First Bootstrap Milestone Reached
by chevalma＠iro.umontreal.ca 22 Mar '11

22 Mar '11

After a long afternoon of debugging, Erick and I have managed to fix the last bug preventing us from completing the bootstrap. Tachyon can now compile and run this benchmark once bootstrapped. There are still some issues to fix. Notably, we are not compiling the standard library as of now, because the heap size is limited under 32 bits. Still, this is probably a Champagne-worthy victory ;) Once the 64 bit bugs are fixed, we will work on compiling the standard library. With some luck, we might be able to run the shell pretty soon. - Maxime

Mozilla talk converted to beamer
by Bruno Dufour 21 Mar '11

21 Mar '11

I finished converting the talk we gave to Mozilla to beamer. I tried to keep the style of the existing talk as much as possible. The required packages should be installed by default if you have a recent tex distribution. I created a "talks" directory in the main tachyon repository. It is probably a good idea to create your own .tex files in the "slides" directory to minimize conflicts and merging before wednesday. Bruno

Further progress on understanding the bt bridge issue
by Erick Lavoie 19 Mar '11

19 Mar '11

I tried two things in 'initRuntime' from compiler/bootstrap.js in 32 bits: 1. Calling an alternative 'initHeap' function which does nothing to see if the bridge calling was ok. It still crashes. 2. Compare the LIR and ASM code generated for the bridge between the hosted and the bootstrapped version. Here are the findings: The code is identical after the register allocation. It is almost identical after code generation. One small difference is that the 'moves' right before a function call are not exactly in the same order but are still correct. I guess it comes from the fact that I use an object as a hashMap to order moves and that iterating through object properties doesn't give the same result in tachyon and v8. The other difference is that the bytes listing for each instruction gives undefined values instead of numbers. Therefore the bytes in the CodeBlock might be wrong. I'll try printing the Code Block content, byte by byte. For your sheer pleasure, the execution trace follows. Erick PS: The bootstrapped call to initHeap is made to initHeap2, which does nothing but has the same signature as initHeap. time d8 --allow_natives_syntax --nocollect_maps utility/debug.js

typeof f !== "function"
by Marc Feeley 17 Mar '11

17 Mar '11

Tachyon gives: t> function f() { return "hello!"; } t> print(typeof f) object t> print(f instanceof Function) true and V8 gives: d8> function f() { return "hello!"; } d8> print(typeof f) function d8> print(f instanceof Function) true Someone needs to fix that... Marc

Memory allocated bug
by Marc Feeley 17 Mar '11

17 Mar '11

The new performance profiles give strange allocation figures: Compiling Tachyon: 484.539 s, 0 MB allocated time=84% alloc=NaN% -- Machine code generation time=46% alloc=NaN% -- Linear scan time=20% alloc=NaN% -- Resolution time=10% alloc=NaN% -- IR to ASM translation time=2% alloc=NaN% -- Computing live intervals time=1% alloc=NaN% -- Assembly time=1% alloc=NaN% -- Operand assignment time=0% alloc=NaN% -- Number instructions time=0% alloc=NaN% -- Computing fixed intervals time=0% alloc=NaN% -- Order blocks time=13% alloc=NaN% -- IR lowering time=1% alloc=NaN% -- IR generation time=0% alloc=NaN% -- Machine code linking time=0% alloc=NaN% -- Parsing There must be a bug in memAllocatedKB . Moreover, shouldn't there be 2 versions of this procedure? One reporting the allocations on the V8 heap, and the other on the Tachyon heap? Marc

More progress... need 64 bits or a GC!
by Marc Feeley 17 Mar '11

17 Mar '11

I commented out the test for "function" in x86/asm.js : x86.Assembler.prototype.linked = function (name, linkValue, width) { var that = Object.create(x86.Assembler.prototype.linked.prototype); assert(typeof(name) === "string", "'name' argument must be a string"); // assert(typeof(linkValue) === "function", "'linkValue' argument must be a function"); assert(typeof(width) === "number", "'width' argument must be a number"); that.name = name; that.linkValue = linkValue; that.width = function () { return width; }; return that; }; Now the bootstrap goes even further... and hits a heap overflow: ... Performing IR lowering for: "runtime/ffi.js" Performing IR lowering for: "runtime/rtinit.js" Generating machine code for: "object layout source" Performing garbage collection Entering gcCollect Context pointer = 0x4eeb000 Leaving gcCollect *** RUN-TIME ERROR *** allocation exceeds heap limit Erick... is the x86-64 backend good enough to run Tachyon on baro with lots of memory?

Predoc Skeleton
by chevalma＠iro.umontreal.ca 17 Mar '11

17 Mar '11

I'm working on a little sketch of my predoc report and would like some feedback. I'm just trying to establish an outline of what I will be discussing. As such, I wrote a table of contents and I've begun to gather a bibliography of papers that I will probably mention in my related work section. Could you take a look and make suggestions to improve it? Do you think that there are things missing from the outline, or that I should organize things differently? Can you think of other papers I should be citing? I think that perhaps tracing JITs deserve a section just for them under related work, seeing the large amount of publications about them. - Maxime
