From 2712ce2e659f82168154d4533f53d2963ae82571 Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sun, 15 Oct 2017 11:13:29 -0600 Subject: [PATCH] Introduce new_bfd_ref This introduces a helper function, new_bfd_ref, that calls gdb_bfd_ref and returns a gdb_bfd_ref_ptr. Then it updates several places to use this. ChangeLog 2017-10-20 Tom Tromey * exec.c (exec_file_attach): Use new_bfd_ref. * symfile-mem.c (symbol_file_add_from_memory): Use new_bfd_ref. * gdb_bfd.c (gdb_bfd_open, gdb_bfd_fopen, gdb_bfd_openr) (gdb_bfd_openw, gdb_bfd_openr_iovec, gdb_bfd_fdopenr): Use new_bfd_ref. * gdb_bfd.h (new_bfd_ref): New function. --- gdb/ChangeLog | 9 +++++++++ gdb/exec.c | 3 +-- gdb/gdb_bfd.c | 31 +++++++------------------------ gdb/gdb_bfd.h | 10 ++++++++++ gdb/symfile-mem.c | 3 +-- 5 files changed, 28 insertions(+), 28 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index a5107f7..81b70c1 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,12 @@ +2017-10-20 Tom Tromey + + * exec.c (exec_file_attach): Use new_bfd_ref. + * symfile-mem.c (symbol_file_add_from_memory): Use new_bfd_ref. + * gdb_bfd.c (gdb_bfd_open, gdb_bfd_fopen, gdb_bfd_openr) + (gdb_bfd_openw, gdb_bfd_openr_iovec, gdb_bfd_fdopenr): Use + new_bfd_ref. + * gdb_bfd.h (new_bfd_ref): New function. + 2017-10-20 Pedro Alves * main.c (captured_command_loop): Add attribute noinline. diff --git a/gdb/exec.c b/gdb/exec.c index 2fa543b..326cfff 100644 --- a/gdb/exec.c +++ b/gdb/exec.c @@ -248,8 +248,7 @@ exec_file_attach (const char *filename, int from_tty) /* First, acquire a reference to the current exec_bfd.
