Methods
¶DIEDwarfExpression(const llvm::AsmPrinter& AP,
llvm::DwarfCompileUnit& CU,
llvm::DIELoc& DIE)
DIEDwarfExpression(const llvm::AsmPrinter& AP,
llvm::DwarfCompileUnit& CU,
llvm::DIELoc& DIE)Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:430
Parameters
- const llvm::AsmPrinter& AP
- llvm::DwarfCompileUnit& CU
- llvm::DIELoc& DIE
¶void commitTemporaryBuffer()
void commitTemporaryBuffer()Description
Commit the data stored in the temporary buffer to the main output.
Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:424
¶void disableTemporaryBuffer()
void disableTemporaryBuffer()Description
Disable emission to the temporary buffer. This does not commit data in the temporary buffer to the main output.
Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:422
¶void emitBaseTypeRef(uint64_t Idx)
void emitBaseTypeRef(uint64_t Idx)Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:419
Parameters
- uint64_t Idx
¶void emitData1(uint8_t Value)
void emitData1(uint8_t Value)Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:418
Parameters
- uint8_t Value
¶void emitOp(uint8_t Op,
const char* Comment = nullptr)
void emitOp(uint8_t Op,
const char* Comment = nullptr)Description
Output a dwarf operand and an optional assembler comment.
Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:415
Parameters
- uint8_t Op
- const char* Comment = nullptr
¶void emitSigned(int64_t Value)
void emitSigned(int64_t Value)Description
Emit a raw signed value.
Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:416
Parameters
- int64_t Value
¶void emitUnsigned(uint64_t Value)
void emitUnsigned(uint64_t Value)Description
Emit a raw unsigned value.
Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:417
Parameters
- uint64_t Value
¶void enableTemporaryBuffer()
void enableTemporaryBuffer()Description
Start emitting data to the temporary buffer. The data stored in the temporary buffer can be committed to the main output using commitTemporaryBuffer().
Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:421
¶llvm::DIELoc* finalize()
llvm::DIELoc* finalize()Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:432

llvm::DIELoc& getActiveDIE()Description
Return the DIE that currently is being emitted to.
Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:413
¶unsigned int getTemporaryBufferSize()
unsigned int getTemporaryBufferSize()Description
Return the emitted size, in number of bytes, for the data stored in the temporary buffer.
Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:423
¶bool isFrameRegister(
const llvm::TargetRegisterInfo& TRI,
llvm::Register MachineReg)
bool isFrameRegister(
const llvm::TargetRegisterInfo& TRI,
llvm::Register MachineReg)Description
Return whether the given machine register is the frame register in the current function.
Declared at: llvm/lib/CodeGen/AsmPrinter/DwarfExpression.h:426
Parameters
- const llvm::TargetRegisterInfo& TRI
- llvm::Register MachineReg
