A `gotox rX` instruction accepts only values of type PTR_TO_INSN.
The only way to create such a value is to load it from a map of
type insn_array:
rX = *(rY + offset) # rY was read from an insn_array
...
gotox rX
Add instruction-level and C-level selftests to validate loads
with nonzero offsets.

selftests/bpf: add C-level selftests for indirect jumps2025-11-06T01:53:56+00:00Anton Protopopova.s.protopopov@gmail.com2025-11-05T09:04:10+00:00urn:sha1:ac4d838ce122324b327f69d6de97c96442fcc6ba
Add C-level selftests for indirect jumps to validate LLVM and libbpf
functionality. The tests are intentionally disabled, to be run
locally by developers, but will not make the CI red.
