Use the APFloat routines to evaluate FP immediates as
integer constant expressions. The only questionable
thing is that we now reject:
void foo() {
switch (1) {
case (int)1.0e10000:
;
}
}
with:
t.c:5:13: error: case label does not reduce to an integer constant
case (int)1.0e10000:
~~~~~^~~~~~~~~
GCC accepts this, emitting the pedwarn:
t.c:5: warning: floating constant exceeds range of 'double'
