Enum rustc_session::config::SplitDwarfKind
source · pub enum SplitDwarfKind {
Single,
Split,
}
Expand description
Split debug-information is enabled by -C split-debuginfo
, this enum is only used if split
debug-information is enabled (in either Packed
or Unpacked
modes), and the platform
uses DWARF for debug-information.
Some debug-information requires link-time relocation and some does not. LLVM can partition the debuginfo into sections depending on whether or not it requires link-time relocation. Split DWARF provides a mechanism which allows the linker to skip the sections which don’t require link-time relocation - either by putting those sections in DWARF object files, or by keeping them in the object file in such a way that the linker will skip them.
Variants§
Single
Sections which do not require relocation are written into object file but ignored by the linker.
Split
Sections which do not require relocation are written into a DWARF object (.dwo
) file
which is ignored by the linker.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
