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. |
