Nicolas Cellier uploaded a new version of UpdateStream to project The Trunk: http://source.squeak.org/trunk/UpdateStream-nice.1.mcz ==================== Summary ==================== Name: UpdateStream-nice.1 Author: nice Time: 6 December 2013, 5:07:25.049 pm UUID: 4c14fa26-e847-4f2c-8217-ecb56f016112 Ancestors: Create an UpdateStreamDownloader class to host Utilities class>>'fetching updates' methods. Utilities class side methods are copied as is to UpdateStreamDownloader class side with original authors/stamps The pre-trunk updateFromServer version has been restored.

Eliot Miranda uploaded a new version of Compiler to project The Trunk: http://source.squeak.org/trunk/Compiler-eem.276.mcz ==================== Summary ==================== Name: Compiler-eem.276 Author: eem Time: 3 December 2013, 11:47:59.234 am UUID: e99950e7-3dd5-4d06-9647-f3742bdc5949 Ancestors: Compiler-cmm.275 Access VariableNode's index inst var directly instead of reconstructing it form the code inst var. This removes an artificial limit of 256 temps in any one method. =============== Diff against Compiler-cmm.275 =============== Item was changed: ----- Method: VariableNode>>index (in category 'testing') ----- index + "If index is nil, this code attempts to reconstruct the index from its encoding in code." + index ifNotNil: + [^index]. - "This code attempts to reconstruct the index from its encoding in code." code < 0 ifTrue:[^nil]. code > 256 ifTrue: [self assert: index = (code \\ 256). ^code \\ 256]. code >= (CodeBases at: self type) ifTrue: [self assert: index = (code - (CodeBases at: self type)). ^code - (CodeBases at: self type)]. self assert: index = (code - self type). ^code - self type!
