[amdgcn] Scale number of threads/workers with VGPR usage
2020-01-31 Kwok Cheung Yeung <kcy@codesourcery.com>
gcc/
* config/gcn/mkoffload.c (process_asm): Add sgpr_count and vgpr_count
to definition of hsa_kernel_description. Parse assembly to find SGPR
and VGPR count of kernel and store in hsa_kernel_description.
libgomp/
* plugin/plugin-gcn.c (struct hsa_kernel_description): Add sgpr_count
and vgpr_count fields.
(struct kernel_info): Add a field for a hsa_kernel_description.
(run_kernel): Reduce the number of threads/workers if the requested
number would require too many VGPRs.
(init_basic_kernel_info): Initialize description field with
the hsa_kernel_description entry for the kernel.
