[squeak-dev] decompiler breaks some methods

18 May 2010


      Hello,
while looking at the decompiled code of some OMeta methods I noticed
that the temp name handling in the decompiler seems to be broken.
When you compile a method with temps that are referenced from blocks,
the decompiler tends to rearrange the temp names, so this method
test
    | one two |
    two := 2.
    ^{[one := 1].
    [ [one + two] value]}
gets decompiled to this:
test
    | one two |
    one := 2.
    ^ {[two := 1]. [[two + one] value]}
But that's only a nuisance. The bug really shows up when you decompile a
method compiled using OMeta.
To see what I mean, load the OMeta2 package and have a look at method
OMeta2AndOrOpt>>and.
Cheers,
Hans-Martin
