 /* These weak stubs are provided for bitcode linking,
  * so that they are defined symbols.
- *
- * They will be overridden by the real functions in
- * libgcc_eh / libgcc_s / libcrt_platform
- *
- * for more information on these functions see:
- * http://www.nongnu.org/libunwind/docs.html
- * NOTE: libunwind uses slightly different function names:
- * e.g. _Unwind_DeleteException -> __libunwind_Unwind_DeleteException
- *
- * These two functions are pnacl specific:
- * _Unwind_PNaClSetResult0
- * _Unwind_PNaClSetResult1
