Subject: [RFA 07/22] Change scoped_minimal_symbol_reader to store objfile
Date: Tue, 27 Sep 2016 04:41:00 -0000	[thread overview]
Message-ID: <1474949330-4307-8-git-send-email-tom@tromey.com> (raw)
In-Reply-To: <1474949330-4307-1-git-send-email-tom@tromey.com>

This changes scoped_minimal_symbol_reader to require the objfile to be
passed to the constructor.  The class now records the objfile and
automatically uses it later in "install".

This is a minor cleanup that will come in useful in the next patch.
It is separate from the first patch to keep that one a bit simpler to
understand.

2016-09-26  Tom Tromey  <tom@tromey.com>

	* xcoffread.c (xcoff_initial_scan): Update.
	* mipsread.c (mipscoff_symfile_read): Update.
	* minsyms.c (scoped_minimal_symbol_reader): Add obj argument.
	Initialize member.
	(install): Remove objfile argument.
	* mdebugread.c (elfmdebug_build_psymtabs): Update.
	* machoread.c (macho_symfile_read): Update.
	* elfread.c (elf_read_minimal_symbols): Update.
	* dbxread.c (dbx_symfile_read): Update.
	* coffread.c (coff_symfile_read): Update.
	* minsyms.h (scoped_minimal_symbol_reader): Add objfile member.
	(constructor): Add objfile argument.
	(scoped_minimal_symbol_reader::install): Remove objfile argument.
