Modified gcc.target/arm/naked-1.c testcase
The testcase gcc.target/arm/naked-1.c in the GCC test suite
(https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/testsuite/gcc.target/arm/naked-1.c?view=markup)
contains the following comment:
> /* Check that function arguments aren't assigned and copied to stack slots
> in naked functions. This usually happens at -O0 (presumably for
> better debugging), but is highly undesirable if we haven't created
> a stack frame. */
Modifying this testcase so that the function accepts a struct argument results
in the compiler emitting an instruction sequence to copy function arguments to
the caller's stack frame.
