Compiles, after fixing the obvious typos. I'm going to commit it to the mainline as obvious, since it takes Linux/SPARC from not-building to building; test results are abysmal, though. It looks as if we can't figure out the memory location variables are stored at correctly. They're being accessed in the unmapped 0x90000000 segment instead of 0x70000000, and not even at the right offsets. I'll look in to it more later. -- Daniel Jacobowitz Carnegie Mellon University MontaVista Software Debian GNU/Linux Developer Index: ChangeLog =================================================================== RCS file: /cvs/src/src/gdb/ChangeLog,v retrieving revision 1.1784 retrieving revision 1.1785 diff -u -p -r1.1784 -r1.1785 --- ChangeLog 2001/11/17 00:08:10 1.1784 +++ ChangeLog 2001/11/17 18:38:29 1.1785 @@ -1,3 +1,10 @@ +2001-11-17 Daniel Jacobowitz + + * Makefile.in: Add mips-linux-nat.c, mips-linux-tdep.c, + and sparc-linux-nat.c to ALLDEPFILES.
