    ERROR: gcc.dg/tree-ssa/return-value-range-1.c: 1: syntax error for " dg-do 1 ling "

With that fixed into 'dg-do link', and...

> +/* { dg-options "-O1 -dump-tree-evrp-details" } */

... that one fixed into '-fdump-tree-evrp-details', I then get:

    FAIL: gcc.dg/tree-ssa/return-value-range-1.c (test for excess errors)
    UNRESOLVED: gcc.dg/tree-ssa/return-value-range-1.c scan-tree-dump-times evrp "Recording return range" 2

    /tmp/ccTEuffl.o: In function `test':
    return-value-range-1.c:(.text+0x24): undefined reference to `link_error'

This disappears when switching from '-O1' to '-O2'.  OK to push the
attached "Fix 'gcc.dg/tree-ssa/return-value-range-1.c'"?  (..., or did
you intend something else, here?)
