dw_discr_value Struct Reference

#include <dwarf2out.h>

Data Fields
int	pos
union {
HOST_WIDE_INT   sval
unsigned HOST_WIDE_INT   uval
}	v

Detailed Description

Describe a single value that a discriminant can match.

Discriminants (in the "record variant part" meaning) are scalars.
dw_discr_list_ref and dw_discr_value are a mean to describe a set of
discriminant values that are matched by a particular variant.

Discriminants can be signed or unsigned scalars, and can be discriminants
values.  Both have to be consistent, though.
