Detailed Description

Typedef Documentation

LLVMPassBuilderOptionsRef

typedef typedefLLVM_C_EXTERN_C_BEGIN struct LLVMOpaquePassBuilderOptions* LLVMPassBuilderOptionsRef

A set of options passed which are attached to the Pass Manager upon run.

This corresponds to an llvm::LLVMPassBuilderOptions instance

The details for how the different properties of this structure are used can be found in the source for LLVMRunPasses

Definition at line 38 of file PassBuilder.h.

Function Documentation

LLVMCreatePassBuilderOptions()

LLVMPassBuilderOptionsRef LLVMCreatePassBuilderOptions

(

void

)

Create a new set of options for a PassBuilder

Ownership of the returned instance is given to the client, and they are responsible for it. The client should call LLVMDisposePassBuilderOptions to free the pass builder options.

LLVMDisposePassBuilderOptions()

void LLVMDisposePassBuilderOptions

(

LLVMPassBuilderOptionsRef

Options

)

Dispose of a heap-allocated PassBuilderOptions instance

LLVMPassBuilderOptionsSetVerifyEach()

void LLVMPassBuilderOptionsSetVerifyEach	(	LLVMPassBuilderOptionsRef	Options,
		LLVMBool	VerifyEach
	)

Toggle adding the VerifierPass for the PassBuilder, ensuring all functions inside the module is valid.

LLVMRunPasses()

LLVMErrorRef LLVMRunPasses	(	LLVMModuleRef	M,
		const char *	Passes,
		LLVMTargetMachineRef	TM,
		LLVMPassBuilderOptionsRef	Options
	)

Construct and run a set of passes over a module

This function takes a string with the passes that should be used. The format of this string is the same as opt's -passes argument for the new pass manager. Individual passes may be specified, separated by commas. Full pipelines may also be invoked using default<O3> and friends. See opt for full reference of the Passes format.
