Re: [libvirt] [PATCH 1/2] cfg.mk: override gnulib's undesirable_word_seq check

The regex in gnulib checks if @xref is at the beginning of a sentence, amongst other things. Since we do not use Texinfo and the regex takes almost twice as much as the rest of our checks, use a custom regex without the @xref chcecks. --- I do not know whether the gnulib regex can be optimized: bad_xref_re_ ?= (?:[\w,:;] +|(?:see|also)\s+)\@xref\{ bad_pxref_re_ ?= (?:[.!?]|(?:see|also))\s+\@pxref\{ prohibit_undesirable_word_seq_RE_ ?= \ /(?:\bcan\s+not\b|$(bad_xref_re_)|$(bad_pxref_re_))/gims Either way, we do not need to check for xref in libvirt. cfg.mk | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/cfg.mk b/cfg.mk index 2939458..e7db9a6 100644 --- a/cfg.mk +++ b/cfg.mk @@ -1299,3 +1299,8 @@ exclude_file_name_regexp--sc_prohibit_dt_without_code = \ exclude_file_name_regexp--sc_prohibit_always-defined_macros = \ ^tests/virtestmock.c$$ + +# gnulib's CPU-hungry regex also checks if @xref starts a sequence +# Use a custom regex since we do not use Texinfo +prohibit_undesirable_word_seq_RE_ = \ + /(?:\bcan\s+not\b)/gims
