[GitHub] [tvm] kparzysz-quic opened a new pull request, #12187: [JIT] Force finalization of JITed code, expose sf/hf runtime functions

[GitBox <gi...@apache.org>]

kparzysz-quic opened a new pull request, #12187:
URL: https://github.com/apache/tvm/pull/12187

   Code that handles fp16 and fp32 may end up calling builtins that do the conversions between these types. LLVM emits calls to `__truncsfhf2`, and `__extendhfsf2`, which are not present in TVM or TVM runtime. This creates two problems:
   - Problem 1: JITed code that does the conversions will fail because it calls non-existent functions.
   
   Adding these functions to libtvm.so/libtvm_runtime.so solves this part, but there is another issue:
   - Problem 2: JITed code may still not call these functions, because the generated object may not be fully resolved.
   
   To force full resolution, try to obtain an address of a non-existent symbol.
