11 /// \brief This file contains signature information for runtime libcalls.
12 ///
13 /// CodeGen uses external symbols, which it refers to by name. The WebAssembly
14 /// target needs type information for all functions. This file contains a big
15 /// table providing type signatures for all runtime library functions that LLVM
16 /// uses.
17 ///
18 /// This is currently a fairly heavy-handed solution.
