From 42edd901a220d9d963d2121d7014b81d43c1ac66 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Thu, 20 Jul 2017 18:04:46 +0100 Subject: [PATCH] Eliminate block_iter_name_* This patch gets rid of block_iter_name_* as being unnecessary. It's the same as calling block_iter_match_*, and passing strcmp_iw as comparison routine. (A later patch will get rid of those new explicit strcmp_iw calls.) gdb/ChangeLog: 2017-07-20 Pedro Alves * block.c (block_iter_name_step, block_iter_name_first) (block_iter_name_next): Delete. (block_lookup_symbol_primary): Adjust to use dict_iter_match_first/dict_iter_match_next. * block.h (block_iter_name_first, block_iter_name_next): Delete declarations. (ALL_BLOCK_SYMBOLS_WITH_NAME): Adjust to use dict_iter_match_first/dict_iter_match_next. --- gdb/ChangeLog | 11 +++++++++ gdb/block.c | 73 ++------------------------------------------------------ gdb/block.h | 24 +++---------------- gdb/dictionary.c | 14 ----------- gdb/dictionary.h | 19 --------------- 5 files changed, 16 insertions(+), 125 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 41e01cd..f6acd34 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,16 @@ 2017-07-20 Pedro Alves + * block.c (block_iter_name_step, block_iter_name_first) + (block_iter_name_next): Delete. + (block_lookup_symbol_primary): Adjust to use + dict_iter_match_first/dict_iter_match_next. + * block.h (block_iter_name_first, block_iter_name_next): Delete + declarations. + (ALL_BLOCK_SYMBOLS_WITH_NAME): Adjust to use + dict_iter_match_first/dict_iter_match_next. + +2017-07-20 Pedro Alves + * cp-support.c (cp_find_first_component_aux): Add missing case for end of string. diff --git a/gdb/block.c b/gdb/block.c index 2f44460..1c343aa 100644 --- a/gdb/block.c +++ b/gdb/block.c @@ -589,75 +589,6 @@ block_iterator_next (struct block_iterator *iterator) return block_iterator_step (iterator, 0); } -/* Perform a single step for a "name" block iterator, iterating across - symbol tables as needed.
