From 1831a9f9d3346dbf61202d2aba6935f0093487dd Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sun, 29 Apr 2018 21:02:19 -0600 Subject: Remove new_bfd_ref For gdb_bfd_ref_ptr, gdb already had a convenience function like the new gdb_ref_ptr::new_reference -- called new_bfd_ref. This patch removes it in favor of the new common function. While doing this I also noticed that the comment for gdb_bfd_open was incorrect (in a way related to reference counting), so this patch updates the comment as well. ChangeLog 2018-04-30 Tom Tromey * symfile-mem.c (symbol_file_add_from_memory): Use new_reference. * gdb_bfd.h (new_bfd_ref): Remove. (gdb_bfd_open): Update comment. * gdb_bfd.c (gdb_bfd_open, gdb_bfd_fopen, gdb_bfd_openr) (gdb_bfd_openw, gdb_bfd_openr_iovec, gdb_bfd_record_inclusion) (gdb_bfd_fdopenr): Use new_reference. * exec.c (exec_file_attach): Use new_reference. --- gdb/ChangeLog | 10 ++++++++++ gdb/exec.c | 2 +- gdb/gdb_bfd.c | 16 ++++++++-------- gdb/gdb_bfd.h | 25 +++++++------------------ gdb/symfile-mem.c | 2 +- 5 files changed, 27 insertions(+), 28 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index b65ec81..7da8ca3 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,15 @@ 2018-04-30 Tom Tromey + * symfile-mem.c (symbol_file_add_from_memory): Use new_reference. + * gdb_bfd.h (new_bfd_ref): Remove. + (gdb_bfd_open): Update comment. + * gdb_bfd.c (gdb_bfd_open, gdb_bfd_fopen, gdb_bfd_openr) + (gdb_bfd_openw, gdb_bfd_openr_iovec, gdb_bfd_record_inclusion) + (gdb_bfd_fdopenr): Use new_reference. + * exec.c (exec_file_attach): Use new_reference. + +2018-04-30 Tom Tromey + * common/gdb_ref_ptr.h (ref_ptr::new_reference): New static method. diff --git a/gdb/exec.c b/gdb/exec.c index f94c15f..b529b7a 100644 --- a/gdb/exec.c +++ b/gdb/exec.c @@ -246,7 +246,7 @@ exec_file_attach (const char *filename, int from_tty) /* First, acquire a reference to the current exec_bfd.
