	* config/tc-mn10200.c (md_assemble): Likewise.
	* config/tc-moxie.c (md_assemble): Likewise.
	* config/tc-pj.c (md_apply_fix): Handle BFD_RELOC_PJ_CODE_REL32.
	* testsuite/gas/all/gas.exp (diff1 test): Alpha sort list of
	exception targets.  Add alpha, hppa, microblaze and rl78 to list
	of exceptions.
	(forward): Add microblaze to list of exceptions.
	(fwdexp): Add alpha to list of exceptions.
	(redef2): Add arm-epoc-pe and rl78 to list of exceptions.
	(redef3): Add rl78 and x86_64 cygwin to list of exceptions.
	(do_930509a): Alpha sort list of exception targets.  Add h8300 and
	mn10200 to list of exceptions.
	(align2): Expect to fail for nds32.
	(cond): Add alpha and rl78 to list of exceptions.
	* testsuite/gas/all/none.d: Skip for ft32 and hppa.
	* testsuite/gas/all/string.d: Skip for tic4x.
	* testsuite/gas/alpha/alpha.exp: Note that the alpha-linuxecoff
	target does not support ELF.
	* testsuite/gas/arm/blx-bl-convert.dL Skip for the nto target.
	* testsuite/gas/cfi/cfi-alpha-2.d: All extended format names.
	* testsuite/gas/cfi/cfi.exp: Alpha sort list of targets.  Skip SH
	tests for sh-pe and sh-rtemscoff targets.
	* testsuite/gas/elf/elf.exp (redef): Add rl78, xgate and vax to
	list of exceptions.
	(type): Run the noifunc version for alpha-freebsd and visium.
	* testsuite/gas/elf/warn-2.s: Do not expect to fail on the mcore,
	mn10200 or moxie targets.
	* testsuite/gas/ft32/insn.d: Update expected disassembly.
	* testsuite/gas/i386/i386.exp (x86-64-pcrel): Skip for cygwin
	targets.
	* testsuite/gas/lns/lns.exp (lns-common-1): No longer skip for
	mcore and rx targets.
	* testsuite/gas/macros/macros.exp (dot): Add exceptions for ns32k,
	rl78 and vax.
	(purge): Expect to fail on the ns32k and vax.
	* testsuite/gas/nds32/alu-2.d: Update expected disassembly.
	* testsuite/gas/nds32/ls.d: Likewise.
	* testsuite/gas/nds32/sys-reg.d: Likewise.
	* testsuite/gas/nds32/usr-spe-reg.d: Likewise.
	* testsuite/gas/pe/aligncomm-d.d: Skip for the sh.
	* testsuite/gas/pe/section-align-3.d: Likewise.
	* testsuite/gas/pe/section-exclude.d: Likewise.
	* testsuite/gas/ppc/test2xcoff32.d: Pass once all the required
	data has been seen.
	* testsuite/gas/ppc/textalign-xcoff-001.d: Fix up regexp to allow
	for variations in whitespace.
	* testsuite/gas/tilepro/t_constants.d: Pass once all the required
	data has been seen.
	* testsuite/gas/tilepro/t_constants.s (.safe_word): New macro.
	Installs a 32-bit value without generating warnings on 64-bit
	hosts.
	Use the new macro to replace the .word directives.

opcodes	* nds32-dis.c (nds32_parse_audio_ext): Change printing of integer
	constants to match expected behaviour.
	(nds32_parse_opcode): Likewise.  Also for whitespace.
