class CFIProgram

Declaration

class CFIProgram { /* full declaration omitted */ };

Description

Represent a sequence of Call Frame Information instructions that, when read in order, construct a table mapping PC to frame state. This can also be referred to as "CFI rules" in DWARF literature to avoid confusion with computer programs in the broader sense, and in this context each instruction would be a rule to establish the mapping. Refer to pg. 172 in the DWARF5 manual, "6.4.1 Structure of Call Frame Information".

          bool IsEH,
          unsigned int IndentLevel = 1) const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugFrame.h:74

Parameters

llvm::raw_ostream& OS

const llvm::MCRegisterInfo* MRI

bool IsEH

unsigned int IndentLevel = 1

¶bool empty() const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugFrame.h:60

¶llvm::dwarf::CFIProgram::iterator end()

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugFrame.h:56

¶llvm::dwarf::CFIProgram::const_iterator end()
    const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugFrame.h:57

¶llvm::Error parse(llvm::DWARFDataExtractor Data,
                  uint64_t* Offset,
                  uint64_t EndOffset)

Description

Parse and store a sequence of CFI instructions from Data, starting at *Offset and ending at EndOffset. *Offset is updated to EndOffset upon successful parsing, or indicates the offset where a problem occurred in case an error is returned.

Parameters

llvm::DWARFDataExtractor Data

uint64_t* Offset

uint64_t EndOffset
