History
thorpej 1268b2dbc5 Add an x86_initialize_trampoline() function, similar to GCC 3.3, 
change INITIALIZE_TRAMPOLINE() to use it, and apply the following
patch to it (which I have already submitted to GCC 3.3):

	* config/i386/i386.c (x86_initialize_trampoline): Emit a call
	to __enable_execute_stack with the address of the trampoline
	if TRANSFER_FROM_TRAMPOLINE is defined.

Define a TRANSFER_FROM_TRAMPOLINE suitable for NetBSD targets, to enable
stack execution on target machines which can separate exec permissions for
a region:

	* config/netbsd.h (NETBSD_ENABLE_EXECUTE_STACK): Define.
	* config/alpha/netbsd.h (TRANSFER_FROM_TRAMPOLINE): Define
	as NETBSD_ENABLE_EXECUTE_STACK.
	* config/i386/netbsd-elf.h (TRANSFER_FROM_TRAMPOLINE): Ditto.
	* config/i386/netbsd.h (TRANSFER_FROM_TRAMPOLINE): Ditto.
	* config/sparc/netbsd-elf-common.h (TRANSFER_FROM_TRAMPOLINE): Ditto.
	* config/sparc/netbsd.h (TRANSFER_FROM_TRAMPOLINE): Ditto.

(A similar patch will be submitted to GCC 3.3.)

HOW TO BUILD A CROSS COMPILER
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[Section to be written.]

See also: http://www.netbsd.org/Documentation/cross/


IMPORTED VERSIONS
~~~~~~~~~~~~~~~~~
The following software is in gnusrc/gnu/dist/toolchain, in a unified build
structure:

    gcc-2.95.3
    binutils-2.11.2
    gdb-5.0


IMPORT STEPS
~~~~~~~~~~~~
1. All distributions were unpacked and all `.cvsignore' files were
   removed.

2. All files in gcc's `include' top level directory were removed from
   binutils's `include' top level directory (these are the libiberty
   include files).

   cd gcc-*/include; for f in *; do rm -f ../../binutils-*/include/$f; done

3. The gcc distribution was imported in one shot into
   gnusrc/gnu/dist/toolchain, including the recursive build structure.

4. The binutils distribution was stripped down to the following directories,
   with no files at the top level:

   bfd, binutils, gas, gprof, include, intl, ld, opcodes

5. Binutils was imported into gnusrc/gnu/dist/toolchain, which included
   only the subdirectories above.

6. The gdb distribution was stripped down to the following directories,
   with no files at the top level:

   gdb, mmalloc, readline, sim

7. Gdb was imported into gnusrc/gnu/dist/toolchain, which included only
   the subdirectories above.
