pcpa d91b25d1be Implement the qmul and qdiv instructions. 
2013-02-04 Paulo Andrade <pcpa@gnu.org>

	* include/lightning.h, include/lightning/jit_private.h,
	lib/jit_arm-cpu.c, lib/jit_arm.c, lib/jit_mips-cpu.c,
	lib/jit_mips.c, lib/jit_ppc-cpu.c, lib/jit_ppc.c,
	lib/jit_x86-cpu.c, lib/jit_x86.c, lib/lightning.c:
	Implement the new qmul and qdiv instructions that return signed
	and unsigned lo/hi multiplication result and div/rem division result.
	These should be useful for jit translation of code that needs to
	know if a multiplication overflows (no branch opcode added) or if
	a division is exact (easy check if remainder is zero).

	* check/lightning.c, lib/jit_print.c, check/Makefile.am,
	check/all.tst: Update for the new qmul and qdiv instructions.

	* check/qalu.inc, check/qalu_div.ok, check/qalu_div.tst,
	check/qalu_mul.ok, check/qalu_mul.tst: New files implementing
	simple test cases for qmul and qdiv.

GNU lightning is a library to aid in making portable programs
that compile assembly code at run time.  For more information,
