amdgcn: Work around XNACK register allocation problem
The extra register pressure is causing infinite loops in some cases, especially
at -O0. I have not yet observed any issue on devices that have AVGPRs for
spilling, and XNACK is only really useful on those devices anyway, so change
the defaults.
gcc/ChangeLog:
* config/gcn/gcn-hsa.h (NO_XNACK): Change the defaults.
* config/gcn/gcn-opts.h (enum hsaco_attr_type): Add HSACO_ATTR_DEFAULT.
* config/gcn/gcn.cc (gcn_option_override): Set the default flag_xnack.
* config/gcn/gcn.opt: Add -mxnack=default.
* doc/invoke.texi: Document the -mxnack default.
