I'm running into some pretty bad performance in llc.exe when compiling some large neural networks into code that contains some very large llvm::ConstantDataArrays, some are { size=102,760,448 }. There's a small about of actual code for processing the network, but the assembly is mostly global data.

Have you considered just writing out binary data directly and using i.e. .incbin for including it?
