I have a question about gengtype and GTY. I was looking at adding some code to mips.c and it occurred to me that that file was getting very large (19873 lines). So I wanted to add a new .c file instead but that file needed some types that were defined in mips.c and not in a header file. Specifically it needed the MIPS specific machine_function structure that is defined in mips.c with:
struct GTY(()) machine_function {.... I think I could just move this to mips.h and things would be fine but I didn't want to do that because mips.h is included in tm.h and is visible to the generic GCC code. Currently machine_function is not visible to the generic GCC code and so I wanted to put machine_function in a header file that could only be seen/used by mips specific code. So I created mips-private.h and added it to extra_headers in config.gcc. The problem is that if I include mips-private.h in mips.c instead of having the actual definition of machine_function in mips.c then my build fails and I think it is due to how and where gengtype scans for GTY uses. I couldn't find an example of a platform that has a machine specific header file that was not visible to the generic GCC code and that has GTY types in it so I am not sure what I need to do to get gengtype to scan mips-private.h or if this is even possible (or wise).
