Methods

¶DWARFAddressRange()

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFAddressRange.h:30

¶DWARFAddressRange(
    uint64_t LowPC,
    uint64_t HighPC,
    uint64_t SectionIndex =
        object::SectionedAddress::UndefSection)

Description

Used for unit testing.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFAddressRange.h:33

Parameters

uint64_t LowPC

uint64_t HighPC

uint64_t SectionIndex = object::SectionedAddress::UndefSection

¶void dump(
    llvm::raw_ostream& OS,
    uint32_t AddressSize,
    llvm::DIDumpOptions DumpOpts = {},
    const llvm::DWARFObject* Obj = nullptr) const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFAddressRange.h:71

Parameters

llvm::raw_ostream& OS

uint32_t AddressSize

llvm::DIDumpOptions DumpOpts = {}

const llvm::DWARFObject* Obj = nullptr

¶bool intersects(
    const llvm::DWARFAddressRange& RHS) const

Description

Returns true if [LowPC, HighPC) intersects with [RHS.LowPC, RHS.HighPC).

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFAddressRange.h:43

Parameters

const llvm::DWARFAddressRange& RHS

¶bool merge(const llvm::DWARFAddressRange& RHS)

Description

Union two address ranges if they intersect. This function will union two address ranges if they intersect by modifying this range to be the union of both ranges. If the two ranges don't intersect this range will be left alone.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFAddressRange.h:63

Parameters

const llvm::DWARFAddressRange& RHS

Another address range to combine with.

Returns

false if the ranges don't intersect, true if they do and the ranges were combined.

¶bool valid() const

Description

Returns true if LowPC is smaller or equal to HighPC. This accounts for dead-stripped ranges.
