tint/hlsl: remove [loop] attribute on all loops I added the forcing of the "loop" attribute to all loops to address FXC failing on uniformity errors related to gradients in loops. Since then, Tint now implements UA and it recently became an error, so we no longer need this hack. As a result, FXC is now better able to cope with loops that it determines executes 0 times. Most e2e tests are affected because so many use loops, but 27 tests that were previously failing are now passing with this change: tint/bug/tint/1538.wgsl.expected.fxc.hlsl tint/bug/tint/1604.wgsl.expected.fxc.hlsl tint/bug/tint/1605.wgsl.expected.fxc.hlsl tint/unittest/reader/spirv/SpvParserCFGTest_ClassifyCFGEdges_LoopBreak_FromLoopHeader_SingleBlockLoop_TrueBranch.spvasm.expected.fxc.hlsl tint/unittest/reader/spirv/SpvParserCFGTest_ComputeBlockOrder_Loop_HeaderHasBreakUnless.spvasm.expected.fxc.hlsl tint/unittest/reader/spirv/SpvParserCFGTest_EmitBody_IfSelection_TrueBranch_LoopBreak.spvasm.expected.fxc.hlsl tint/unittest/reader/spirv/SpvParserCFGTest_FindIfSelectionInternalHeaders_TrueBranch_LoopBreak_Ok.spvasm.expected.fxc.hlsl tint/unittest/reader/spirv/SpvParserFunctionVarTest_EmitStatement_Phi_MultiBlockLoopIndex.spvasm.expected.fxc.hlsl tint/unittest/reader/spirv/SpvParserFunctionVarTest_EmitStatement_Phi_SingleBlockLoopIndex.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/cov-dead-code-unreachable-merge/0-opt.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/cov-dead-code-unreachable-merge/0-opt.wgsl.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/similar-nested-ifs/0-opt.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/similar-nested-ifs/0-opt.wgsl.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/spv-load-from-frag-color/1.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/spv-load-from-frag-color/1.wgsl.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-false-if-discard-loop/0.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-false-if-discard-loop/0.wgsl.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-fragcoord-less-than-zero/0.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-fragcoord-less-than-zero/0.wgsl.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-fragcoord-less-than-zero/1.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-fragcoord-less-than-zero/1.wgsl.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-with-loop-read-write-global/0-opt.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-with-loop-read-write-global/0-opt.wgsl.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-with-loop-read-write-global/1.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/stable-binarysearch-tree-with-loop-read-write-global/1.wgsl.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/write-red-after-search/0-opt.spvasm.expected.fxc.hlsl tint/vk-gl-cts/graphicsfuzz/write-red-after-search/0-opt.wgsl.expected.fxc.hlsl Bug: tint:1522 Bug: tint:1538 Bug: tint:1604 Bug: tint:1605 Change-Id: I530b846b6b8df122ab351ff7b85d3e1c9ac11526 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/104121 Reviewed-by: Ben Clayton <bclayton@google.com> Commit-Queue: Antonio Maiorano <amaiorano@google.com> Kokoro: Kokoro <noreply+kokoro@google.com>
