I don't think it is a good idea to significantly change the function being
tested. Then it tests completely different thing from what it is meant to
test.
But in the pr36728-{1,2}.c case, perhaps you could instead change the
caller, by adding
asm volatile ("" : : "r" (l));
before return 0; in main, that way DW_OP_GNU_entry_value could work if there
is no other way to find the value of the arguments, because l will need to
live somewhere (in some register or memory) across the foo call.
