/* This tests strength reduction and choice of induction variables. The targets for this testcase are quite limited, as with different set of available addressing modes, the results may be quite different. The testcase comes from PR 29256 (and originally, the stream benchmark). */ /* { dg-do compile { target i?86-*-* x86_64-*-* powerpc*-*-*} } */ /* { dg-options "-O3 -fdump-tree-final_cleanup" } */ # define N 2000000 static double a[N],c[N]; void tuned_STREAM_Copy() { int j; for (j=0; j<N; j++) c[j] = a[j]; } /* Check that the memory references are based on &a and &c, with appropriate offsets.
