gcc/
* config/gcn/gcn.c (default_requested_args): New.
(gcn_parse_amdgpu_hsa_kernel_attribute): Initialize requested args
set with default_requested_args.
(gcn_conditional_register_usage): Limit register usage of non-kernel
functions. Reassign fixed registers if a non-standard set of args is
requested.
* config/gcn/gcn.h (FIXED_REGISTERS): Fix registers according to ABI.
