[LLVMdev] bytecode reader assertion failure
I have a compiler transform that I have been working on that produces bytecode that passes the verifier. However, when I try to read that bytecode back in, I get the assertion failure below. llvm::BytecodeReader::ParseConstantPoolValue(unsigned int): Assertion `(!isa<Constant>(Result) || !cast<Constant>(Result)->isNullValue()) || !hasImplicitNull(TypeID) && "Cannot read null values from bytecode!"' failed. So, I ran gdb on opt. I was able to get the following information from opt: (gdb)...
