[Mesa-dev] [PATCH 00/13] i965: Make LOAD_PAYLOAD sane again

[Jason Ekstrand]

This patch series comes with two apologies.  First, is for the fact that
most of it has to be squashed into a single super-commit.  Unfortunately,
this is one of those things that can't really be done incrementally.
Second, is for the absolute disaster that I left LOAD_PAYLOAD in at the end
of my send-from-GRF series.  That was the first time I had ever touched the
compiler and I didn't know what I was doing.

This series makes LOAD_PAYLOAD far more sane.  For details on how the new
LOAD_PAYLOAD works, see patch 09/13.  Also, It's less code. :-)

Jason Ekstrand (13):
  i965/fs_cse: Factor out code to create copy instructions
  i965: Change header_present to header_size in backend_instruction
  i965/register_coalesce: Do register size checks before is_copy_payload
  i965/fs_inst: Add an is_copy_payload helper
  i965/fs: Make emit_single_fb_write take an explicit exec_size
  i965/fs: Make LOAD_PAYLOAD take a header size
  i965/fs: Rework fs_visitor::LOAD_PAYLOAD
  SQUASH: i965/fs: Make destinations of load_payload have the
    appropreate width
  SQUASH: i965/fs: Rework fs_visitor::lower_load_payload
  SQUASH: i965/fs_cse: Support the new-style LOAD_PAYLOAD
  SQUASH: i965/fs_inst::is_copy_payload: Support the new-style
