25 | /* Please refrain from exposing the world to the internals of tc-hppa.c |

29 | ||
30 | Also refrain from adding any more object file dependent code, there is | |
31 | already far too much object file format dependent code in this file. | |
32 | In theory this file should contain only exported functions, structures | |
