mole10 opened a new issue #5710: URL: https://github.com/apache/incubator-tvm/issues/5710
Hello all, I believe there is a bug within OpenCL codegen which results in a typo in data type identifiers. I am recently observing undefined type identifiers such as 'float44' and 'float88' in generated OpenCL codes. Here is an example. <pre><code> vstore4(((float44)(((__global float*)placeholder)[_1.s0],((__global float*)placeholder)[_1.s1],((__global float*)placeholder)[_1.s2],((__global float*)placeholder)[_1.s3])), 0, (__global float*)kernel_vec + ((((int)get_group_id(0)) * 1024) + (((int)get_local_id(0)) * 4))); </pre></code> I also found the similar problem in this post https://discuss.tvm.ai/t/bug-tvm-generate-wrong-opencl-code/6658. Here is my code to replicate this error: <pre><code> import numpy as np import topi import tvm target = tvm.target.create("opencl -device=mali") target_host = 'llvm' dshape = (1, 64, 224, 224) kshape = (64, 64, 3, 3) data = tvm.te.placeholder(dshape) kernel = tvm.te.placeholder(kshape) with target: conv = topi.mali.conv2d_nchw_spatial_pack(data, kernel, [1,1], [1,1,1,1], [1,1],"float32" ) sch = topi.mali.schedule_conv2d_nchw_spatial_pack([conv]) mod = tvm.build(sch, [data, kernel], target, target_host ) print("------opencl code------") print(mod.imported_modules[0].get_source()) </pre></code> The printed code will contain a 'float44' as shown in the example above. In addtion, my investigation of the cause leads to commit d2e58ad2fd92c09dffe064e4efbfc484cf2de6e5 https://github.com/apache/incubator-tvm/blob/d2e58ad2fd92c09dffe064e4efbfc484cf2de6e5/src/target/source/codegen_c.cc#L963 @tqchen @huochaitiantang @kevinthesun Could you please help to confirm if "t.lanes()" is unnecessary here.
