I tried this patch to resolve lowering `nvvm.mma.sync` on bf16 operands for the
PR 13858 <https://github.com/openxla/iree/pull/13858>
nvvm.mma.sync A[%293, %295, %297, %299] B[%392, %394] C[%484, %485, %487,
%488] {layoutA = #nvvm.mma_layout<row>, layoutB = #nvvm.mma_layout<col>,
multiplicandAPtxType = #nvvm.mma_type<bf16>, multiplicandBPtxType =
#nvvm.mma_type<bf16>, shape = #nvvm.shape<m = 16, n = 8, k = 16>} :
(vector<2xbf16>, vector<2xbf16>, f32) -> !llvm.struct<(f32, f32, f32, f32)>
I fail to compile this patch. Please find the compilation error below:
