Implement CONVERT specifier for OPEN.
This patch, based on Jakub's work, implements the CONVERT
specifier for the power-ieee128 brach. It allows specifying
the conversion as r16_ieee,big_endian and the other way around,
based on a table. Setting the conversion via environment
variable and via program option does not yet work.
gcc/ChangeLog:
* flag-types.h (enum gfc_convert): Add flags for
conversion.
gcc/fortran/ChangeLog:
* libgfortran.h (unit_convert): Add flags.
libgfortran/ChangeLog:
* Makefile.in: Regenerate.
* io/file_pos.c (unformatted_backspace): Mask off
R16 parts for convert.
* io/inquire.c (inquire_via_unit): Add cases for
R16 parts.
* io/open.c (st_open): Add cases for R16 conversion.
* io/transfer.c (unformatted_read): Adjust for R16 conversions.
(unformatted_write): Likewise.
(us_read): Mask of R16 bits.
(data_transfer_init): Likewiese.
(write_us_marker): Likewise.
