For an example like below,
extern int do_work(int);
long bpf_helper(void *callback_fn);
long prog() {
return bpf_helper(&do_work);
}
The final generated codes look like:
r1 = do_work ll
call bpf_helper
exit
where we have debuginfo for do_work() extern function:
!17 = !DISubprogram(name: "do_work", ...)
This patch implemented to add additional checking
in processing LD_imm64 operands for possible function pointers
so BTF for bpf function do_work() can be properly generated.
The original llvm function name processReloc() is renamed to
processGlobalValue() to better reflect what the function is doing.
