New Synopsis: [<3.2,3.3,3.4> regression][sparc] Internal compiler error in emit-rtl.c (gen_reg_rxt)
State-Changed-From-To: open->analyzed
State-Changed-By: cae
State-Changed-When: Sun Feb 23 19:08:44 2003
State-Changed-Why:
Confirmed on 3.2, 3.3 and 3.4. This is a regression from 2.95.
A reduced testcase is this:
static int phys_get_long(int addr)
{
if (addr)
return 0;
addr = 0xff000000;
}
struct ieee {
int negative :1 ;
};
double make_single(int value)
{
float result;
struct ieee * srp = (struct ieee *) ( &result );
srp->negative = (value >> 31) & 1;
return result;
}
