[PATCH bpf-next v2 0/5] bpftool: Add inline annotations when dumping program CFGs

[Quentin Monnet <quentin@isovalent.com>]

This set contains some improvements for bpftool's "visual" program dump
option, which produces the control flow graph in a DOT format. The main
objective is to add support for inline annotations on such graphs, so that
we can have the C source code for the program showing up alongside the
instructions, when available. The last commits also make it possible to
display the line numbers or the bare opcodes in the graph, as supported by
regular program dumps.

v2: Replace fputc(..., stdout) with putchar(...) in dotlabel_puts().

Quentin Monnet (5):
  bpftool: Fix documentation about line info display for prog dumps
  bpftool: Fix bug for long instructions in program CFG dumps
  bpftool: Support inline annotations when dumping the CFG of a program
  bpftool: Support "opcodes", "linum", "visual" simultaneously
  bpftool: Support printing opcodes and source file references in CFG
