+ Adrian + David Hi Arsen, This sounds like a bug to me. Have you tried reproducing it on trunk? For instance, I see that the relation between DICompileUnit and DISubprogram was changed in the meantime (https://reviews.llvm.org/D19034 <https://reviews.llvm.org/D19034>). If this no longer occurs on master you could b...

...efinition in TARGETInstrInfo.td file? May be someone could help with an example? Currently I have seen that we can pass the name of the registers' group, and direct registers as an implicit operands (with Uses or Defs) but I want to pass specific register.

...373 }); 374 } Here I checked that "SPMap.lookup(Scope->getScopeNode());" returns null. If the transformation does right things then probably there is other issue and SPMap[SP] for inlined function should find the main CompileUnit anyway. What do you think about this?

...not contain reference to !69 after optimizations which I think is incorrect. I assume that !69 has not been removed because there are two nodes (!68 and !73) referenced to it as the scope. But that should force the transformations to not remove the link from !12. Is it right? Thank you very much.

...f.then, label %if.else ... during the transformation the %conv is replaced with "double 0x4020333340000000" and then the result of comparison is resolved incorrectly. Is not this a bug?

Dear Tom, What is the advantage to use the “pseudo instruction” approach VS “custom lowering/DAGtoDAGSelection” VS “ Library function”?

...scope of the DISubprogram is null (I assume it should be the DICompileUnit). So I would like to know what would be the correct solution for this issue: Update optimization to not remove reference from the subprograms list, or to skip finding scope in llc.

Hello All, Would anybody explain why there is not direct connection between llvm::Value and metadata nodes. If llvm::Value hold pointer to its MDNode would it cause any malfunctioning?

Hello All, I am interested in Control Dependence Graph building using the CFG and Dominance Frontier provided by corresponding passes.
