Target FP: Add conversion routines to target-float.{c,h}
This patch adds the following conversion routines:
- target_float_to_longest
- target_float_from_longest
- target_float_from_ulongest
- target_float_convert
which call the equivalent decimal_ routines to handle decimal FP,
and call helper routines that currently still go via DOUBLEST to
handle binary FP.
The target_float_convert routine not only handles BFP<->BFP and
DFP<->DFP conversions, but also BFP<->DFP, which are implemented
by converting to a string and back.
These helpers are used in particular to implement conversion
from and to FP in value_cast, without going through DOUBLEST there.
In order to implement this for the FP<-integer case, the
pack_long / pack_unsigned_long routines are extended to support
floating-point values as output (thereby allowing use of
value_from_[u]longest with a floating-point target type).
This latter change also allows simplification of value_one.
gdb/ChangeLog:
2017-11-06 Ulrich Weigand <uweigand@de.ibm.com>
* target-float.c (floatformat_to_longest): New function.
(floatformat_from_longest, floatformat_from_ulongest): Likewise.
(floatformat_convert): Likewise.
(target_float_to_longest): Likewise.
(target_float_from_longest, target_float_from_ulongest): Likewise.
(target_float_convert): Likewise.
* target-float.h (target_float_to_longest): Add prototype.
(target_float_from_longest, target_float_from_ulongest): Likewise.
(target_float_convert): Likewise.
* value.c (unpack_long): Use target_float_to_longest.
(pack_long): Allow FP types. Use target_float_from_longest.
(pack_unsigned_long): Likewise using target_float_from_ulongest.
* valops.c: Include "target-float.h". Do not include "dfp.h".
(value_cast): Handle conversions to FP using target_float_convert,
value_from_ulongest, and value_from_longest.
(value_one): Use value_from_longest for FP types as well.
