_abi. * hpacc-abi.c (_initialize_hpacc_abi): Likewise. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index c10c49da546..361fa9e5748 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,28 @@ +2003-03-05 James Ingham + Daniel Jacobowitz + + * cp-abi.c: Include "command.h", "gdbcmd.h", and "ui-out.h". + (auto_cp_abi): New variable. + (current_cp_abi, num_cp_abis): Make static. + (CP_ABI_MAX): Define. + (cp_abis): Turn into an array. + (value_virtual_fn_field): Fix formatting. + (switch_to_cp_abi, register_cp_abi): Update. register_cp_abi now + takes a pointer. + (set_cp_abi_as_auto_default, set_cp_abi_cmd, show_cp_abi_cmd) + (list_cp_abis, _initialize_cp_abi): New functions. + * cp-abi.h: Add prototype for set_cp_abi_as_auto_default.
