[ARM] Peephole optimization ( instructions tst + add )
Ok, thank you, I will implement it then.
As far as I see this optimization should be done in AArch64LoadStoreOptimizer, is it right?

[CodeGen] PeepholeOptimizer: optimizing condition dependent instrunctions
...they produce the same flags as CMP. The bug exists upstream as well.
Together with the fix I want to add some peephole rules for combinations CMP+BRC and CMP+SEL. In the context of optimizeCmpInstr I have all information about CmpInstr. I simply go down and check all instructions which use AArch64::NZCV whether they can be substituted with the simpler version. After all I delete CmpInstr. This approach contradicts with PeepholeOptimizer design because BRC and SEL must be processed in corresponding functions. Yes, 'analyzeCompare' is cheap but in optimizeCondBranch and in optimizeSelect we...

Re-computing Live-in/Live-out Physical Registers for Basic Blocks Using LivePhysRegs
Thank you for your reply!
If liveness of APSR is not tracked, how does the code generator determine whether instructions like cmp are dead code or not?
Is it true that, for every use of APSR (such as a conditional branch), the used def (such as cmp, add, etc.) is always in the same basic block?
Is it true that APSR is never assumed to live across basic block boundaries?
Thank you!
