Hello, The function ARMBaseInstrInfo::AnalyzeBranch contains the following piece of code: } else if (I->isReturn()) { // Returns can't be analyzed, but we should run cleanup. CantAnalyze = !isPredicated(I); } else { This could lead to cases where for a block that ends with a conditional return, AnalyzeBranch returns false (i.e. analyzed), both TBB and FBB are

Hello Forum, Does any version of asterisk supports Malicious Communication Identification (MCID) using IP standard 3GPP TS 24.616? If yes how can I enable or configure it?

Hi, I had (naively?) expected that the instruction to move immediate to register or memory (such as MOV32mi, MOV32ri, MOV64mi32, MOV64ri, MOV64ri32) would be marked with the flag MCID::MovImm via the X86InstrInfo.td (and hence in the generated X86GenInstrInfo.inc). I do not see that to be the case. Can someone please tell me if my expectation is flawed? Is there a better/different way to determine to test for move immediate to register/memory instruction on X86 other that the...

I found myself wanting a "scheduling barrier" in LLVM. In my specific circumstances I only want it to mean that TargetInstrInfoImpl::isSchedulingBoundary() would return true. I added SchedulingBarrier to MCID in MCInstrDesc.h and pushed it through TD attributes down to isSchedulingBoundary(). Is this something of general interest, or is there another mechanism for implementing barriers that I missed? Thanks -------------- next part -------------- An HTML attachment was scrubbed...

All, TableGen likes to infer the MCID::UnmodeledSideEffects flag from an instruction's pattern. When an instruction doesn't have a pattern, it is assumed to have side effects. It's possible to override this behavior by setting neverHasSideEffects = 1. It was originally the intention that most instructions have patterns, b...

When an instruction doesn't have a pattern, it is assumed to have side effects. Hi Jakob, I don't understand what you're saying.
