library/string.m:
Delete procedures that have been marked as obsolete since 2019.
NEWS:
Announce the deletions.
tests/hard_coded/string_append_ooi.m:
tests/hard_coded/string_append_ooi_ilseq.m:
tests/hard_coded/string_presuffix.{m,exp}:
Conform to the above changes.
library/string.m:
Add index_next_repl, unsafe_index_next_repl, prev_index_repl,
unsafe_prev_index_repl predicates that return an indication if a
replacement character was returned because an ill-formed code unit
sequence was encountered.
Add more pragma inlines for indexing predicates.
Remove may_not_duplicate attribute on the Erlang version of
unsafe_prev_index_repl, which would conflict with the pragma inline
declaration. This requires the helper function do_unsafe_prev_index
to be exported.
tests/hard_coded/string_append_ooi_ilseq.m:
tests/hard_coded/string_set_char_ilseq.m:
Use index_next_repl in test cases.
NEWS:
Announce additions.
library/string.m:
Simplify string.append(out, out, in) and make it work sensibly in
the presence of ill-formed code unit sequences, breaking the input
string after each code point or code unit in an ill-formed sequence.
tests/hard_coded/Mmakefile:
tests/hard_coded/string_append_ooi_ilseq.exp:
tests/hard_coded/string_append_ooi_ilseq.exp2:
tests/hard_coded/string_append_ooi_ilseq.m:
Add test case.
