Bug ID: 384337
Summary: performance improvements to VEX register allocator v2
and v3
Product: valgrind
Version: 3.14 SVN
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: vex
Assignee: jsew...@acm.org
Reporter: iv...@ivosh.net
Target Milestone: ---
Philippe did some performance measurements of VEX register allocator v2 and v3
with combination of chasing on/off.
Basically his observations conclude that register allocator v3 is faster to
generate code, but the generated code is less efficient,
and relatively quickly (at around 1 minute), the total becomes worse.
Here are some proof of concepts for some ideas I had how to speed up v2 and v3.
