From 45ce540b9b756f372840e923b73cfd7e3edd85f8 Mon Sep 17 00:00:00 2001 From: Wunk Date: Sun, 2 Oct 2022 02:17:19 -0700 Subject: ARMeilleure: Add `gfni` acceleration (#3669) * ARMeilleure: Add `GFNI` detection This is intended for utilizing the `gf2p8affineqb` instruction * ARMeilleure: Add `gf2p8affineqb` Not using the VEX or EVEX-form of this instruction is intentional. There are `GFNI`-chips that do not support AVX(so no VEX encoding) such as Tremont(Lakefield) chips as well as Jasper Lake. https://github.com/InstLatx64/InstLatx64/blob/13df339fe7150b114929f71b19a6b2fe72fc751e/GenuineIntel/GenuineIntel00806A1_Lakefield_LC_InstLatX64.txt#L1297-L1299 https://github.com/InstLatx64/InstLatx64/blob/13df339fe7150b114929f71b19a6b2fe72fc751e/GenuineIntel/GenuineIntel00906C0_JasperLake_InstLatX64.txt#L1252-L1254 * ARMeilleure: Add `gfni` acceleration of `Rbit_V` Passes all `Rbit_V*` unit tests on my `i9-11900k` * ARMeilleure: Add `gfni` acceleration of `S{l,r}i_V` Also added a fast-path for when the shift amount is greater than the size of the element. * ARMeilleure: Add `gfni` acceleration of `Shl_V` and `Sshr_V` * ARMeilleure: Increment InternalVersion * ARMeilleure: Fix Intrinsic and Assembler Table alignment `gf2p8affineqb` is the longest instruction name I know of. It shouldn't get any wider than this. * ARMeilleure: Remove SSE2+SHA requirement for GFNI * ARMeilleure Add `X86GetGf2p8LogicalShiftLeft` Used to generate GF(2^8) 8x8 bit-matrices for bit-shifting for the `gf2p8affineqb` instruction. * ARMeilleure: Append `FeatureInfo7Ecx` to `FeatureInfo` --- ARMeilleure/IntermediateRepresentation/Intrinsic.cs | 1 + 1 file changed, 1 insertion(+) (limited to 'ARMeilleure/IntermediateRepresentation') diff --git a/ARMeilleure/IntermediateRepresentation/Intrinsic.cs b/ARMeilleure/IntermediateRepresentation/Intrinsic.cs index 71bfc3be..bc1285be 100644 --- a/ARMeilleure/IntermediateRepresentation/Intrinsic.cs +++ b/ARMeilleure/IntermediateRepresentation/Intrinsic.cs @@ -47,6 +47,7 @@ namespace ARMeilleure.IntermediateRepresentation X86Divps, X86Divsd, X86Divss, + X86Gf2p8affineqb, X86Haddpd, X86Haddps, X86Insertps, -- cgit v1.2.3
