◆ DumpAPInt()

static lldb::offset_t DumpAPInt ( Stream s,
const DataExtractor data,
lldb::offset_t  offset,
lldb::offset_t  byte_size,
bool  is_signed,
unsigned  radix 

◆ DumpCharacter()

static void DumpCharacter ( Stream s,
const char  c 

Dump the character to a stream.

A character that is not printable will be represented by its escape sequence.

◆ DumpFloatingPoint()

template<typename FloatT >
void DumpFloatingPoint ( std::ostringstream &  ss,
FloatT  f 

Dump a floating point type.

offset_t  start_offset,
uint64_t  base_addr,
size_t  number_of_instructions 

◆ GetAPInt()

static llvm::Optional<llvm::APInt> GetAPInt ( const DataExtractor data,
lldb::offset_t offset_ptr,
lldb::offset_t  byte_size 

◆ GetFloatSemantics()

◆ GetMemoryTags()

static llvm::Optional<MemoryTagMap> GetMemoryTags ( lldb::addr_t  addr,
size_t  length,
ExecutionContextScope exe_scope 

◆ printMemoryTags()

static void printMemoryTags ( const DataExtractor DE,
Stream s,
lldb::addr_t  addr,
size_t  len,
const llvm::Optional< MemoryTagMap > &  memory_tag_map 

◆ TryDumpSpecialEscapedChar()

static bool TryDumpSpecialEscapedChar ( Stream s,
const char  c 

Prints the specific escape sequence of the given character to the stream.

If the character doesn't have a known specific escape sequence (e.g., '', '
' but not generic escape sequences such as'\x12'), this function will not modify the stream and return false.
