Add passes to the specified pass manager to get machine code emitted with the MCJIT.

addPassesToEmitMC - Add passes to the specified pass manager to get machine code emitted with the MCJIT.

This method returns true if machine code is not supported. It fills the MCContext Ctx pointer which can be used to build custom MCStreamer.

◆ isMachineVerifierClean()

bool llvm::NVPTXTargetMachine::isMachineVerifierClean ( ) const

Returns true if the target is expected to pass all machine verifier checks.

This is a stopgap measure to fix targets one by one. We will remove this at some point and always enable the verifier when EXPENSIVE_CHECKS is enabled.
