From 7d88bd0b9c4ca12235769a04c45842dab3b54827 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20R=C3=B8nne=20Petersen?= Date: Tue, 30 Jul 2024 02:55:49 +0200 Subject: [PATCH] std.simd: Fix an isARM() check to use isArmOrThumb() instead. Thumb can have NEON instructions too. --- lib/std/simd.zig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/lib/std/simd.zig b/lib/std/simd.zig index a0f84b1a1d..236b9fbab8 100644 --- a/lib/std/simd.zig +++ b/lib/std/simd.zig @@ -18,7 +18,7 @@ pub fn suggestVectorLengthForCpu(comptime T: type, comptime cpu: std.Target.Cpu) if (std.Target.x86.featureSetHasAny(cpu.features, .{ .prefer_256_bit, .avx2 }) and !std.Target.x86.featureSetHas(cpu.features, .prefer_128_bit)) break :blk 256; if (std.Target.x86.featureSetHas(cpu.features, .sse)) break :blk 128; if (std.Target.x86.featureSetHasAny(cpu.features, .{ .mmx, .@"3dnow" })) break :blk 64; - } else if (cpu.arch.isARM()) { + } else if (cpu.arch.isArmOrThumb()) { if (std.Target.arm.featureSetHas(cpu.features, .neon)) break :blk 128; } else if (cpu.arch.isAARCH64()) { // SVE allows up to 2048 bits in the specification, as of 2022 the most powerful machine has implemented 512-bit
