FAQ: Message Sends Inlined by the Compiler
Last updated at 11:15 am UTC on 8 March 2017
Which message sends are inlined by the compiler (i.e. translated directly into byte code)?
Andreas Raab gave the hint to look at the method
MessageNode class>>initialize
The inlined messages are defined as follows (in Squeak 3.8):
MacroSelectors _
#(ifTrue: ifFalse: ifTrue:ifFalse: ifFalse:ifTrue:
and: or:
whileFalse: whileTrue: whileFalse whileTrue
to:do: to:by:do:
caseOf: caseOf:otherwise:
ifNil: ifNotNil: ifNil:ifNotNil: ifNotNil:ifNil:).
In addition, one should look at the class variable StdSelectors of ParseNode. These are translated into special bytecodes, some of which are handled specially by the VM.
