gcc/ChangeLog:

* diagnostic-show-locus.c (struct line_span): New struct.
(layout::get_first_line): Delete.
(layout::get_last_line): Delete.
(layout::get_num_line_spans): New member function.
(layout::get_line_span): Likewise.
(layout::print_heading_for_line_span_index_p): Likewise.
(layout::get_expanded_location): Likewise.
(layout::calculate_line_spans): Likewise.
(layout::m_first_line): Delete.
(layout::m_last_line): Delete.
(layout::m_line_spans): New field.
(layout::layout): Update comment. Replace m_first_line and
m_last_line with m_line_spans, replacing their initialization
with a call to calculate_line_spans.
(diagnostic_show_locus): When printing source lines and
annotations, rather than looping over a single span
of lines, instead loop over each line_span within
the layout, with an inner loop over the lines within them.
Call the context's start_span callback when changing line
spans.
* diagnostic.c (diagnostic_initialize): Initialize start_span.
(diagnostic_build_prefix): Break out the building of the
location
part of the string into...
(diagnostic_get_location_text): ...this new function, rewriting
it from nested ternary expressions to a sequence of "if"
statements.
(default_diagnostic_start_span_fn): New function.
* diagnostic.h (diagnostic_start_span_fn): New typedef.
(diagnostic_context::start_span): New field.
(default_diagnostic_start_span_fn): New prototype.

* lib/gfortran-dg.exp (proc gfortran-dg-test): Update comment
to
distinguish between the caret-printing and non-caret-printing
cases. If caret-printing has been explicitly enabled, bail out
without attempting to fix up the output.

Umm, does that allocate 1 + rich_location::MAX_RANGES linespans?
+ auto_vec<line_span> tmp_spans (1 + rich_location::MAX_RANGES);
Similarly.
Yes, it's preallocating space in the vecs. rich_location::MAX_RANGES
is 3, so there can be at most 4 line spans to consider.
Ah, nevermind then. If it's just 4, then I'm not worried.
OK for the trunk.
