Support prefixes in diagnostic_show_locus
Previously, diagnostic_show_locus saved and restored the pretty_printer's
prefix, clearing it for the duration of the call.
I have a patch kit in development that can benefit from applying a prefix
to the output of d_s_l, so this patch adds support to d_s_l for printing
such prefixes.
It moves the save and restore of the pp's prefix from d_s_l to all of its
callers, and updates diagnostic-show-locus.c to properly handle prefixes.
gcc/c-family/ChangeLog:
* c-opts.c (c_diagnostic_finalizer): Temporarily clear prefix when
calling diagnostic_show_locus, rather than destroying it afterwards.
gcc/ChangeLog:
* diagnostic-show-locus.c (layout::print_gap_in_line_numbering):
Call pp_emit_prefix.
(layout::print_source_line): Likewise.
(layout::start_annotation_line): Likewise.
(diagnostic_show_locus): Remove call to temporarily clear the
prefix.
(selftest::test_one_liner_fixit_remove): Add test coverage for the
interaction of pp_set_prefix with rulers and fix-it hints.
* diagnostic.c (default_diagnostic_finalizer): Temporarily clear
prefix when calling diagnostic_show_locus, rather than destroying
it afterwards.
(print_parseable_fixits): Temporarily clear prefix.
* pretty-print.c (pp_format): Save and restore line_length, rather
than assuming it is zero.
(pp_output_formatted_text): Remove assertion that line_length is
zero.
gcc/fortran/ChangeLog:
* error.c (gfc_diagnostic_starter): Clear the prefix before
calling diagnostic_show_locus.
gcc/testsuite/ChangeLog:
* gcc.dg/plugin/diagnostic_group_plugin.c (test_begin_group_cb):
Clear the prefix before emitting the "END GROUP" line.
* gcc.dg/plugin/diagnostic_plugin_test_show_locus.c
(custom_diagnostic_finalizer): Temporarily clear prefix when
calling diagnostic_show_locus, rather than destroying it
afterwards.
