< describing the ways in which this was achieved. I also improved the performance of array assignment, took on a tricky bug that stood in the way of merging a GC performance improvement, and took another small step with the work on escape analysis.
<pre>
5:33 Lots of performance improvements to object initialization
3:24 Make ASSIGN-POS inlineable, improving array assignment
performance; fix an optimization ordering problem while
doing so, which not only helped array assignment
performance, but had wider benefit
3:03 Hunt down and fix a bug introduced by an optimization to
generational GC, allowing the optimization to be merged
1:20 Support scalar replacement of native attribute types in
the upcoming escape analyzer
1:27 Fix problems with how we handled inlinees with multiple
returns, such that they don't violate SSA form; this
allows for more precise analysis of such code, which may
lead to better optimization
1:16 Assorted other debugging/fixing of smaller bugs
Total: 16:03
</pre>
