fortran: Extend -fconvert= option for ppc64le r16_ieee and r16_ibm
This patch on top of the previously posted option handling changes patch
allows specifying -fconvert=swap,r16_ieee etc. (but will error on it
when not on powerpc64le because in the library such swapping is only
implemented for HAVE_REAL_17).
2022-01-24 Jakub Jelinek <jakub@redhat.com>
* lang.opt (fconvert=): Add EnumSet property and mention also
r16_ieee and r16_ibm arguments.
(big-endian, little-endian, native, swap): Add Set(1) property.
(r16_ieee, r16_ibm): New EnumValue entries with Set(2) property.
* trans-types.cc (gfc_init_kinds): Emit gfc_fatal_error for
-fconvert=r16_ieee or -fconvert=r16_ibm when R16_IEEE <=> R16_IBM
conversions aren't supported.
