Function Documentation

decode()

static llvm::Expected<InlineInfo> decode ( DataExtractor &  Data, uint64_t &  Offset, uint64_t  BaseAddr  )

static

Decode an InlineInfo in Data at the specified offset.

A local helper function to decode InlineInfo objects. This function is called recursively when parsing child InlineInfo objects.

Parameters

Data	The data extractor to decode from.
Offset	The offset within Data to decode from.
BaseAddr	The base address to use when decoding address ranges.

Returns

An InlineInfo or an error describing the issue that was encountered during decoding.

lookup()

static bool lookup ( const GsymReader &  GR, DataExtractor &  Data, uint64_t &  Offset, uint64_t  BaseAddr, uint64_t  Addr, SourceLocations &  SrcLocs, llvm::Error &  Err  )

static

A Lookup helper functions.

Used during the InlineInfo::lookup() call to quickly only parse an InlineInfo object if the address falls within this object. This avoids allocations by not appending child InlineInfo objects to the InlineInfo::Children array and also skips any InlineInfo objects that do not contain the address we are looking up.

Parameters

Data	The binary stream to read the data from.
Offset	The byte offset within Data.
BaseAddr	The address that the relative address range offsets are relative to.

skip()

static bool skip ( DataExtractor &  Data, uint64_t &  Offset, bool  SkippedRanges  )

static

Skip an InlineInfo object in the specified data at the specified offset.

Used during the InlineInfo::lookup() call to quickly skip child InlineInfo objects where the addres ranges isn't contained in the InlineInfo object or its children. This avoids allocations by not appending child InlineInfo objects to the InlineInfo::Children array.

Parameters

Data	The binary stream to read the data from.
Offset	The byte offset within Data.
SkippedRanges	If true, address ranges have already been skipped.
