C++ (Cpp) float64_to_float128 Examples

Example #1

File: fpu_helper.c Project: frenchleaf/qemu

/* convert 64-bit float to 128-bit float */
void HELPER(lxdbr)(CPUS390XState *env, uint32_t f1, uint32_t f2)
{
    CPU_QuadU res;

    res.q = float64_to_float128(env->fregs[f2].d, &env->fpu_status);
    env->fregs[f1].ll = res.ll.upper;
    env->fregs[f1 + 2].ll = res.ll.lower;
}

Example #2

File: fpu_helper.c Project: frenchleaf/qemu

/* load 128-bit FP zero */
void HELPER(lzxr)(CPUS390XState *env, uint32_t f1)
{
    CPU_QuadU x;

    x.q = float64_to_float128(float64_zero, &env->fpu_status);
    env->fregs[f1].ll = x.ll.upper;
    env->fregs[f1 + 1].ll = x.ll.lower;
}
