@item TC_LINKRELAX_FIXUP ($var{segT})
@cindex TC_LINKRELAX_FIXUP
If defined, this macro allows control over whether fixups for a
given section will be processed when the @var{linkrelax} variable is
set. The macro is given the N_TYPE bits for the section in its
@var{segT} argument. If the macro evaluates to a non-zero value
then the fixups will be converted into relocs, otherwise they will
be passed to @var{md_apply_fix3} as normal.
