  • 83b1f2aad   perf annotate browser: More clearly separate columns ... Browse Code »

    The first column (columns in the near future) are for the per line event
    overhead(s), that only appear when they are not zero.

    To clearly separate it, add back a solid vertical line, with just one
    colour, not influenced by the per line overheads.

    Then have the addr/offset column, then optionally the dynamic
    (static in the future) jump->target arrows, if 'j' enables it.

    Then the instructions.

  • a3f895be1   perf annotate browser: Initial loop detection ... Browse Code »

    Simple algorithm, just look for the next backward jump that points to
    before the cursor.

    Then draw an arrow connecting the jump to its target.

    Do this as you move the cursor, entering/exiting possible loops.

    Ex (graph chars replaced to avoid mail encoding woes):

    avc_has_perm_flags
    0.00 | nopl 0x0(%rax)
    5.36 |+-> 68: mov (%rax),%rax
    5.15 || test %rax,%rax
    0.00 || v je 130
    2.96 || 74: cmp -0x20(%rax),%ebx
    47.38 || lea -0x20(%rax),%rcx
    0.28 || ^ jne 68
    3.16 || cmp -0x18(%rax),%dx
    0.00 |+------^ jne 68
    4.92 | cmp 0x4(%rcx),%r13d
    0.00 | v jne 68
    1.15 | test %rcx,%rcx
    0.00 | v je 130

  • 59d038d59   ui browser: Add method to write graphical characters ... Browse Code »

    To save typing on the switch char set slang stuff.

    It also helps in removing more slang direct calls, wrapping them at the
    ui_browser level, where at some point I'll try to implement those in
    terms of GTK+.
