Introduction
|
|
.PP
|
|
This document
|
|
describes the process of installing Amsterdam Compiler Kit.
|
|
It depends on your combination of hard- and software how
|
|
hard it will be to install the Kit.
|
|
This description is intended for a PDP 11/44 running
|
|
.UX
|
|
Version 7.
|
|
Installation on other PDP 11's should be easy, as long
|
|
as they have separate instruction and data space.
|
|
Installation on machine's without this feature, like PDP 11/34,
|
|
PDP 11/60 requires extensive surgery on some programs and is
|
|
thought of as impossible.
|
|
Installation on VAX'en running BSD4.1 should also be easy.
|
|
See section 7 for installation on other systems.
|

|
Restoring tree
|
|
.PP
|
|
The process of installing Amsterdam Compiler Kit is quite simple.
|
|
It is important that the original Amsterdam Compiler Kit
|
|
distribution tree structure is restored.
|
|
Proceed as follows
|
|
.IP " -" 10
|
|
Create a directory, for example /usr/em, on a device
|
|
with at least 15 Megabytes left.
|
|
.IP " -"
|
|
Change to that directory (cd ...); it will be the working directory.
|
|
.IP " -"
|
|
Extract all files from the distribution medium, for instance
|
|
magtape:
|
|
\fBtar x\fP.
|
|
.IP " -"
|
|
Keep a copy of the original distribution to be able to repeat the process
|
|
of installation in case of disasters.
|
|
This copy is also useful as a reference point for diff-listings.
|
|
.LP
|
|
.bp
|
|
The directories in the tree contain the following information:
|
|
.sp 1
|
|
.nr PD 0
|
|
.IP "bin" 14
|
|
.br
|
|
the few utilities that knot things together.
|
|
See the section about "Commands".
|
|
.IP "lib"
|
|
.br
|
|
root of a tree containing almost all binaries and libraries used by
|
|
commands.
|
|
All files specific to a certain machine are collected in one subtree
|
|
per machine. E.g. "lib/pdp", "lib/z8000".
|
|
The names used here are the same names as used for subdirectories
|
|
of "mach".
|
|
.IP "lib/descr"
|
|
.br
|
|
Command descriptor files used by the program ack.
|
|
.IP "lib/LLgen"

.br
|
|
Files used by the LL(1) Parser-generator.
|
|
.br
|
|
.IP "etc"
|
|
.br
|
|
The main description of EM sits here.
|
|
Files (e.g. em_table) describing
|
|
the opcodes and pseudos in use,
|
|
the operands allowed, effect in stack etc. etc.
|
|
Make in this directory creates most of the files in "h"
|
|
and "util/data".
|
|
This make should only be called when the EM definition is
|
|
changed.
|
|
.IP "include"
|
|
.br
|
|
More or less system independent include files needed by modules
|
|
in the C library from lang/cem/libcc.
|
|
Especially needed for "stdio".
|
|
.IP "h"
|
|
.br
|
|

|
|
for all utilities
|
|
em_pseu.h pseudo instruction => compact mapping

.NH
|
|
Adapting ACK to your system
|
|
.PP
|
|
Before compiling the sources in the Kit some installation dependent
|
|
actions have to be taken.
|
|
Most of these are performed by an interactive shell script in the file
|
|
first in a directory of the same name.
|
|
.LP
|
|
These actions are:
|
|
.sp 1
|
|
.IP -
|
|
Automatically checking whether you included the ACK bin directory in your
|
|
shell PATH.
|
|
See also the section on "commands".
|
|
.IP -
|
|
Automatically setting the pathname of the parent directory in ../h/em_path.h.
|
|
See also the section on "pathnames".
|
|
.IP -
|
|
Asking you for the type of system you have
|
|
and creating the shell script "ack_sys" in the Kit's bin directory.
|
|
Several utilities make use of "ack_sys" to determine the type of
|
|
system you have.
|
|
The current choice is between:
|
|
.sp 1
|
|
.TS
|
|
c c c
|
|
l l l.
|
|
answer system type default machine
|
|
pdp_v7 PDP11 with sep I/D and version 7 pdp
|
|
vax_bsd4_1a VAX11 with BSD4.1a vax2
|
|
vax_bsd4_1c VAX11 with BSD4.1c vax2
|
|
vax_bsd4_2 VAX11 with BSD4.2 vax2
|
|
pc_ix IBM PC with PC/IX ix
|
|
m68_unisoft Motorola 68000 with Unisoft UNIX m68k2
|
|
m68_pmds Philips PMDS pmds
|
|
ANY Neither of the above m68k2
|
|
.TE
|
|
.sp 1
|
|
As mentioned before the installation on VAX'en and PDP11's should
|
|
be easy.
|
|
The pc_ix and m68 systems are also known to behave reasonably,
|
|
but the installation procedure has not been extensively tested.
|
|
For ANY you can use any name you fancy,
|
|
but the Kit will not be able to compile programs for your system.
|
|
If you want to do that you have to read the section about "compilation
|
|
on a different machine".
|
|
.IP -
|
|
Automatically setting the default machine for which code is
|
|
produced to your own type of system according to the table above.
|
|
This in done in the file "h/local.h".
|
|
See also the section 8.2.
|
|
.IP -
|
|
Automatically editing a few description files that tell
|
|
ACK to use your system's assembler.
|
|
On both the PDP and the VAX the Kit uses the native assembler and linker.
|
|
The description files in lib/pdp/descr, lib/vax2/descr and
|
|
lib/vax4/descr have to be altered to prevent
|
|
attempts to assemble programs with unsuitable assemblers.
|
|
The original descr files are copied to descr.orig.
|
|
.IP -
|
|
Automatically installing the special include directory for vax2.
|
|
This will only be done on VAX systems.
|
|
The shell scripts needed by ACK for the vax2 backend differ slightly
|
|
from the one issued by Berkeley.
|
|
.br
|
|
Note: this has only been tested under BSD4.1a.
|
|
.IP -
|
|
Automatically editing the system.h file in mach/vax[24]/libem.
|
|
Again, only on VAXen.
|
|
These files reflect whether you have BSD4.1a, BSD4.1c or BSD4.2.
|
|
.LP
|
|
.sp 1
|
|
Some actions still have to be done by hand.
|
|
.sp 1
|
|
.IP -
|
|
The VAX backends cannot be booted on systems
|
|
with a 16-bit address space systems.
|
|
The program lib/cgg needs more memory than available to transform
|
|
the table into files suitable for the C-compiler.
|
|
Therefore files tables1.h and tables1.c have been provided in
|
|
the directories mach/vax[24]/cg.
|
|
These must be copied to tables.h and tables.c on their respective
|
|
directories to get working code-generators for the VAX on PDP11's.
|
|
You will hardly be able to use these, because the
|
|
code generated by these programs cannot be
|
|
assembled and loaded without a native VAX assembler,
|
|
but its nice to be able to look at the code produced.
|
|
.IP -
|
|
The installation of the PUBMAC macro package is not done
|
|
automatically because you needs super-user privileges to do
|
|
that on most systems.
|
|
This macro package is used with several of the documents
|
|
provided in the Kit.
|
|
.IP -
|
|
UNIX V7 as originally distributed contains a few bugs that
|
|
prevent correct execution of some of the larger programs.
|
|
See the section named "Fixes for the UNIX V7 system"
|
|
about what to do.
|
|
.IP -
|
|
The manual files for the Kit can be copied to their
|
|
appropriate place in the system by giving the command "make install"
|
|
in the man directory.
|
|
.NH
|
|
Compiling the Kit
|
|
.PP
|
|
The next step in the installation process is to compile
|
|
the sources in the Kit and install them in their places
|
|
in the lib and bin directories.
|
|
.PP
|
|
Most directories containing sources have Makefiles
|
|
used to compile and install the programs in that
|
|
directory.
|
|
All programs needed for compilation and/or cross compilation
|
|
with the Kit are installed in the directories "bin" and "lib"
|
|
by these Makefiles.
|
|
These Makefiles adhere to a standard which is described in the
|
|
section 9.
|
|
.LP
|
|
You do not have to start all these Makefiles separately.
|
|
We wrote a shell script calling the make's needed to install
|
|
the whole Kit.
|
|
This script consists of the file TakeAction in the Kit's root
|
|
directory and a few files called Action in some directories.
|
|
The Action files describe in a very simple form which actions
|
|
have to be performed in which directories.
|
|
The default action is to start "make install".
|
|
The output of each make is diverted to a file called "Out"
|
|
in the same directory as the make was started in.
|
|
If the make was successful (return code 0) the Out file is removed
|
|
and the script TakeAction produces a small message telling you
|
|
that it succeeded in fulfilling its goal.
|
|
If the make was not successful (any other return code) the Out file
|
|
is left alone for further examination and a small message telling you
|
|
to look at that file is produced by TakeAction.
|
|
.LP
|
|
For some programs the scripts already know they can't be
|
|
installed on your type of system.
|
|
In that case they produce a message "Sorry, ....." and
|
|
happily proceed with further installation commands.
|
|
.PP
|
|
Compilation of the whole Kit might take anything from a few
|
|
hours to more than a day.
|
|
If you do not want to install libraries etc. for a particular
|
|
machine you can edit the file Action and remove the relevant entries.
|
|
.PP
|
|
If this compilation went reasonably successful you should be able
|
|
to use the Kit.
|
|
Read the next section and the manuals provided
|
|
with the Kit (in the man directory) on how to use it.
|
|
.NH 2
|
|
Problems you may meet
|
|
.NH 3
|
|
on Unisoft m68000 systems.
|
|
.PP
|
|
The Unisoft C compiler has a bug which impedes the correct
|
|
translation of the peephole optimizer.
|
|
For a more detailed description of this phenomenen see
|
|
the file "mach/m68k2/Unisoft_bug".
|
|
.NH 3
|
|
with backends
|
|
.PP
|
|
The backends for the PDP11, VAX with BSD4.1, Motorola 68000 and
|
|
Intel 8086 have been heavily used by ourselves and are well tested.
|
|
The backends for the other machines are known to run our own
|
|
test programs,
|
|
but might reveal errors when more heavily used.

We currently make the Kit available to our users by telling
|
|
them that they should include the bin directory of the Kit in
|
|
their PATH shell variable.
|
|
The programs will still work when moved to a different
|
|
directory or linked to.
|
|
Copying should preferably be done with tar, since links are
|
|
heavily used.
|
|
Renaming of the programs linked to \fIack\fP will not always
|
|
produce the desired result.
|
|
This program uses its call name as an argument.
|
|
Any call name not being \fIcc\fP, \fIacc\fP, \fIabc\fP, \fIpc\fP or \fIapc\fP will be
|
|
interpreted as the name of a 'machine description' and the
|
|
program will try to find a description file with that name.
|
|
The installation process will only touch the utilities in the Kit's bin
|
|
directory, not your own copies.

The commands \fBint\fP, \fBint22\fP, \fBint24\fP and \fBint44\fP
|
|
produce e.out files with EM machine code which must be interpreted.
|
|
The Kit contains two interpreters one running under PDP 11/V7 UNIX
|
|
and the PMDS system.
|
|
The first one can only interpret 2/2 e.out files,
|
|
the other takes 2/4 and 4/4 files.
|
|
The PDP 11 interpreter executes floating point instructions.
|
|
The interpreter on the PMDS traps if you try to use floating point.
|
|
.LP
|
|
The program \fBem\fP in the bin directory calls the appropriate
|
|
interpreter.
|
|
The interpreters are sought in the int22, int24 and int44
|
|
subdirectories of lib.
|
|
.NH
|
|
Compilation on a different machine.
|
|
.PP
|
|
The Kit be installed and used as a cross-compiler
|
|
for C and Basic programs on any UNIX machine.
|
|
The presence of most UNIX utilities is essential for compilation.
|
|
A few of the programs you certainly need are: C-compiler, Yacc, sed,
|
|
make and lex.
|
|
Except the Pascal compiler proper all programs
|
|
can be translated on a normal UNIX system, like V7, BSD4.1.
|
|
.PP
|
|
We know there are certain problems with System V.
|
|
Some of the character/string routines are named differently,
|
|
ctype(3) seems to have a different naming scheme.
|
|
The most annoying thing is that in printf format strings the
|
|
role of the format %03x is taken by something like %.3x.
|
|
Several programs suffer from this format change.
|
|
.NH 2
|
|
Backend
|
|
.PP
|
|
The existence of a backend with a system call library
|
|
for your system is essential
|
|
if you wish to produce executable files for that system.
|
|
Rewriting the system call library if the one supplied does
|
|
not work on your system is fairly straightforward.
|
|
If no backend exists for your CPU type you have to write one yourself
|
|
which is a major undertaking.
|
|
.NH 2
|
|
Pascal
|
|
.PP
|
|
When you can produce executable code it is also possible to boot the Pascal
|
|
Compiler,
|
|
which is written in Pascal itself.
|
|
The Kit contains the compact code files for the 2/2 and 2/4
|
|
versions of the Pascal compiler.
|
|
The current version of this compiler can only be used on machines
|
|
with a 16-bit word size and 16- or 32-bit pointers.
|
|
The Makefile automatically tries to boot the Pascal compiler
|
|
from one of these compact code files, if the compiler proves
|
|
unable to compile itself.
|
|
.NH 2
|
|
Universal assembler
|
|
.PP
|
|
The native assemblers and loaders are used on PDP-11 and VAX.
|
|
The description files in lib/*/descr for other systems use our
|
|
universal assembler.
|
|
The load file produced by this assembler is not directly
|
|
usable in any system known to us,
|
|
but has to be converted before it can be put to use.
|
|
The \fIcv\fP programs convert our a.out format into
|
|
executable files.
|
|
The \fIdl\fP programs present for some machines unravel
|
|
these our a.out files and transmit commands to load memory
|
|
to a microprocessor over a serial line.
|
|
The file man/a.out.5 contains a description of the format of
|
|
the universal assembler load file,
|
|
it might be useful to those who wish or need to write their
|
|
own conversion programs.
|
|
.LP
|
|
One warning has to be issued here.
|
|
The universal assembler a.out files contain integers and/or
|
|
longs with the bytes in the order your own system uses.
|
|
Copying these files to machines with a different byte order
|
|
will not always produce the desired results.
|
|
.NH 2
|
|
Compiling libraries
|
|
.PP
|
|
The Kit contains sources for part II and III of the C-library,
|
|
they have been grabbed from our V7 system and sometimes
|
|
altered in a EM dependent way or replaced altogether when the original
|
|
was in assembly.
|
|
These files can be used to make libraries for the Ack C-compiler.
|
|
The recompilation process uses a few include files.
|
|
The include directory in the EM home directory contains a few more
|
|
or less system independent include files.
|
|
Some backends, like the vax2 backend also need a few include files
|
|
of their own, replacing ones in /usr/include.
|
|
The include files are sought in lib/*/include.
|
|
The system dependent include files are fetched from /usr/include
|
|
on the system you use to recompile.
|
|
This may lead to several problems.
|
|
Sometimes the system differs so much from V7 that certain manifest constants
|
|
do not exist any more.
|
|
At other times these include files were written for a compiler without
|
|
a restriction on name length.
|
|
In that case - I've seen it happen - people tend to use differing
|
|
identifiers that are identical in the first eight characters.
|
|
All these problems you have to solve yourself,
|
|
the libraries are only included as an extra and too much system
|
|
dependent to give any guarantees.
|
|
.NH
|
|
Options
|
|
.NH 2
|
|
Default machine
|
|
.PP
|
|
There is one important option in h/local.h.
|
|
The utility \fIack\fP uses a default machine name when called
|
|
as \fIacc\fP, \fIcc\fP, \fIabc\fP, \fIapc\fP, \fIpc\fP or \fIack\fP.
|
|
The machine name used for default is determined by the
|
|
definition of ACKM in h/local.h.
|
|
The Kit is distributed with "pdp" as the default machine,
|
|
but the shell script "first" in the directory "first" alters this
|
|
to suit your own system.
|
|
There is nothing against using the Kit as a cross-compiler
|
|
and by default produce code that can't run on your own system.
|
|
But...., you have to alter the Makefile for the Pascal frontend
|
|
in that case.
|
|
That Makefile assumes that calling \fBapc\fP and \fBacc\fP will
|
|
produce a.out's that can run on your own system.
|
|
Change the definitions of ACC and APC in that Makefile according to your
|
|
needs.
|
|
.NH 2
|
|
Pathnames
|
|
.PP
|
|
Absolute pathnames are concentrated in "h/em_path.h".
|
|
Only the Pascal runtime system and the utility \fIack\fP use
|
|
absolute pathnames to access files in the Kit.
|
|
The tree is distributed with /usr/em as the working
|
|
directory.
|
|
The definition of EM_DIR in em_path.h should be altered to
|
|
specify the root
|
|
directory for the Compiler Kit distribution on your system.
|
|
This is done automatically the the shell script "first" in the
|
|
directory "first".
|
|
Em_path.h also specifies which directory should be used for
|
|
temporary files.
|
|
Most programs from the Kit do indeed use that directory
|
|
although some remain stubborn and use /tmp or /usr/tmp.
|
|
.LP
|
|
The shape of the tree should not be altered lightly because
|
|
most Makefiles and the
|
|
utility \fIack\fP know the shape of the ACK tree.
|
|
All pathnames in all Makefiles are relative, that is do not
|
|
have "/" as the first character.
|
|
The knowledge of the utility \fIack\fP about the shape of the tree is
|
|
concentrated in the files in the directory lib/*/descr and lib/descr/*.
|
|
.NH
|
|
Makefiles
|
|
.PP
|
|
Most directories contain a "Makefile".
|
|
Apart from commands applying to that specific directory these
|
|
files all recognize a few special commands.
|
|
When called with one of these they will apply the command to
|
|
their own directory and all subdirectories.
|
|
The special commands are:
|
|
.sp 1
|
|
.IP "install" 20
|
|
recompile and install all binaries and libraries.
|
|
.br
|
|
Some Makefiles allow errors to occur in the programs they call.
|
|
They ignore such errors and notify the user with the message
|
|
"~....... error code n: ignored".
|
|
Whenever such a message appears in the output you can ignore it
|
|
too.
|
|
.IP "cmp"
|
|
recompile all binaries and libraries and compare them to the
|
|
ones already installed.
|
|
.IP pr
|
|
print the sources and documentation on the standard output.
|
|
.IP opr
|
|
make pr | opr
|
|
.br
|
|
Opr should be an off-line printer daemon.
|
|
On some systems it exists under another name e.g. lpr.
|
|
The easiest way to call such a spooler is using a shell script
|
|
with the name opr that calls lpr.
|
|
This script should be placed in /usr/bin or EM_DIR/bin or
|
|
one of the directories in your PATH.
|
|
.IP clean
|
|
remove all files not needed for day-to-day use,
|
|
that is binaries not in bin or lib, object files etc.
|
|
.LP
|

|
|
.nf
|
|
.sp 1
|
|
make install
|
|
.sp 1
|
|
.fi
|
|
given as command in the home directory will cause
|
|
compilation of all programs in the directory and copying of the results
|
|
to the bin and lib directories.

Fixes for the UNIX V7 system
|
|
.PP
|
|
UNIX System V7 has a few bugs that prevent a part of or the whole Kit
|
|
from working properly.
|
|
To be honest, we do not know which of the following changes are
|
|
essential to the functioning of our Kit.
|
|
.PP
|
|
The file "doc/v7bugs.doc" gives for each of the following bugs
|
|
a small test program and a diff listing of the source files that have to be
|
|
modified.
|

|
|
and to check if the modifications are effective.

Testing
|
|
.PP
|
|
Test sets are available in Pascal, C, Basic and EM assembly.
|
|
.IP em 8
|
|
.br
|
|
The directory emtest contains a few EM test programs.
|
|
The EM assembly files in these tests must be transformed into
|
|
load files.
|
|
These tests use the LIN and NOP instructions to mark the passing of each
|
|
test.
|
|
The NOP instruction prints the current line number during the
|
|
test phase.
|
|
Each test notifies its correctness by calling LIN with a unique
|
|
number followed by a NOP which prints this line number.
|
|
The test finishes normally with 0 as the last number printed
|
|
In all other cases a bug showed its
|
|
existence.
|
|
.IP Pascal
|
|
.br
|
|
The directory lang/pc/test contains a few Pascal test programs.
|
|
All these programs print the number of errors found and a
|
|
identification of these errors.
|
|
.sp 1

We also tested Pascal with the Validation Suite.

|
|
The sub-directories in lang/cem/ctest contain C test programs.
|
|
The idea behind these tests is:
|
|
when you have a program called xx.c, compile it into xx.cem.
|
|
Run it with standard output to xx.cem.r, compare this file to
|
|
xx.cem.g, a file containing the 'ideal' output.
|
|
Any differences will point to implementation differences or
|
|
bugs.
|
|
Giving the command "run gen" or plain "run" starts this
|
|
process.
|
|
The differences will be presented on standard output.
|
|
The contents of the result files depend on the wordsize,
|
|
the xx.cem.g files on the distribution are intended for a
|
|
16-bit machine.
|
|
.IP Basic
|
|
.br
|
|
The directory lang/basic/test contains some forty basic programs.
|
|
Not all of these programs are correct, some have syntactic errors,
|
|
some simply don't work.
|
|
The Makefile in that directory attempts to compile and run
|
|
these tests.
|
|
If it compiles its output is compared to a file with suffix .g
|
|
which contains the output to be expected.
|
|
The make should be started with its standard input diverted
|
|
to /dev/null.
|
|
An example of the output od a make is present in the file Out.std.
