 SPIR-V Instructions Mapped to LLVM Metadata
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 Some SPIR-V instructions don't have a direct equivalent in the LLVM IR language. To
 address this, the SPIR-V Target uses different specific LLVM named metadata to convey
 the necessary information. The SPIR-V specification allows multiple module-scope
