Hi Krzystof, regarding your first solution (creating separate instruction), is it possible to somehow have cascading defm? for example, let's suppose aaa is a 3-bit condition a, and bb is a 2-bit condition b, all in one instruction, instead of having one multiclass with 2^5 conditions, is it possible to w...

What is HexagonCommonGEP.cpp for?
I only see Hexagon has such optimization, is there any reason that Hexagon need this? No existing optimization does similar thing?

What is HexagonCommonGEP.cpp for?
Krzystof, Is this partly due to hardware loops not being common? I'm curious, we do something very similar for similar reasons. On Wed, Jun 14, 2017 at 10:23 AM, Krzysztof Parzyszek via llvm-dev < llvm-dev at lists.llvm.org> wrote: > On 6/14/2017 9:05 AM, 陳韋任 wrote: > >> I only...

Many thanks for your prompt reply. I mean, imagine you have 3 bits for condition flags in your instruction (e.g. overflow, zero, carry set, ...) for conditional executions AND there is no direct access to the Status Register, is it even possible to implement such scenario?

Doh. I missed the list in my first reply...
