findSymbol in optimize layer

[preejackie]

JitFromScratch/SimpleOrcJit.h

Line 127 in 327a6d7

return CompileLayer.findSymbol(mangledName, exportedSymbolsOnly);

in this line findSymbol method is called from the compile layer. Is there any drawback associated if I call findSymbol method on optimize layer ?

Hey preejackie. Layers are organized in a stack and usually they will pass down control-flow. The IRTransformLayer::findSymbol(), I believe, only does that. So, if it sits on top of a IRCompileLayer, semantics shouldn't change. addModule() may have optimized away a function, though ;)
