I don't know if this is a regression or not but I think it is. Anyways testcase
compile with -O2 -msse -ffast-math:
#define __vector __attribute__((vector_size(16) ))
__vector float f(void);
void g(__vector float);
void RRB( __vector float vdist, __vector float vx)
{
for(unsigned detail = 0; detail < 5;++detail)
{
__vector float frand = f();
__vector float pullperc = frand/ vdist;
__vector float pullx = vx * pullperc;
g(pullx);
}
}
--- CUT ---
The ICE:
t.cc: In function 'void RRB(float __vector__, float __vector__)':
t.cc:4: error: invalid operand to binary operator
reciptmp.22_1
t.cc:4: note: in statement
# VUSE <reciptmp.22_1> { reciptmp.22 }
pullperc_6 = reciptmp.22_1 * frand_3;
t.cc:4: internal compiler error: verify_stmts failed
