Frame data for a code block.

Fields

ty: FrameType

Compiler-specific frame type.

code_start: PdbInternalRva

Relative virtual address of the start of the code block.

Note that this address is internal to the PDB. To convert this to an actual Rva, use PdbInternalRva::to_rva.

code_size: u32

Size of the code block covered by this frame data in bytes.

locals_size: u32

Size of local variables pushed on the stack in bytes.

params_size: u32

Size of parameters pushed on the stack in bytes.

prolog_size: u16

Number of bytes of prologue code in the block.

saved_regs_size: u16

Size of saved registers pushed on the stack in bytes.

max_stack_size: Option<u32>

The maximum number of bytes pushed on the stack.

has_structured_eh: bool

Indicates that structured exception handling is in effect.

has_cpp_eh: bool

Indicates that C++ exception handling is in effect.

is_function_start: bool

Indicates that this frame is the start of a function.

uses_base_pointer: bool

Indicates that this function uses the EBP register.

program: Option<StringRef>

A program string allowing to reconstruct register values for this frame.

The program string is a sequence of macros that is interpreted in order to establish the prologue. For example, a typical stack frame might use the program string "$T0 $ebp = $eip $T0 4 + ^ = $ebp $T0 ^ = $esp $T0 8 + =". The format is reverse polish notation, where the operators follow the operands. T0 represents a temporary variable on the stack.

Note that the program string is specific to the CPU and to the calling convention set up for the function represented by the current stack frame.

Trait Implementations

impl Clone for FrameData

fn clone(&self) -> FrameData

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FrameData

fn fmt(&self, f: &mut Formatter<'_>) -> Result
