Sigurd Schneider c875a64377 [turbofan] Reduce consecutive machine additions with constants ... This adds optimizations that apply the reductions (x + Int32Constant(a)) + Int32Constant(b)) => x + Int32Constant(a + b) (x + Int64Constant(a)) + Int64Constant(b)) => x + Int64Constant(a + b) to the TurboFan graph. This helps reducing awkward sequences like leaq r12,[r9*8+0x8] movq r12,[rbx+r12*1-0x1] to movq r12,[rax+r9*8+0x7] Change-Id: Iaa3a1cb9136a3f905ba33c62e16c3cb3c117605c Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1627544 Auto-Submit: Sigurd Schneider <sigurds@chromium.org> Reviewed-by: Benedikt Meurer <bmeurer@chromium.org> Reviewed-by: Jaroslav Sevcik <jarin@chromium.org> Commit-Queue: Sigurd Schneider <sigurds@chromium.org> Cr-Commit-Position: refs/heads/master@{#61817}		2019-05-24 08:45:59 +00:00
