    PR c/59905
    * c-typeck.c (build_function_call_vec): Do not replace calls
    to a function via an incompatible type with a runtime abort.

    * gcc.dg/cast-function-1.c: Adjust to survive DCE.
    * gcc.dg/call-diag-2.c: Remove expected warnings about calling
    abort.
    * gcc.dg/invalid-call-1.c: Likewise.
