Bug (?)
2000-07-20 17:12:25 +00:00
This has a split personality. We use expression() to read the
value. We can detect if the value won't fit in a byte or word.
But we can't detect if expression() discarded significant digits
in the case of a long. Not worth the crocks required to fix it. */

/* Select a parser for cons expressions. */
/* Some targets need to parse the expression in various fancy ways.
You can define TC_PARSE_CONS_EXPRESSION to do whatever you like
(for example, the HPPA does this). Otherwise, you can define
BITFIELD_CONS_EXPRESSIONS to permit bitfields to be specified, or
REPEAT_CONS_EXPRESSIONS to permit repeat counts. If none of these
are defined, which is the normal case, then only simple expressions
are permitted. */

A floating constant is defined by atof_generic(), except it is preceded
by 0d 0f 0g or 0h. After observing the STRANGE way my BSD AS does its
reading, I decided to be incompatible. This always tries to give you
rounded bits to the precision of the pseudo-op. Former AS did premature
truncation, restored noisy bits instead of trailing 0s AND gave you

a choice of 2 flavours of noise according to which of 2 floating-point
scanners you directed AS to use.
