- This is GDB, a source-level debugger intended for GNU,
- presently running under un*x.
- Before compiling GDB, you must set three files according to
- the kind of machine you are running on.
- param.h must be set up to #include an m- file for the machine.
- The m- files written so far are m-vax.h, m-sun2.h and m-sun3.h.
- (I believe that it is the operating system version and not
- the cpu type which determines which of the two is right on a Sun.)
- This file contains macro definitions that express information
- about the machine's registers, stack frame format and instructions.
- initialize.h must be set up to #include an m-...init.h file.
- There are two of them written: m-vaxinit.h and m-suninit.h.
- This file defines one macro, which says how to round up from the
- address of the end of the text of one .o file to the beginning of
- the text of the next .o file.
- pinsn.c must be set up to include the instruction printer for
- your cpu type. The two printers that exist are vax-pinsn.c
- and m68k-pinsn.c.
- `Makefile' must be changed to say `OBSTACK = obstack.o' instead of
- `OBSTACK=-lobstack' (unless you want to install obstack.o as
- /lib/libobstack.a).
- Once these files are set up, just `make' will do everything,
- producing an executable `gdb' in this directory.
