Working on the JS engine
Especially working on old branches without some of the nice debugging helpers that jorendorff has implemented, sometimes I look at my gdb session and just know that I’m working on the JS engine:
(gdb) p $.atom
$11 = (JSAtom *) 0xb194f984
(gdb) p/x *(JSString *)((int)$ & ~7)
$12 = {length = 0x20000004, u = {chars = 0xaf434970, base = 0xaf434970}}
(gdb) x/4ch $.u.chars
0xaf434970: 97 'a' 98 'b' 99 'c' 100 'd'
