[PATCH/i386newframe] amd64newframe

[Andreas Jaeger]

Mark,

building the kettenis-newframe-branch on x86-64 I get:

make[1]: *** No rule to make target `inux-proc.o', needed by `libgdb.a'.  Stop.
make[1]: Leaving directory `/usr/src/aj/gdb-test/build/gdb'
make: *** [all-gdb] Error 2


Note the following:
./config/i386/x86-64linux.mh:   proc-service.o thread-db.o lin-lwp.o inux-proc.o gcore.o 

After fixing this problem, gdb build fine but running it I got:

byrd:/usr/src/aj/gdb-test/build/gdb:[0]$ ./gdb ~/tmp/a.out

And this also:

A problem internal to GDB has been detected.  Further
debugging may prove unreliable.

I don't have time to go into details here but hope that Michal can.
