field.

(set_at, load_register, macro): Changed calls to macro_build to
pass new argument for i, j and o cases.

names for 'E' and 'G' argument types (coprocessor registers) and
don't warn if $1 is used on the coprocessor.

poc_handler field.
* configure.in (case ${generic_target}): Add i[34]86-*-sysv4*
case to set obj_format=elf. Must go before i386-*-sysv* case that
sets obj_format=coffbsd. Add *-*-sysv4* to *-*-elf and
*-*-solaris case, and move to before *-sysv* case that wants to
set obj_format to coff.

'exp->X_op'.

instead.

Define.
* config/obj-elf.c (obj_elf_stab_generic): Check expression
segment rather than sy_forward.
