Ok. Thanks.
This is the original issue further reduced:
trippels@gcc2-power8 ~ % cat test2.ii
void
fn1 ()
{ __attribute__ altivec (vector__))) int saijplus16;
((__attribute__ ((altivec (vector__))) int) saijplus16)[0] = 0;
}
trippels@gcc2-power8 ~ % gcc -mvsx -O2 -c test2.ii
test2.ii: In function ‘void fn1()’:
test2.ii:5:1: internal compiler error: in verify_ssa, at tree-ssa.c:939
}
