Ah, that's it then. I was curious to know why were the
upper parts of the ymm unavailable.
Are you hitting:
regcache_raw_read ()
{
...
/* A number of targets can't access the whole set of raw
registers (because the debug API provides no means to get at
them). */
if (regcache->register_status[regnum] == REG_UNKNOWN)
regcache->register_status[regnum] = REG_UNAVAILABLE;
}
?
