With a few more debug print statements, the error appears unrelated to the use of `f16` primitives. The last print statement occurs in `LLVMModule`, just before the `PackedFunc` call to `(*faddr)(arg_values, arg_type_codes, ...)`. The print statement at the start of the TIR implementation (`"Start of function\n"`) does not get printed, so the compiled PrimFunc must not be entered at all. To verify this, I'm running a version of the test where both the input and output are `float32`. If this is the case, it may be related to [this issue](https://github.com/actions/runner-images/issues/10020#issuecomment-2220037354) in the github runners for Windows. From what I can tell, the Windows image shipped with a MSVC compiler newer than its MSVC runtime, causing incompatibilities between generated code and the runtime. The issue has a workaround in some cases, but several users have reported that the workaround is very fragile, and depends on (1) DLL load order, (2) whether any other program provided an older version of the MSVC runtime, and (3) whether the `C:\hostedtoolcache\windows` path contains leftover files from a previous CI run. -- This is an automated message from the Apache Git Service.
