Struct gimli::DebugLine
[−]
[src]
pub struct DebugLine<'input, Endian> where Endian: Endianity { /* fields omitted */ }
The DebugLine
struct contains the source location to instruction mapping
found in the .debug_line
section.
Methods
impl<'input, Endian> DebugLine<'input, Endian> where Endian: Endianity
[src]
fn new(debug_line_section: &'input [u8]) -> DebugLine<'input, Endian>
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::<LittleEndian>::new(read_debug_line_section_somehow());
fn header(&self,
offset: DebugLineOffset,
address_size: u8,
comp_dir: Option<&'input CStr>,
comp_name: Option<&'input CStr>)
-> Result<LineNumberProgramHeader<'input, Endian>>
offset: DebugLineOffset,
address_size: u8,
comp_dir: Option<&'input CStr>,
comp_name: Option<&'input CStr>)
-> Result<LineNumberProgramHeader<'input, Endian>>
Parse the line number program header 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, LineNumberProgramHeader, LittleEndian}; let debug_line = DebugLine::<LittleEndian>::new(read_debug_line_section_somehow()); // 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 header = debug_line.header(offset, address_size, None, None) .expect("should have found a header at that offset, and parsed it OK");
