zhanghaohit opened a new issue #8977: URL: https://github.com/apache/tvm/issues/8977
In [`src/tir/transforms/lower_tvm_builtin.cc`](https://github.com/apache/tvm/blob/f6a404447406f91ddf6195ac044dc1f0b0e867e7/src/tir/transforms/lower_tvm_builtin.cc#L116) ```c++ if (device_type_.defined()) { if (const auto* dev_type = device_type_.as<IntImmNode>()) { if (dev_type->value == kDLCPU) { int32_t constant_size = op->constant_allocation_size(); if (constant_size > 0 && constant_size * nbytes < runtime::kMaxStackAlloca) { return stmt; } } } } ``` If the condition `if (constant_size > 0 && constant_size * nbytes < runtime::kMaxStackAlloca)` is not true, the generated IR cannot work in VM runtime. Please see the detailed explanation here #8274. The bug is not triggering any problem for now, since this condition may be always true in our test. I'm not very sure this is a bug, but we need deeper investigation on this. -- This is an automated message from the Apache Git Service.
