Re: [Pharo-dev] Some more effort to make Slang and VMMaker work on Pharo [for review]

by Guillermo Polito

Hi Subbu, I do not believe this deserves a paper :P. At most a blogpost. What I can do quickly here is to draft the âmethodologyâ I followed by instinct, but that can be reproduced by anyone. 1) generate sources from pharo 2) try to compile (and run) 3) in case of failure, make a diff with the latest version of the same file in the git repository of opensmalltalk vm 4) spot an interesting difference (most common cases were related to loops and conditions, missing or extra inlinings) => get ONE method with the problem 4.1) Check 1: verify that the generating that method from squeak does **not** have the problem 4.2) Check 2: verify that the generating that method from pharo **does have** the problem For these checks I used some of the already given VMMaker scripts 5) generate a small artificial but representative case for testing. For example: methodWithIfNil self something ifNil: [ 1 ] ifNotNil: [ 2 ] Then I have two level of tests: AST-to-AST transformation, and generation tests. testIfNilIfNotNilBecomesIfTrueIfFalse | translation thisAST | thisAST := (self class >> #methodWithIfNil) ast. translation := thisAST asTranslationMethodOfClass: TMethod. self assert: translation statements first selector equals: #ifTrue:ifFalse: testSimpleIfNilAssignment | translation thisAST codeGenerator result | thisAST := (self class >> #methodWithIfNil) ast. translation := thisAST asTranslationMethodOfClass: TMethod. codeGenerator := CCodeGeneratorGlobalStructure new. codeGenerator generateDeadCode: false. codeGenerator addMethod: translation. codeGenerator doInlining: true. result := String streamContents: [ :stream | translation parseTree statements first emitCCodeOn: stream level: 0 generator: codeGenerator. ]. self assert: result equals: 'if ((something()) == null) { } else { }â 6) Fix it * Most of the âbugsâ were related to making the different #asTranslatorNodeIn: methods in the RB AST compliant to what it was doing in squeak. * Sometimes I ended up doing parallel stepping in Pharo and Squeak to spot where the translation diverged * Something important that Iâve learnt in the process is that Squeakâs AST contain already some transformations/expansions like what you see/write: self x ifNil: [ â¦ ] what you actually have: self x == nil ifTrue: [ â¦ ] BUT, the most confusing point is that even if the AST internally is structured as in the version in the right, the printString of the AST in the inspector showed the left version. Nothing new under the sun ^^.

I did not work on them because the VM seemed to work, so I left them for later: 1) some comments are placed in different places in the output source code. This is entirely cosmetic, but it brings unnecessary noise to C source diffs. 2) labels in the gnuâed code are numbered differently. I did not spot any âbugâ in that yet, I did not dig enough into the gnuification to see why the difference, and Iâm not entirely sure that this difference is caused by that either :)â¦ Anyhow, this is mostly annoying because it also brings lots of noise to diffs. 3) some for loops inline the condition while they probably shouldn't. For example: 0 to: (self numSlotsOf: array1) - 1 do: [ â¦ ] gets in my output translated to for (i = 0; i < (numSlotsOf(array1)); i += 1) { ... while in the version generated from squeak for (i = 0, iLimiT = ((numSlotsOf(array1)) - 1); i <= iLimiT; i += 1) { â¦ This seems the most âdangerous" difference I have so far specially if the limit condition has some side effect.

Perhaps we can move some of the source generation tests into the core. It would be good for there to be tests that apply to the Squeak compiler side too. I never took the time to run tests (I look at the generated source every time I make a change Slang), and writing a really good set of tests always seemed like a lot of work. But I might be tempted to add to the ones you've written. Maybe in the next weeks I can try to massage the tests to make them less dependent on the source (wether squeak's or pharoâs) AST. The thing is that Pharoâs AST is closer to the source code, while Squeakâs has already some pre-cooked code transformations (like #ifNil: & co), and my tests assume a specific AST structure to traverse the tree and compareâ¦ Cheers, Guille

This is super nice and this was a couple of days well invested. I thought that it would be a lot more challenging so you prove it by doing it fast and this is super cool. In addition this is excellent that you added tests while doing it. I really want to have a tutorial on extending the VM with Pharo.
