11:54 < tgrabiec> penberg: there is one problem with basic block splitting inside checkcast. basic blocks are designed to group bytecode instructions so they have 'start' and 'end' bytecode offsets and find_bb returns basic block based on bytecode offset. now if basic block were split inside one instruction (eg. checkcast) then find_bb would be broken because both basic blocks (the main one and the side one) would contain the same instruction
12:46 -!- penberg_home [n=penberg@cs149038.pp.htv.fi] has joined #jato
12:46 < penberg_home> vegard: http://github.com/vegard/jato/commit/20afe03dbc8f95f8f595226949a0e531bc6ba0cf
12:46 < penberg_home> but why?
12:47 < penberg_home> tgrabiec: yeah, seems splitting would be problematic
12:47 < penberg_home> dunno, perhaps INSN_CHECKCAST makes most sense then hmm
12:47 < penberg_home> vegard: there's a patch like that in master already!
12:47 < penberg_home> well
12:47 < penberg_home> I am off
12:48 -!- penberg_home [n=penberg@cs149038.pp.htv.fi] has quit [Client Quit]
12:51 < vegard> penberg: yes, I know :)
12:51 < vegard> you were too slow :-P
12:51 < vegard> penberg: I think your solution was better.
12:52 < vegard> but: I think it's not good to apply the same patch to two trees, if they are to be merged later.
12:56 < vegard> not that we made it any better by doing what we did... ;)
14:24 < vegard> penberg: btw, using dlopen() won't work.
14:24 < vegard> for the simple reason that it relocates the file you're loading
14:24 < vegard> and it also refuses to load just "debug" information or symbol tables
15:08 < vegard> yesss, invokevirtual worrrrrrrksssssss...
15:08 < vegard> which means: all jvm.* tests pass with cafebabe
15:10 < tgrabiec> vegard: splendid :)
15:10 < vegard> it was a stupid mistake on my part that held me back for a long time
15:11 < vegard> so when looking up functions in the class file, I was using strncmp() (because the strings in the file are not null-terminated)
15:11 < vegard> so this caused testArg() to resolve to test() -- oops.
16:22 < vegard> hm, was it true that && operator doesn't work?
16:27 < tgrabiec> vegard: can you paste an example? it seems to work for me
16:41 < vegard> http://pastebin.com/m5b927445
16:41 < vegard> this is in java.lang.String and it crashes :)
16:43 < vegard> but I think it's the s.value.length that crashes, not the &&.
17:06 < tgrabiec> vegard: i've just pulled latest master and i get the following error when executing `make regression`:
17:06 < tgrabiec> make.original: *** Brak reguł do zrobienia obiektu `regression/jato/internal/VM.
17:06 < tgrabiec> which says: "make.original: *** no rules to make object `regression/jato/internal/VM."
17:07 < tgrabiec> can you tell what's wrong ?
17:11 < tgrabiec> probably  "regression/jato/internal/VM.class" is missing in master tree?
17:11 < vegard> hm
17:11 < vegard> do you have VM.java, though?
17:12 < tgrabiec> where ?
17:13 < vegard> regression/jato/internal/VM.java
17:13 < tgrabiec> there is no regression/jato dir
17:13 < vegard> ah
17:14 < vegard> yes, looks like pekka forgot to add it
17:14 < vegard> http://github.com/penberg/jato/commit/8e77031496c368071135133da3758cd99bd69a6a
17:16 < vegard> this should probably be enough: http://pastebin.com/m2e26c8a
17:17 < tgrabiec> vegard: thanks
17:57 < vegard> tgrabiec: you are polish?
17:57 < tgrabiec> vegard: yes
17:58 < vegard> I have been in poland
17:58 < vegard> nowy sacz, I think, without the diacritic marks
17:59 < tgrabiec> i know where it is. it's in the mountain region isn't it ?
18:00 < tgrabiec> what were you doing there ?
18:00 < tgrabiec> i guess it's not the most atractive place for tourists
18:00 < vegard> I don't know. I didn't see mountains there.
18:01 < vegard> I was participating in a competition, the IOI
18:02 < tgrabiec> och, nice
18:03 < vegard> I think it was very nice there
18:03 < vegard> most of all, a lot of friendly people
18:03 < tgrabiec> i've never been to nowy sacz, but probably :)
18:04 < tgrabiec> i'm glad to hear that
18:04 < vegard> in particular, I remember some guys who drove us to the hotel from the university, in the middle of the night
18:05 < vegard> and the receptionists invited us (me and a friend) into their private room.
18:06 < vegard> it was quite nice. and they taught us some polish words, not that I remember much now :)
18:09 < tgrabiec> so, are there any stereotypes about Poles in Norway?
18:11 < vegard> hm
18:12 < vegard> yes
18:14 < vegard> or -- I'm not sure if this is exactly what you mean
18:14 < vegard> it's not very nice. I think that a lot of people only see poles as cheap workers (mostly carpenters)
18:15 < tgrabiec> i could expect that :)
18:19 < vegard> but anyway, I think it is better now than it used to be
