Levente Uzonyi uploaded a new version of Kernel to project The Trunk: http://source.squeak.org/trunk/Kernel-ul.540.mcz ==================== Summary ==================== Name: Kernel-ul.540 Author: ul Time: 29 January 2011, 1:21:18.82 pm UUID: a66e5204-4090-2149-8c6a-d65fa1cc4dd3 Ancestors: Kernel-cmm.539 - updated CompiledMethod's comment as suggested by http://bugs.squeak.org/view.php?id=7570 =============== Diff against Kernel-cmm.539 =============== Item was changed: ByteArray variableByteSubclass: #CompiledMethod instanceVariableNames: '' classVariableNames: 'LargeFrame SmallFrame' poolDictionaries: '' category: 'Kernel-Methods'! + !CompiledMethod commentStamp: 'ul 1/29/2011 13:18' prior: 0! - !CompiledMethod commentStamp: 'ls 7/5/2003 13:48' prior: 0! My instances are methods suitable for interpretation by the virtual machine. This is the only class in the system whose instances intermix both indexable pointer fields and indexable integer fields. + I'm a subclass of ByteArray to avoid duplicating some of ByteArray's methods, not because a CompiledMethod is-a ByteArray. The current format of a CompiledMethod is as follows: header (4 bytes) literals (4 bytes each) bytecodes (variable) trailer (variable) The header is a 30-bit integer with the following format: (index 0) 9 bits: main part of primitive number (#primitive) (index 9) 8 bits: number of literals (#numLiterals) (index 17) 1 bit: whether a large frame size is needed (#frameSize) (index 18) 6 bits: number of temporary variables (#numTemps) (index 24) 4 bits: number of arguments to the method (#numArgs) (index 28) 1 bit: high-bit of primitive number (#primitive) (index 29) 1 bit: flag bit, ignored by the VM (#flag) The trailer has two variant formats. In the first variant, the last byte is at least 252 and the last four bytes represent a source pointer into one of the sources files (see #sourcePointer). In the second variant, the last byte is less than 252, and the last several bytes are a compressed version of the names of the method's temporary variables. The number of bytes used for this purpose is the value of the last byte in the method. !
