An error in rbpf

[LiuJun5817]

In this test case, the expected value does not match the output value.

test_interpreter_and_jit_asm!(
        "
        mov32 r0, -1
        add64 r0, 0x1
        exit",
        [],
        (),
        TestContextObject::new(3),
        ProgramResult::Ok(0x0),
    );

interpreter_result is "Ok(0x100000000)", but expected_result is "Ok(0)".
Could the problem be here? "ebpf::MOV32_IMM => self.reg[dst] = insn.imm as u32 as u64,"

[Lichtso]

mov64 reg, imm is what you want here to get i64 sign extension, not mov32 reg, imm as that is limited to u32.
The ISA docs were wrong, so thanks for reporting it.

The patch is in the new repository, as this one is no longer maintained: anza-xyz#10
