Ok for trunk and releases/gcc-14?
--
When the feature "needs_status_wrapper" in dejagnu is used, the
resulting gcc_tg.o file is a regular object file and thus the following
warning will be emitted if doing an incremental link:
.../ld: warning: incremental linking of LTO and non-LTO objects; using
-flinker-output=nolto-rel which will bypass whole program optimization
Since the warning causes test cases, like pr61123-enum-size, to fail,
prune it.
gcc/testsuite/ChangeLog:
* gcc.target/arm/lto/lto.exp: Prune incremental link warning if
status wrapper is used.
