cc015f3abe Allow calling diagnostic_show_locus without a diagnostic_info
Much of diagnostic-show-locus.c currently expects a diagnostic_info *,
but it only uses the rich_location and the diagnostic_t.

Change the signature of diagnostic_show_locus from:

  void
  diagnostic_show_locus (diagnostic_context *,
                         const diagnostic_info *);

to:

  void
  diagnostic_show_locus (diagnostic_context *,
                         rich_location *richloc,
                         diagnostic_t diagnostic_kind);

so that it can be used for things other than diagnostics.

Use this flexibility to add selftests for diagnostic_show_locus.

f87e22c521 selftest.h: add class line_table_test
input.c has a fixture class for running each selftest with a fresh
line_table, and logic for looping over various interesting line_table
test cases.

This patch exposes the above in selftest.h so that such
location-handling tests can be written in other files, renaming the
class from temp_line_table to line_table_test.

Also, the patch moves the stored line table ptr from being a member of
the test class to being a global GC-root, to avoid it being collected
if the GC runs during such a test.

gcc/ChangeLog:
	* input.c (saved_line_table): New global.

80c5ad359f DWARF: do not emit DW_TAG_variable to materialize DWARF procedures
Hello,

For -gdwarf-3 and newer, the DWARF back-end sometimes generates DWARF
procedures to factorize complex location descriptions.  DWARF procedures
can be materialized as DW_TAG_dwarf_procedure DIEs, but actually any DIE
that can hold a DW_AT_location attribute is also accepted.

Unlike what I thought at some point, the DW_TAG_dwarf_procedure tag was
introduced in the DWARFv3 standard, not the DWARFv4 one, so the back-end
can always emit DW_TAG_dwarf_procedure DIEs, as this simplifies code and
prevents the types pruning pass from missing a DWARF procedure.

Boostrapped and regtested on x86_64-linux: no regression.  Ok to commit?
Thank you in advance!

f89b03b6be Evict selftest tempfiles from the diagnostics file cache
Selftests can use class selftest::temp_source_file to write out files
for testing input-handling, and the files are unlinked in the dtor.

This leads to stale entries in input.c's cache of file content, which
could lead to errors if a temporary filename gets reused during a run
of the selftests.

We don't normally expect files to be "deleted from under us", so
special-case this by adding a special way for temp_source_file's
dtor to purge any cache entries referring to it.

gcc/ChangeLog:
	* input.c (diagnostics_file_cache_forcibly_evict_file): New
	function.
	* input.h (diagnostics_file_cache_forcibly_evict_file): New
	declaration.
	* selftest.c (selftest::temp_source_file::~temp_source_file):
	Evict m_filename from the diagnostic file cache.
