Struct gimli::DebugLine [−][src]
pub struct DebugLine<R: Reader> { /* fields omitted */ }
The DebugLine
struct contains the source location to instruction mapping
found in the .debug_line
section.
Methods
impl<'input, Endian> DebugLine<EndianSlice<'input, Endian>> where
Endian: Endianity,
[src]
impl<'input, Endian> DebugLine<EndianSlice<'input, Endian>> where
Endian: Endianity,
pub fn new(debug_line_section: &'input [u8], endian: Endian) -> Self
[src]
pub fn new(debug_line_section: &'input [u8], endian: Endian) -> Self
Construct a new DebugLine
instance from the data in the .debug_line
section.
It is the caller's responsibility to read the .debug_line
section and
present it as a &[u8]
slice. That means using some ELF loader on
Linux, a Mach-O loader on OSX, etc.
use gimli::{DebugLine, LittleEndian}; let debug_line = DebugLine::new(read_debug_line_section_somehow(), LittleEndian);

pub fn program(
&self,
offset: DebugLineOffset<R::Offset>,
address_size: u8,
comp_dir: Option<R>,
comp_name: Option<R>
) -> Result<IncompleteLineNumberProgram<R>>
[src]
pub fn program(
&self,
offset: DebugLineOffset<R::Offset>,
address_size: u8,
comp_dir: Option<R>,
comp_name: Option<R>
) -> Result<IncompleteLineNumberProgram<R>>
Parse the line number program whose header is at the given offset
in the
.debug_line
section.
The address_size
must match the compilation unit that the lines apply to.
The comp_dir
should be from the DW_AT_comp_dir
attribute of the compilation
unit. The comp_name
should be from the DW_AT_name
attribute of the
compilation unit.
use gimli::{DebugLine, DebugLineOffset, IncompleteLineNumberProgram, EndianSlice, LittleEndian}; let debug_line = DebugLine::new(read_debug_line_section_somehow(), LittleEndian); // In a real example, we'd grab the offset via a compilation unit // entry's `DW_AT_stmt_list` attribute, and the address size from that // unit directly. let offset = DebugLineOffset(0); let address_size = 8; let program = debug_line.program(offset, address_size, None, None) .expect("should have found a header at that offset, and parsed it OK");
