From 806048c68af789ffb76e44fca706a7915cfdb9aa Mon Sep 17 00:00:00 2001 From: Daniel Jacobowitz Date: Mon, 28 Feb 2005 17:00:49 +0000 Subject: [PATCH] * dwarf2loc.c (loclist_read_variable): Set optimized_out instead of reporting an error. * valprint.c (value_check_printable): New function. (common_val_print): New function. Use value_check_printable. (value_print): Use value_check_printable. * value.h (common_val_print): Add prototype. * c-valprint.c (c_val_print): Use common_val_print. * cp-valprint.c (cp_print_value_fields): Likewise. (cp_print_hpacc_virtual_table_entries): Likewise. * f-valprint.c (f_val_print): Likewise. * jv-valprint.c (java_value_print, java_print_value_fields): Likewise. * scm-valprint.c (scm_value_print): Likewise. * stack.c (print_frame_args): Likewise. * varobj.c (c_value_of_variable): Likewise. * p-valprint.c (pascal_val_print, pascal_value_print): Likewise. (pascal_object_print_value_fields): Likewise. Update call to pascal_object_print_static_field. (pascal_object_print_static_field): Remove TYPE argument.
