@ -203,6 +203,12 @@ Used with a register branch format instruction (e.g.@: @code{jsr}) to
indicate that the literal is used for a call. During relaxation, the
code may be altered to use a direct branch (e.g.@: @code{bsr}).
@item !lituse_jsrdirect!@var{N}
Similar to @code{lituse_jsr}, but also that this call cannot be vectored
through a PLT entry. This is useful for functions with special calling
conventions which do not allow the normal call-clobbered registers to be
clobbered.
@item !lituse_bytoff!@var{N}
Used with a byte mask instruction (e.g.@: @code{extbl}) to indicate
that only the low 3 bits of the address are relevant. During relaxation,
