Function locate_debugaltlink
pub(in ::backtrace_rs::symbolize::gimli::elf) fn locate_debugaltlink(path: &Path, filename: &OsStr, build_id: &[u8]) -> Option<PathBuf>Locate a file specified in a .gnu_debugaltlink section.
path is the file containing the section.
filename and build_id are the contents of the section.
Search order is based on gdb:
- filename, which is either absolute or relative to
path - the build ID path under
BUILD_ID_PATH
gdb also allows the user to customize the debug search path, but we don't.
gdb also supports debuginfod, but we don't yet.
