#
# Perl script to convert a standard distribution directory for gcc into
# a NetBSD source tree.
#
# This is done as a script so that as each distribution is released,
# only changes from the previous one need to be dealt with as
# modifications to this script and related files. This should
# reduce the cost of updating from a new release of gcc by an
# order of magnitude (or more?)
#
# This script requires two environment variables set:
# SRCDIR - gcc source directory from FSF
# TARGETDIR - name of the high level directory to make
#
# Written by Phil Nelson, November 22, 1995. (for gcc-2.7.1)
#
# Updated November 29, 1995 for gcc-2.7.2
# Updated May 13, 1997 for gcc-2.7.2.1
# Updated May 14, 1997 for gcc-2.7.2.2
# Updated Oct 21, 1997 to complete objc-support (Ignatios Souvatzis)
# Updated Oct 24, 1997 to fix the m68k trampolines (Ignatios Souvatzis)
#
# This is currently updated for gcc-2.7.2.2. Newer versions of gcc
# should have this script and related files updated.

/* VERY BIG NOTE : Change of structure alignment for RiscBSD.
There are consequences you should be aware of */
/* Normally GCC/arm uses a structure alignment of 32. This means that
structures are padded to a word boundry. However this causes
problems with bugged NetBSD kernel code (possible userland code
as well - I have not checked every binary).
The nature of this the bugged code is to rely on sizeof() returning
the correct size of various structures rounded to the nearest byte
(SCSI and ether code are two examples, the vm system is another)
This code starts to break when the structure alignment is 32 as sizeof()
will report a word rounded size.
By changing the structure alignment to 8. GCC will conform to what
is expected by NetBSD.
This has several side effects that should be considered.
1. Structures will only be aligned to the size of the largest member.
i.e. structures containing only bytes will be byte aligned.
structures containing shorts will be half word alinged.
structures containing ints will be word aligned.
This means structures should be padded to a word boundry if
alignment of 32 is require for byte structures etc.
2. A potential performance penalty may exist if strings are no longer
word aligned. GCC will not be able to use word load/stores for copy
short strings.
This modification is not encouraged but with the present state of the
NetBSD source tree it is currently the only solution to meet the
requirements.
