From d5ab5485430c00734a79068fe0eee7bd4f87cf00 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20Gustavsson?= Date: Thu, 9 Dec 2010 21:31:08 +0100 Subject: Eliminate the specific move_sd instruction The move_sd specific instruction is no longer used since there are specific move instructions covering all possible permutations of operands. Also eliminate the move_cy instruction because it is almost never generated by the compiler. --- erts/emulator/beam/ops.tab | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'erts/emulator/beam/ops.tab') diff --git a/erts/emulator/beam/ops.tab b/erts/emulator/beam/ops.tab index c10b3e8d52..0b2e2dca83 100644 --- a/erts/emulator/beam/ops.tab +++ b/erts/emulator/beam/ops.tab @@ -279,6 +279,11 @@ move2 x y x y move2 y x y x move2 x x x x +# The compiler almost never generates a "move Literal y(Y)" instruction, +# so let's cheat if we encounter one. +move S=n D=y => init D +move S=c D=y => move S x | move x D + %macro:move Move -pack -gen_dest move x x move x y @@ -289,15 +294,10 @@ move r x move r y move c r move c x -move c y move n x move n r move y y -%cold -move s d -%hot - # Receive operations. loop_rec Fail Src | smp_mark_target_label(Fail) => i_loop_rec Fail Src -- cgit v1.2.3
