Methods with more than 15 args sketch
by ClÃ©ment Bera June 23, 2016

June 23, 2016

Hi everyone. It seems that some people are struggling with the fact that methods in Pharo (and other Smalltalk on top of Cog) cannot have more than 15 arguments. Typically the problem arises while generating Smalltalk code or porting code from other Smalltalks. I have been thinking for a while about this problem. In this mail I write a small sketch to solve it, it's something that could go to production very quickly and that requires almost only image-side changes. Eliot has already reviewed and approved the sketch, but I''d like to know if someone is strongly against that change. The generic idea is to change the send calling convention at the bytecode level, using a temp vector to pass overflowing arguments. The normal calling convention in the Smalltalk bytecode is as follows: push receiver push arg 1 push arg 2 .... push arg N send selector N is limited to 15 arguments due compiled method header & bytecode encoding. In the new design, if the send has less than 15 arguments, the calling convention remains the same. Over 15 arguments, the overflowing arguments are passed in a temp vector in a similar way to the closure temp vectors. The convention will look like that: push receiver push arg 1 push arg 2 .... push arg N popIntoArray N-15 values send selector The compilation of a method with more than 15 arguments is then changed: - As for temp vectors, the 15th arg array can't be become or read-only, hence the temp vector instructions can be used to access the overflowing arguments through the 15th arg. - the compiled method header is still marked with 15 arguments In addition one needs to change CompiledMethod to: - allow larger frames (instead of 56 we could allow 128 or 256) - have numArgs answering the right number of methods with many arguments. I think the number of arguments could be in the additional method state in this case as it is very uncommon. And to change the fall-back of a couple primitives, such as: - Object>>perform: withArgs: - Object>>perform: withArgs:inSupedClass: - BlockClosure>>valueWithArgs: This design would allow methods to up to 141 arguments. What do you guys think ?

Functional callbacks on all Cog platforms
by Eliot Miranda June 23, 2016

June 23, 2016

Hi All, just wanted to report that as of Alien-eem.35 and https://github.com/OpenSmalltalk/vm/commit/da3fafdec9444754af104e0ed9f613f6… we now have functional callbacks on all x86 platforms, ARM32 platforms and x86_64 platforms. There's a simple example Alien class>>exampleCqsort that shows how to use the system and tests the implementation using the C library's sort quick sort implementation that takes a function pointer as an argument to use for comparing pairs of elements. This is mapped onto a Smalltalk block by Alien's callback implementation. The example sorts 100 random double-precision floats using qsort and a callback into Smalltalk. _,,,^..^,,,_ best, Eliot
