[Vm-dev] VM Maker: VMMaker.oscog-eem.798.mcz

[commits at source.squeak.org]

Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-eem.798.mcz

==================== Summary ====================

Name: VMMaker.oscog-eem.798
Author: eem
Time: 3 July 2014, 6:06:32.954 am
UUID: f47e2c22-fea0-4762-b689-8b295a59d8ac
Ancestors: VMMaker.oscog-eem.797

Sort VM methods by class first, selector second, to group
by coarse functionality (e.g. scavenger methods) for the
benefit of the VMProfiler.

Access missOffset via a macro (very minor speedup).

  sortMethods: aTMethodCollection
  	"We need to define this since different Squeak versions answer different results
+ 	 for asSortedCollection and if sort order changes, generated code changes too.
+ 	 When generating VM code, use class name as major sort index as this groups
+ 	 some methods by functionality (e.g. SpurGenerationScavenger) and that makes
+ 	 the VMProfiler more useful."
