This is cumbersome. There is not a way to directly get the std::string or char * representation of IR text?
Directly? No. Take a look at AssemblyWriter::printInstruction() in AsmWriter.cpp. There is a lot of logic involved in generating an accurate, IR-parse-able representation of an instruction. Each operand must be generated in string form which have their own complexities. A string representation of an instruction could perhaps be cached with it, but it would need to be updated every time the instruction is modified -- and not every application of an instruction necessitates having a text version of it.
