    • LTO-wrapper, don't pre-link early debug objects. · b5327e50 
      Pass them to the final link, the pre-link wasn't effective.
Make the temp filenames easier to follow.
Also save them in the CWD when save-temps is given.

2018-12-23  Iain Sandoe  <iain@sandoe.co.uk>

	* lto-wrapper.c (tool_cleanup): Don’t report ficticious temp files.
	(debug_objcopy): Improve temp filenames.  Append the early
	debug objects to the outfiles.  Remove the phase prelinking the
	early debug. Emit the early debug filenames for ld.

    • Fix ident tests by Enabling ident output for X86 Darwin. · d590d99a 
      The c-c++-common tests fail (or XPASS depending on which) on Darwin
because it doesn't currently emit .ident marker.  For X86 Darwin, this
is a trivial oversight; the assembler supports the directive.  We can
therefore use the default target hook there.

    • use simple-object instead of nm to determine if files contain LTO. · 4098a6d4 
      This replaces the use of nm to search for the LTO common symbol marker
and uses simple object to see if there's a section starting with
".gnu.lto_." or ".gnu.offload_lto_"

2018-12-23  Iain Sandoe  <iain@sandoe.co.uk>

	* collect2.c (maybe_run_lto_and_relink): Don’t say we have a temp file
	unless we actually did some LTO.
	(has_lto_section, is_lto_object_file): New.
	(maybe_lto_object_file): Remove.
	(scan_prog_file): Use is_lto_object_file() instead of scanning the
	output of nm.

    • Handle -save-temps in collect2 · 513825f0 
      Handle the option, make the saved filenames and paths easier to handle.
Don't print '[Leaving...]' for files we never created and don't exist - or unless
verbose is true.

2018-12-23  Iain Sandoe  <iain@sandoe.co.uk>

	* collect2.c (main): Parse the output file early so we can make nicer
	temp names.  Respond to “-save-temps” in the GCC OPTIONS.
	(maybe_unlink): Don’t print “[Leaving…”] for files we never created
	and don’t exist.

    • Ensure collect2 responds to intended commmand line options. · f67eeb79 
      To ensure compatibility with the flags consumed by ld, some of the flags
needed by collect2 come from the command line and some are passed
in the COLLECT_GCC_OPTIONS.

Here we combine initial parses of both and then set the LTO mode accordingly.

2018-12-23  Iain Sandoe  <iain@sandoe.co.uk>

    • [ARM] Fix size-optimization-ieee testcase failure · 7fa344c5 
      On some version of dejagnu, options in RUNTESTFLAGS are appended to the
command-line and thus any -mfloat-abi=softfp or -mfloat-abi=hard in
there overwrite the -mfloat-abi=soft in the dg-options for
size-optimization-ieee-* tests. Test is still run though because
arm_soft_ok returns true if -mfloat-abi=soft is accepted, even if the
file is not compiled for softfloat due to a later -mfloat-abi on the
command line.

This patch adds a dg-skip-if to those tests to ensure they are not run
in softfp or hard mode.
