Create a pass configuration object to be used by addPassToEmitX methods for generating a pipeline of CodeGen passes.

createPassConfig - Create a pass configuration object to be used by addPassToEmitX methods for generating a pipeline of CodeGen passes.

Targets may override this to extend TargetPassConfig.

◆ isMachineVerifierClean()

bool llvm::PPCTargetMachine::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.
