DEC comparisons - allow Hollerith constants in comparisons.
The -fdec option enables the use of Hollerith comparisons in comparisons
with INTEGER, COMPLEX, REAL and CHARACTER expressions.
Mark Eggleston <mark.eggleston@codethink.com>
Jim MacArthur <jim.macarthur@codethink.co.uk>
* gfortran.texi: Update Hollerith constants support for character types
and use in comparisons.
* invoke.texi: Tidy up list of options. Update description of
-fdec-char-conversions.
* resolve.c (is_character_based): New.
(Convert_hollerith_to_character): New. (convert_to_numeric): New.
(resolve_operator): If both sides are character based and -fdec is
enabled convert Hollerith to character. If an operand is Hollerith, the
other is numeric and -fdec is enabled convert to numeric.
(resolve_ordinary_assign): Add check for -fdec-char-conversions for
assignment of character literals.
