<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-backend-amdgpu Author: Matt Arsenault (arsenm) <details> <summary>Changes</summary> Test other splitting situations that appear in greedy. This includes ensuring we have a case that hits a local split and instruction split (most of the tests hit the region split path). Also test a few cases where the final result isn't fully used, resulting in partial copy bundles instead of a simple full copy. Test physreg and virtreg agpr interference with a reassignment candidate. --- Patch is 80.77 KiB, truncated to 20.00 KiB below, full version: https://github.com/llvm/llvm-project/pull/149026.diff 2 Files Affected: - (modified) llvm/test/CodeGen/AMDGPU/inflate-reg-class-vgpr-mfma-to-agpr-negative-tests.mir (+437) - (modified) llvm/test/CodeGen/AMDGPU/inflate-reg-class-vgpr-mfma-to-av-with-load-source.mir (+267-137) ``````````diff diff --git a/llvm/test/CodeGen/AMDGPU/inflate-reg-class-vgpr-mfma-to-agpr-negative-tests.mir b/llvm/test/CodeGen/AMDGPU/inflate-reg-class-vgpr-mfma-to-agpr-negative-tests.mir index cd10fbb6020b8..482846e7a9313 100644 --- a/llvm/test/CodeGen/AMDGPU/inflate-reg-class-vgpr-mfma-to-agpr-negative-tests.mir +++ b/llvm/test/CodeGen/AMDGPU/inflate-reg-class-vgpr-mfma-to-agpr-negative-tests.mir @@ -20,7 +20,24 @@ ret void } + define amdgpu_kernel void @inflate_result_to_agpr__V_MFMA_F32_32X32X8F16_vgprcd_e64_chain_no_agprs_first() #1 { + ret void + } + + define amdgpu_kernel void @inflate_result_to_agpr__V_MFMA_F32_32X32X8F16_vgprcd_e64_chain_no_agprs_second() #1 { + ret void + } + + define amdgpu_kernel void @inflate_result_to_agpr__V_MFMA_F32_32X32X8F16_vgprcd_e64_chain_no_agprs_first_physreg() #1 { + ret void + } + + define amdgpu_kernel void @inflate_result_to_agpr__V_MFMA_F32_32X32X8F16_vgprcd_e64_chain_no_agprs_second_physreg() #1 { + ret void + } + attributes #0 = { "amdgpu-wave-limiter"="true" "amdgpu-waves-per-eu"="8,8" } + attributes #1 = { "amdgpu-wave-limiter"="true" "amdgpu-waves-per-eu"="10,10" } ... # Inflate pattern, except the defining instruction isn't an MFMA. @@ -393,3 +410,423 @@ body: | S_ENDPGM 0 ... + +# There isn't an assignable AGPR around the first MFMA. +--- +name: inflate_result_to_agpr__V_MFMA_F32_32X32X8F16_vgprcd_e64_chain_no_agprs_first +tracksRegLiveness: true +machineFunctionInfo: + isEntryFunction: true + stackPtrOffsetReg: '$sgpr32' + occupancy: 10 + sgprForEXECCopy: '$sgpr100_sgpr101' +body: | + ;
