With Broadwell we have the option to run vertex shaders in scalar (SIMD8)
mode which potentially gives us better throughput and more vertices
per thread dispatch. This patch series implements this by repurposing our
fs backend to also work for vertex shaders.
Kristian Høgsberg (14):
i965: Don't copy propagate sat MOVs into LOAD_PAYLOAD
i965: Generalize fs_generator further
i965: Set shader name for generator from call site
i965: Remove shader program argument and member from fs_generator
i965: Add SIMD8 URB write low-level IR instruction
i965: Add new SIMD8 VS prog data flag
i965: Consolidate code to get struct brw_sampler_prog_key_data
i965: Prepare for using the ATTR register file in the fs backend
i965: Move more code into codegen-branch of the fs_visitor::run() if
statement
i965: Move fs_visitor optimization pass into new method
fs_visitor::optimize()
i965: Move fs_visitor ra pass to new fs_visitor::allocate_registers()
i965: Add fs_visitor::run_vs() to generate scalar vertex shader code
i965: Clean up fs_visitor::run and rename to run_fs
i965: Generate vs code using scalar backend for BDW+
