LLVM-C: C interface to LLVM
Collaboration diagram for Link Time Optimization:

Typedefs

typedef void * llvm_lto_t
 This provides a dummy type for pointers to the LTO object.
typedef enum llvm_lto_status llvm_lto_status_t
 This provides a C-visible enumerator to manage status codes.

Enumerations

enum  llvm_lto_status {
  LLVM_LTO_UNKNOWN, LLVM_LTO_OPT_SUCCESS, LLVM_LTO_READ_SUCCESS, LLVM_LTO_READ_FAILURE,
  LLVM_LTO_WRITE_FAILURE, LLVM_LTO_NO_TARGET, LLVM_LTO_NO_WORK, LLVM_LTO_MODULE_MERGE_FAILURE,
  LLVM_LTO_ASM_FAILURE, LLVM_LTO_NULL_OBJECT
}
 This provides a C-visible enumerator to manage status codes. More...

Functions

llvm_lto_t llvm_create_optimizer (void)
 This provides C interface to initialize link time optimizer.

Typedef Documentation

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.

Enumeration Type Documentation

This provides a C-visible enumerator to manage status codes.

This should map exactly onto the C++ enumerator LTOStatus.

Enumerator:
LLVM_LTO_UNKNOWN 
LLVM_LTO_OPT_SUCCESS 
LLVM_LTO_READ_SUCCESS 
LLVM_LTO_READ_FAILURE 
LLVM_LTO_WRITE_FAILURE 
LLVM_LTO_NO_TARGET 
LLVM_LTO_NO_WORK 
LLVM_LTO_MODULE_MERGE_FAILURE 
LLVM_LTO_ASM_FAILURE 
LLVM_LTO_NULL_OBJECT 

Definition at line 35 of file LinkTimeOptimizer.h.


Function Documentation

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.
