◆ LLVMCreateDisasm()

LLVMDisasmContextRef LLVMCreateDisasm ( const char TripleName,
void *  DisInfo,
int  TagType,
LLVMOpInfoCallback  GetOpInfo,
LLVMSymbolLookupCallback  SymbolLookUp 
)

Create a disassembler for the TripleName.

Symbolic disassembly is supported by passing a block of information in the DisInfo parameter and specifying the TagType and callback functions as described above. These can all be passed as NULL. If successful, this returns a disassembler context. If not, it returns NULL. This function is equivalent to calling LLVMCreateDisasmCPUFeatures() with an empty CPU name and feature set.

Definition at line 118 of file Disassembler.cpp.

References LLVMCreateDisasmCPUFeatures().

◆ LLVMCreateDisasmCPU()

LLVMDisasmContextRef LLVMCreateDisasmCPU ( const char Triple,
const char CPU,
void *  DisInfo,
int  TagType,
LLVMOpInfoCallback  GetOpInfo,
LLVMSymbolLookupCallback  SymbolLookUp 
)

Create a disassembler for the TripleName and a specific CPU.

Symbolic disassembly is supported by passing a block of information in the DisInfo parameter and specifying the TagType and callback functions as described above. These can all be passed * as NULL. If successful, this returns a disassembler context. If not, it returns NULL. This function is equivalent to calling LLVMCreateDisasmCPUFeatures() with an empty feature set.

◆ LLVMCreateDisasmCPUFeatures()

LLVMDisasmContextRef LLVMCreateDisasmCPUFeatures ( const char Triple,
const char CPU,
const char Features,
void *  DisInfo,
int  TagType,
LLVMOpInfoCallback  GetOpInfo,
LLVMSymbolLookupCallback  SymbolLookUp 
)

Create a disassembler for the TripleName, a specific CPU and specific feature string.

Symbolic disassembly is supported by passing a block of information in the DisInfo parameter and specifying the TagType and callback functions as described above. These can all be passed * as NULL. If successful, this returns a disassembler context. If not, it returns NULL.

◆ LLVMDisasmDispose()

void LLVMDisasmDispose ( LLVMDisasmContextRef  DC)

Dispose of a disassembler context.

References DC.

◆ LLVMDisasmInstruction()

size_t LLVMDisasmInstruction ( LLVMDisasmContextRef  DC,
uint8_t *  Bytes,
uint64_t  BytesSize,
uint64_t  PC,
char OutString,
size_t  OutStringSize 
)

Disassemble a single instruction using the disassembler context specified in the parameter DC.

The bytes of the instruction are specified in the parameter Bytes, and contains at least BytesSize number of bytes. The instruction is at the address specified by the PC parameter. If a valid instruction can be disassembled, its string is returned indirectly in OutString whose size is specified in the parameter OutStringSize. This function returns the number of bytes in the instruction or zero if there was no valid instruction.
