#
# Here we test for optimizations in the regexp engine.
# We try to distinguish between "nice to have" optimizations and those
# we consider essential: failure of the latter should be considered bugs,
# while failure of the former should at worst be TODO.
#
# Format of data lines is tab-separated: pattern, minlen, anchored, floating,
# other-options, comment.
# - pattern will be subject to string eval as "qr{$pattern}".
# - minlen is a non-negative integer.
# - anchored/floating are of the form "u23:45+string". If initial "u" is
# present we expect a utf8 substring, else a byte substring; subsequent
# digits are the min offset; optional /:\d+/ is the max offset (not
# supported for anchored; assumed undef if not present for floating);
# subsequent '-' or '+' indicates if this is the substring being checked;
# "string" is the substring to expect. Use "-" for the whole entry to
# indicate no substring of this type.
# - other-options is a comma-separated list of bare flags or option=value
# strings. Those with an initial "T" mark the corresponding test TODO.
# Booleans (noscan, isall, skip, implicit, anchor SBOL, anchor MBOL,
# anchor GPOS) are expected false if not mentioned, expected true if
# supplied as bare flags. stclass may be supplied as a pattern match
# as eg "stclass=~^ANYOF".
# - as a special-case, minlenret is expected to be the same as minlen
# unless specified in other-options.
