From ec8e2b6d3051f0b4b2a8eee9917898e95046c62f Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Fri, 14 Jun 2019 23:43:00 +0100 Subject: [PATCH] gdb: Don't allow annotations to influence what else GDB prints The annotations should be additional information printed by GDB to be consumed by users (GUIs), but GDB shouldn't reduce what it prints based on whether annotations are on or not. However, this is what happens for annotate_source_line. This commit makes annotate_source_line a void function that simply outputs the annotation information, GDB will then print the contents of the source line to the terminal in the normal way. Some tests needed to be updated after this commit. gdb/ChangeLog: * annotate.c (annotate_source_line): Change return type to void, update implementation to match. * annotate.h (annotate_source_line): Change return type to void, update header comment. * stack.c (print_frame_info): Don't change what frame information is printed based on whether annotations are on or not. gdb/testsuite/ChangeLog: * gdb.base/annota1.exp: Update expected results. * gdb.cp/annota2.exp: Likewise. * gdb.cp/annota3.exp: Likewise. --- gdb/ChangeLog | 9 +++++ gdb/annotate.c | 8 ++-- gdb/annotate.h | 7 +--- gdb/stack.c | 60 ++++++++++++++---------------- gdb/testsuite/ChangeLog | 6 +++ gdb/testsuite/gdb.base/annota1.exp | 4 +- gdb/testsuite/gdb.cp/annota2.exp | 1 + gdb/testsuite/gdb.cp/annota3.exp | 2 +- 8 files changed, 52 insertions(+), 45 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index f0489df3a5c..d3b9b8d9aee 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,12 @@ +2019-06-15 Andrew Burgess + + * annotate.c (annotate_source_line): Change return type to void, + update implementation to match. + * annotate.h (annotate_source_line): Change return type to void, + update header comment. + * stack.c (print_frame_info): Don't change what frame information + is printed based on whether annotations are on or not. + 2019-06-15 Andrew Burgess * annotate.c: Add 'source.h' and 'objfiles.h' includes. diff --git a/gdb/annotate.c b/gdb/annotate.c index 84f8129b22d..8d8a0196fb0 100644 --- a/gdb/annotate.c +++ b/gdb/annotate.c @@ -434,7 +434,7 @@ annotate_source (const char *filename, int line, int character, int mid, /* See annotate.h. */ -bool +void annotate_source_line (struct symtab *s, int line, int mid_statement, CORE_ADDR pc) { @@ -443,17 +443,15 @@ annotate_source_line (struct symtab *s, int line, int mid_statement, if (s->line_charpos == nullptr) open_source_file_with_line_charpos (s); if (s->fullname == nullptr) - return false; + return; /* Don't index off the end of the line_charpos array. */ if (line > s->nlines) - return false; + return; annotate_source (s->fullname, line, s->line_charpos[line - 1], mid_statement, get_objfile_arch (SYMTAB_OBJFILE (s)), pc); - return true; } - return false; } diff --git a/gdb/annotate.h b/gdb/annotate.h index 9683b7e09ac..5e9f11d6053 100644 --- a/gdb/annotate.h +++ b/gdb/annotate.h @@ -92,11 +92,8 @@ struct annotate_arg_emitter character position.
