like this:
void *test(long N) {
return new int[N][42][42];
}
the loop generates two dead mul instructions:
%tmp = load i64* %N.addr ; <i64> [#uses=2]
%0 = mul i64 %tmp, 7056 ; <i64> [#uses=1]
%1 = mul i64 %tmp, 42 ; <i64> [#uses=1]
%2 = mul i64 %1, 42 ; <i64> [#uses=0]
%call = call noalias i8* @_Znam(i64 %0) ; <i8*> [#uses=1]
The scale of these multiplies is already handled by the typesize stuff.
