[Bug optimization/15193] New: Unary minus using pointer to V4SF vector causes -fforce-mem to exhaust all memory

["ahu at ds9a dot nl" <gcc-bugzilla at gcc dot gnu dot org>]

Compile the below with gcc chelper-exploit.c -c -O -fforce-mem -msse :
typedef int v4sf __attribute__ ((mode(V4SF)));

void cprocess(v4sf* d_r) 
{
 v4sf force= -(*d_r);
}

And the compiler (cc1) will try to allocate all memory.

Problem disappears with removing the '-', or by switching to 3.3.3 or to the SSA
branche, by removing -O or removing -fforce-mem, by removing -msse
