Try it: ./tools/dump-class ./build/quick/classes
The output is intended to be easy to filter on the command line.
This is a starting point for lots of interesting bytecode analysis
for which we have waited too long.
Example. All generic signatures we produce.
// almost 20K classfiles
% find build/quick/classes -name '*.class' |wc -l
18519
// fully parsed in 6 seconds
tools/dump-class build/quick/classes |grep "^ signature" | wc -l
50802
real 0m6.230s
It's designed to be easy to make faster if you don't care about
particular classfile bits; you can override those methods to jump
forward in the input stream rather than building a structure.
For just a little sampling, here are our most frequently
repeated name/signature combinations.
194 signature <init> ()V // this one is weird, wonder why there's a generic signature
115 signature $div$colon$bslash <A1:Ljava/lang/Object;>(TA1;Lscala/Function2<TA1;TA1;TA1;>;)TA1;
105 signature applyOrElse <A1:Ljava/lang/Object;B1:Ljava/lang/Object;>(TA1;Lscala/Function1<TA1;TB1;>;)TB1;
103 signature view ()Ljava/lang/Object;
101 signature toSet <B:Ljava/lang/Object;>()Lscala/collection/immutable/Set<TB;>;
And the top five name/descriptor combinations.
11170 descriptor <clinit> ()V
10155 descriptor serialVersionUID J
7130 descriptor apply (Ljava/lang/Object;)Ljava/lang/Object;
3028 descriptor apply ()Ljava/lang/Object;
2426 descriptor <init> ()V
