This reduces the execution time of gperf on large inputs by ca. 30%. * autogen.sh (GNULIB_MODULES): Add map-c++, hash-map. * src/keyword.h: Include <stddef.h>. (struct KeywordExt): Add fields _undetermined_chars, _undetermined_chars_length, _undetermined_chars_hashcode. * src/search.cc: Include gl_map.hh, gl_hash_map.h. (Search::prepare_asso_values): Initialize the _undetermined_chars field. (struct EquivalenceClass): Remove the fields _undetermined_chars, _undetermined_chars_length. (undetermined_equals, undetermined_hashcode): New functions. (Search::compute_partition): Initialize the _undetermined_chars* fields of all keywords. Use a hash map instead of a loop over the equivalence classes. (Search::find_good_asso_values): Deallocate the _undetermined_chars field.

# Convenience script for regenerating all autogeneratable files that are
|
|
# omitted from the version control repository. In particular, this script
|
|
# also regenerates all config.h.in, configure files with new versions of
|
|
# autoconf.
|
|
#
|
|
# This script requires autoconf-2.64..2.72 and automake-1.16.4..1.17 in the PATH.

# Prerequisite (if not used from a released tarball): either
|
|
# - the GNULIB_SRCDIR environment variable pointing to a gnulib checkout, or
|
|
# - a preceding invocation of './autopull.sh'.
|
|
#
|
|
# Usage: ./autogen.sh [--skip-gnulib]
|
|
#
|
|
# Options:
|
|
# --skip-gnulib Avoid fetching files from Gnulib.
|
|
# This option is useful
|
|
# - when you are working from a released tarball (possibly
|
|
# with modifications), or
|
|
# - as a speedup, if the set of gnulib modules did not
|
|
# change since the last time you ran this script.
