Typedef Documentation
◆ LLVMDisasmContextRef
| typedef void* LLVMDisasmContextRef |
An opaque reference to a disassembler context.
Definition at line 29 of file DisassemblerTypes.h.
◆ LLVMOpInfoCallback
| typedef int(* LLVMOpInfoCallback) (void *DisInfo, uint64_t PC, uint64_t Offset, uint64_t OpSize, uint64_t InstSize, int TagType, void *TagBuf) |
The type for the operand information call back function. This is called to get the symbolic information for an operand of an instruction. Typically this is from the relocation information, symbol table, etc. That block of information is saved when the disassembler context is created and passed to the call back in the DisInfo parameter. The instruction containing operand is at the PC parameter. For some instruction sets, there can be more than one operand with symbolic information. To determine the symbolic operand information for each operand, the bytes for the specific operand in the instruction are specified by the Offset parameter and its byte widith is the OpSize parameter. For instructions sets with fixed widths and one symbolic operand per instruction, the Offset parameter will be zero and InstSize parameter will be the instruction width. The information is returned in TagBuf and is Triple specific with its specific information defined by the value of TagType for that Triple. If symbolic information is returned the function * returns 1, otherwise it returns 0.
Definition at line 48 of file DisassemblerTypes.h.
◆ LLVMSymbolLookupCallback
| typedef const char *(* LLVMSymbolLookupCallback) (void *DisInfo, uint64_t ReferenceValue, uint64_t *ReferenceType, uint64_t ReferencePC, const char **ReferenceName) |
The type for the symbol lookup function. This may be called by the disassembler for things like adding a comment for a PC plus a constant offset load instruction to use a symbol name instead of a load address value. It is passed the block information is saved when the disassembler context is created and the ReferenceValue to look up as a symbol. If no symbol is found for the ReferenceValue NULL is returned. The ReferenceType of the instruction is passed indirectly as is the PC of the instruction in ReferencePC. If the output reference can be determined its type is returned indirectly in ReferenceType along with ReferenceName if any, or that is set to NULL.

Function Documentation
◆ LLVMCreateDisasm()
| LLVM_C_EXTERN_C_BEGIN 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.
◆ 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.
◆ 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.
◆ LLVMSetDisasmOptions()
| int LLVMSetDisasmOptions | ( | LLVMDisasmContextRef | DC, |
| uint64_t | Options | ||
| ) |
Set the disassembler's options. Returns 1 if it can set the Options and 0 otherwise.
