[jira] Created: (HARMONY-5500) [drlvm][jit][opt] IRBuilder
improvement to make it usable in all HLO optimisations
[drlvm][jit][opt] IRBuilder improvement to make it usable in all HLO optimisations
----------------------------------------------------------------------------------
Key: HARMONY-5500
URL: https://issues.apache.org/jira/browse/HARMONY-5500
Project: Harmony
Issue Type: Improvement
Components: DRLVM
Reporter: George Timoshenko
Priority: Minor
This time IRBuilder lives only during translation.
All HLO optimizations creates necessary instructions "manually". And sometimes it is not very convenient.
HLOAPIMagic pass is the best example of such inconvenience. A number of methods for generating instructions into HIR are just copy/pasted there from IRBuilder.
It would be better to make IRBuilder independant from translator and keep it alive during all the HLO so HLOAPIMagic all other passes can use it for instruction creation.

--------------------------------------------
Konstantin,
Egor was wrong in that post.
The issue 5500 has nothing similar with removing simplifier and CSE funtionality from IRBuilder!
IMO these IRBuilder features MUST be kept available even when IRBuilder becomes independent from translator.
By "independence" from translator I mean IRBuilder will live during all HLO stages.
Each HLO pass can configure it (set flags, turn ON or OFF simplification and CSE hashing etc.) and use for HIR instruction creation.
CSE hash must be cleaned when a pass finishes its usage.

--------------------------------------------
Yes, you are right.
For your IRBuilder cleanup you need a separate JIRA issue and probably voting process.

Konstantin Okonechnikov commented on HARMONY-5500:
--------------------------------------------------
George, do I get it right that the only IRBuilder depedence of the translator, is that the translator creates it; and the problem is that IRBuilder is not available in HLO? So there is no need to modify IrBuilder itself (maybe only correct flag behaviour)?
