Bug ID: 381553
Summary: VEX register allocator v3
Product: valgrind
Version: 3.13 SVN
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: vex
Assignee: jsew...@acm.org
Reporter: iv...@ivosh.net
Target Milestone: ---
Julian Seward designed new VEX register allocator last year.
And here is its initial implementation.
On amd64/Linux, it manages to allocate 385 superblocks while running
"/bin/true" until it bombs out for some reason.
There are still a few missing features to implement.
However it is believed that compared to the previous register allocator v2 it
is:
- simpler
- faster
- perhaps producing slightly worse spilling decisions
