1134198Sjdp/// \brief This file contains signature information for runtime libcalls.
1296516Sru///
1334198Sjdp/// CodeGen uses external symbols, which it refers to by name. The WebAssembly
1496530Sru/// target needs type information for all functions. This file contains a big
15217375Sdim/// table providing type signatures for all runtime library functions that LLVM
1696530Sru/// uses.
17217375Sdim///
18217375Sdim/// This is currently a fairly heavy-handed solution.
