/* The LTO representations for the bodies of functions may refer to
the LTO representations of global functions, variables, and
types.
Because LTO operates on relocatable object files, using an ordinary
label would require that the link-time optimizer perform much of
the relocation processing normally performed by a linker.
Therefore, the references used are pairs of the form (SECTION,
OFFSET).
The functions below indicate the OFFSET by using two labels. The
caller is responsible for emitting the offset as the difference
between these two labels. The labels are guaranteed to be in the
same section. The functions lto_{type,var,fn}_ref in the LTO front
end are used to resolve these references in the LTO front end. */
