Dsrem_mod.S28 | Step 2. Set L := expo(X)-expo(Y), k := 0, Q := 0.
37 | 3.2 If R > Y, then { R := R - Y, Q := Q + 1}
39 | 3.4 k := k + 1, j := j - 1, Q := 2Q, R := 2R. Go to
50 | Q := Q + 1, Y := signY*Y }. Go to Step 6.
51 | 5.3 This is the tricky case of R = Y/2. If Q is odd,
52 | then { Q := Q + 1, signX := -signX }.
58 | Step 8. Return signQ, last 7 bits of Q, and R as required.
60 | Step 9. At this point, R = 2^(-j)*X - Q Y = Y. Thus,
61 | X = 2^(j)*(Q+1)Y. set Q := 2^(j)*(Q+1),
62 | R := 0. Return signQ, last 7 bits of Q, and R.

Dbpf_design_QA.rst2 BPF Design Q&A
18 Q: Is BPF a generic instruction set similar to x64 and arm64?
22 Q: Is BPF a generic virtual machine ?
29 Q: Why C calling convention was chosen?
39 Q: can multiple return values be supported in the future?
43 Q: can more than 5 function arguments be supported in the future?
49 Q: can BPF programs access instruction pointer or return address?
53 Q: can BPF programs access stack pointer ?
62 Q: Does C-calling convention diminishes possible use cases?
74 Q: Does it mean that 'innovative' extensions to BPF code are disallowed?
