	* config/tc-mips.c (CPU_HAS_MIPS16): Add mips-lsi-elf as MIPS16
	capable configuration.
	(macro_build): Check for MIPS16 capability, not for actual MIPS16 code
	generation.
	(mips_ip): Likewise.

	/gas/testsuite/ChangeLog
	* gas/mips/mips-jalx.d: New file, check jalx assembly.
	* gas/mips/mips-jalx.s: Likewise.
	* gas/mips/mips-no-jalx.l: Likewise.

	* gas/mips/mips16-jalx.d: Likewise.
	* gas/mips/mips16-jalx.s: Likewise.
	* gas/mips/mips.exp: Add new tests.

	/opcodes/ChangeLog:
	* mips-dis.c (print_insn_mips): Always allow disassembly of
	32-bit jalx opcode.
