Is there a way to express a requirement that a single line cause

Sure, and it is used many times in the testsuite.
whatever; /* { dg-error "whatever1" } */
/* { dg-error "whatever2" "" { target *-*-* } 33 } */
You need to use the target specification and supply line number in the
second and following directive which you want to apply to the same line.
Thanks! I'd seen this pattern but completely forgot about it.
Let me update the Wiki.
Btw., the above works fine when each directive is on its own line
but when the second follows the first on the same line (somehow
I thought it needed to be at first), the second one needs another
string argument. I haven't looked into what it's for but the regex
is the second argument in this case, not the first. Like this:
whatever; // { dg-error "regex-1" } { dg-error "???" "regex2" "fail
message" { target-selector } <line-number> }
