Not very surprisingly, I get ICEs at tree-sra.c:2148 when compiling
these two examples with the current trunk at -O[123] on x86-64-linux:
======================================================================
union U
{
double d;
__complex__ int c;
};
double gd;
extern double bar (union U);
double foo (int b, double d, int c1, int c2)
{
union U u;
double r;
if (b)
{
u.d = d;
r = u.d;
}
else
{
__real__ u.c = c1;
__imag__ u.c = c2;
r = bar (u);
}
return r;
}
======================================================================
union U
{
__complex__ int ci;
__complex__ float cf;
};
float gd;
extern float bar (union U);
float foo (int b, double f1, double f2, int c1, int c2)
{
union U u;
double r;
if (b)
{
__real__ u.cf = f1;
__imag__ u.cf = f2;
}
else
{
__real__ u.ci = c1;
__imag__ u.ci = c2;
}
r = bar (u);
return r;
}
======================================================================
Hopefully I know what needs to be done.
