URL: https://github.com/llvm/llvm-project/commit/a7d6593a0a17a1e7f46a3c9cd5c4aeeb7dfc6e0a DIFF: https://github.com/llvm/llvm-project/commit/a7d6593a0a17a1e7f46a3c9cd5c4aeeb7dfc6e0a.diff LOG: Add missing roundtointegral builtin functions for some FP instructions to be generated from C-written codes To generate FROUND instructions in https://reviews.llvm.org/D143982, we need to use llvm intrinsics in IR files. Now I add some corresponding builtin functions to make sure these roundtointegral instructions can be generated from C codes.
