Comment 9 for bug 1701835

The fpcr value seen in a process running in a VM comes from the Linux kernel, file linux/arch/alpha/kernel/process.c, function flush_thread():

        /* Arrange for each exec'ed process to start off with a clean slate
           with respect to the FPU. This is all exceptions disabled. */
        current_thread_info()->ieee_state = 0;
        wrfpcr(FPCR_DYN_NORMAL | ieee_swcr_to_fpcr(0));

where FPCR_DYN_NORMAL is 0x2UL << 58 /* towards nearest */

Where do we go from here? As far as I understand, qemu-alpha ought to initialize the DYN bits to FPCR_DYN_NORMAL. Where in the code should this be done? I see code in target/alpha/cpu.c, function alpha_cpu_initfn, that initializes the DYN bits to FPCR_DYN_NORMAL. Is this at the wrong place? Is it insufficient for another reason?
