[llvm-commits] [patch] ARM liveness bug PR14356

[Tim Northover]

Hi Jakob,

Agreed. I'd taken an extremely local look for this issue. I think the
attached patch fixes these issues by giving defines precedence over
uses of a register when looking upwards (and I've made sure the
reverse is the case when searching downwards). I'm also reasonably
sure we check for all relevant fields now.

Ok to commit?

Tim.
