Typedef Documentation

typedef enum llvm_lto_status llvm_lto_status_t

This provides a C-visible enumerator to manage status codes. This should map exactly onto the C++ enumerator LTOStatus.

typedef void* llvm_lto_t

This provides a dummy type for pointers to the LTO object.

Function Documentation

llvm_lto_t llvm_create_optimizer

(

void

)

This provides C interface to initialize link time optimizer. This allows linker to use dlopen() interface to dynamically load LinkTimeOptimizer. extern "C" helps, because dlopen() interface uses name to find the symbol.

void llvm_destroy_optimizer

(

llvm_lto_t

lto

)

llvm_lto_status_t llvm_optimize_modules	(	llvm_lto_t	lto,
		const char *	output_filename
	)

llvm_lto_status_t llvm_read_object_file	(	llvm_lto_t	lto,
		const char *	input_filename
	)
