(gdb) p x_rtl.drap_reg
$1 = (rtx) 0x0
so
7843 /* Only need to push parameter pointer reg if it is caller saved.
*/
7844 if (!call_used_regs[REGNO (crtl->drap_reg)])
7845 {
segfaults. This must be really a latent issue. I guess
/* Conversion means we may have 128bit register spills/fills
which require aligned stack. */
if (converted_insns)
{
if (crtl->stack_alignment_needed < 128)
...
needs to do some magic for -mforce-drap (which might be handled too early,
ignoring the late generated xmm uses?)
