octave-libgccjit: libinterp/interpfcn/file-io.cc annotate

annotate libinterp/interpfcn/file-io.cc @ 16590:2d968b7830d6

handle A, R, and W fopen modes correctly (bug #38851) * file-io.cc (normalize_fopen_mode): New function. Handle 'A'. Also handle 'b' and 't' suffixes here. Use Octave:fopen-mode warning id. (fopen_mode_to_ios_mode): Only convert from mode string to ios mode. (do_stream_open): Call normalize_fopen_mode before calling fopen_mode_to_ios_mode. Don't process mode string directly. * io.tst: Update test for fopen modes.
