From 276d885b572b12221f639641846ab94ef9582995 Mon Sep 17 00:00:00 2001 From: Gary Benson Date: Sat, 31 Jan 2015 14:45:26 -0800 Subject: [PATCH] new callback parameter expansion_notify for expand_symtabs_matching This commit adds a new callback parameter, "expansion_notify", to the top-level expand_symtabs_matching function and to all the vectorized functions it defers to. If expansion_notify is non-NULL, it will be called every time a symbol table is expanded. gdb/ChangeLog: * symfile.h (expand_symtabs_exp_notify_ftype): New typedef. (struct quick_symbol_functions) : New argument expansion_notify. All uses updated. (expand_symtabs_matching): New argument expansion_notify. All uses updated. * symfile-debug.c (debug_qf_expand_symtabs_matching): Also print expansion notify. * symtab.c (expand_symtabs_matching_via_partial): Call expansion_notify whenever a partial symbol table is expanded. * dwarf2read.c (dw2_expand_symtabs_matching): Call expansion_notify whenever a symbol table is instantiated. --- gdb/ChangeLog | 14 ++++++++++++++ gdb/ada-lang.c | 6 +++--- gdb/dwarf2read.c | 16 +++++++++++++++- gdb/linespec.c | 2 +- gdb/psymtab.c | 9 ++++++++- gdb/symfile-debug.c | 5 ++++- gdb/symfile.c | 4 +++- gdb/symfile.h | 8 ++++++++ gdb/symmisc.c | 2 +- gdb/symtab.c | 6 +++--- 10 files changed, 60 insertions(+), 12 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 33e0dffddc..d97b9c4e3a 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,17 @@ +2015-01-31 Gary Benson + + * symfile.h (expand_symtabs_exp_notify_ftype): New typedef. + (struct quick_symbol_functions) : + New argument expansion_notify.
