New Revision: 254012
URL: https://gcc.gnu.org/viewcvs?rev=254012&root=gcc&view=rev
Log:
* i386.c (dimode_scalar_chain::compute_convert_gain): Use
xmm_move instead of sse_move.
(sse_store_index): New function.
(ix86_register_move_cost): Be more sensible about mismatch stall;
model AVX moves correctly; make difference between sse->integer and
integer->sse.
(ix86_builtin_vectorization_cost): Model correctly aligned and unaligned
moves; make difference between SSE and AVX.
* i386.h (processor_costs): Remove sse_move; add xmm_move, ymm_move
and zmm_move. Increase size of sse load and store tables;
add unaligned load and store tables; add ssemmx_to_integer.
* x86-tune-costs.h: Update all entries according to real
move latencies from Agner Fog's manual and chip documentation.
