From 2ba95b9b7657de57799431f196136961875475c9 Mon Sep 17 00:00:00 2001 From: Joel Brobecker Date: Thu, 7 Feb 2008 19:06:51 +0000 Subject: [PATCH] * ada-lang.c: #include "vec.h". (struct string_vector, new_string_vector, string_vector_append): Delete. (char_ptr): New typedef. (DEF_VEC_P (char_ptr)): New VEC type. (symbol_completion_add): Update profile to take the new VEC type instead of the old string_vector structure. Update code accordingly. (ada_make_symbol_completion_list): Use the new VEC type instead of the old string_vector structure, and update the code accordingly. * Makefile.in (ada-lang.o): Add dependency on vec.h. --- gdb/ChangeLog | 13 +++++++++ gdb/Makefile.in | 2 +- gdb/ada-lang.c | 87 +++++++++++++++++++-------------------------------------- 3 files changed, 43 insertions(+), 59 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index eed9485..1299071 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,16 @@ +2007-02-07 Joel Brobecker + + * ada-lang.c: #include "vec.h". + (struct string_vector, new_string_vector, string_vector_append): + Delete. + (char_ptr): New typedef. + (DEF_VEC_P (char_ptr)): New VEC type. + (symbol_completion_add): Update profile to take the new VEC type + instead of the old string_vector structure.
