Patch: Add a29k-protos.h file
- To: egcs-patches at egcs dot cygnus dot com
- Subject: Patch: Add a29k-protos.h file
- From: "Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>
- Date: Wed, 12 Jan 2000 19:34:58 -0500 (EST)
Tested by building cc1 configured as an i686-pc-linux-gnu ->
a29k-unknown-bsd cross compiler.
Note to the reviewer:
Please look at the recursive calls to a29k_set_memflags_1 which had
missing argument that the prototype uncovered. I simply added the
parameter from the a29k_set_memflags_1 into the call it makes to
itself. Please double check this is correct.
Okay to install?

* a29k-protos.h: New file.
* a29k.c: Include tm_p.h. Add static prototypes. Fix compile
time warnings.
* a29k.h: Move prototypes to a29k-protos.h. Fix compile time
warnings.
