Re: Igor's fast become for CompiledMethods in Cog

VM Maker: VMMaker.oscog-eem.142.mcz

Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-eem.142.mcz

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

Name: VMMaker.oscog-eem.142
Author: eem
Time: 1 February 2012, 5:51:55.863 pm
UUID: 5b4312fa-5b57-4639-b12d-a45e13e5bbdc
Ancestors: VMMaker.oscog-eem.141

Load function pointer early in ThresdedFFIPlugin's invocation
checking sequence.  This must come early for compatibility with
 the old FFIPlugin.  Image-level code may assume the function
pointer is loaded eagerly.

[commit] r2528 - Load function pointer early in threaded FFI checking sequence, for compatibility

Log:
Load function pointer early in threaded FFI checking sequence, for compatibility
with old FFIPlugin.
Make Qwaq ticker support optional, requiring VM_TICKER to enable.  This to
simplify ticker for older linuxes.
Include Michael Zeder's fixes to revive vm-display-fbdev build on linux.
Avoid assuming readlink supports -f flag on linux builds.

case of overlap, or do you definitely want to change primitive 105?

A new primitive would be prefect. Like this we can even have a nice
fallback in case the VM doesn't have the primitive yet.
