Thanks. I don't understand how I can create a trailer with tempNames.
Actually, I don't understand what string to pass as tempNames. In your
#testEmbeddingTempNames you do:
code := 'testEmbeddingSourceCode
| trailer newTrailer code |
trailer := CompiledMethodTrailer new.
trailer sourceCode: code.
newTrailer := trailer testEncoding.
self assert: (newTrailer sourceCode = code).'.
trailer tempNames: code.
But I am not sure if that's correct. What does it means? that as temp names
I send the full source code? I tried and doesn't work.
And then, I read the following method which says something about writing the
tempNames with a particular way:
schematicTempNamesString
"Answer the temp names for the current method node in a form that captures
temp structure. The temps at each method and block scope level occur
space-separated, with any indirect temps enclosed in parentheses. Each
block
level is enclosed in square brackets. e.g.
'method level temps (indirect temp)[block args and temps
(indirect)]'
This representation can be reconstituted into a blockExtentsToTempsMap
by a CompiledMethod that has been copied with the
schematicTempNamesString."
You can also look at CompiledMethodTrailerTest for examples (see
> #testEncoding).

Yeah, I tried it. But maybe I am not seeing something :(
If you want to try it by yourself, just take any Pharo1.3 image like:
https://pharo-ic.lille.inria.fr/hudson/view/Pharo/job/Pharo%201.3/128/artifact/Pharo-1.3.zip
And explore any of the pointers of
((CompiledMethod allInstances select: [:each | each trailer kind =
#VarLengthSourcePointer] ) )
thanks for the effort
