    • Fix -Wmisleading-indentation false-positive · d5398058 
      gcc/c-family/ChangeLog:

	* c-indentation.c (should_warn_for_misleading_indentation):
	Float out and consolidate the calls to get_visual_column that
	are passed guard_exploc as an argument.  Compare
	next_stmt_vis_column with guard_line_first_nws instead of with
	body_line_first_nws.

gcc/testsuite/ChangeLog:

	* c-c++-common/Wmisleading-indentation.c: Augment test.

    • shrink-wrap: Handle multiple predecessors of prologue · 6c98d499 
      The caller of try_shrink_wrapping wants to be returned a single edge to
put the prologue on.  To make that work even if there are multiple edges
(all pointing to the PRO block) that need the prologue, add a new block
that becomes the destination of all such edges, and then jumps to PRO.

In the general case, some edges to PRO will need to be redirected, and
not all edges *can* be redirected.  This adds a can_get_prologue function
that detects such cases.  This then happily can also handle the "prologue
clobbers some reg that is live on the edge we want to insert it on" case.

Not all EDGE_CROSSING edges can be redirected, so handle those the same
as EDGE_COMPLEX edges.

	* function.c (thread_prologue_and_epilogue_insns): Delete
	orig_entry_edge argument to try_shrink_wrapping.
	* shrink-wrap.c (can_get_prologue): New function.
	(can_dup_for_shrink_wrapping): Also handle EDGE_CROSSING.
	(try_shrink_wrapping): Delete orig_entry_edge argument.  Use
	can_get_prologue where needed.  Remove code that finds a single
	edge for the prologue.  Remove code that tests if any reg clobbered
	by the prologue is live on the prologue edge.  Remove code that finds
	the new prologue edge after duplicating blocks.  Make a new prologue
	block and edge.
	* shrink-wrap.h (try_shrink_wrapping): Delete orig_entry_edge argument.

    • [PATCH tree-inline] Do not say "called from here" with UNKNOWN_LOCATION · 9915b1c9 
      In https://sourceware.org/ml/libc-alpha/2014-12/msg00300.html, we give a
"called from here" note without actually having a location, which looks
strange. I haven't been able to generate such a testcase. If this happens,
try to at least point to the current function being called. If that location is
also unknown, skip the extra note.
