Hi,

Thank you for reporting this Christophe and sorry for the delay. The
scan check obviously will not work for targets that do not optimize
tailcalls. So I applied this patch as obvious in revision r243826, such
that the test also accepts direct non-tailcalls, i.e. 'bl?' rather than 'b'.

The test is really to make sure a direct call is not turned into an
indirect call.

* gcc.target/arm/pr78255-2.c: Fix to work for targets
that do not optimize for tailcall.
