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 VAX running BSD 4.1
|
|
.UX
|
|
\.
|
|
Installation on VAX BSD4.2/4.3 systems,
|
|
Sun-2 or Sun-3 systems running Release 3.0 or newer, and some System V systems
|
|
should be easy.
|
|
Installation on PDP 11's running
|
|
.UX
|
|
Version 7, BSD 2.8, or 2.9
|
|
should also 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.
|
|
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 25 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 subtrees
|
|
of "mach".
|
|
.IP "lib/descr"
|
|
.br
|
|
Command descriptor files used by the program ack.
|

|
|
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/_tail_cc"

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
|
|
.I 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 \-
|

Discovering how to call
|
|
.I cc

library.
|
|
.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.

|
|
For some of these, the installation procedure has not been tested, as
|
|
we don't have them. However,
|
|
the pdp_v7, vax_bsd4_1a, pc_ix, sun3 and m68 systems are known to behave
|
|
reasonably.
|
|
The Sun systems should run Release 3.0 or newer.
|
|
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 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 \-
|
|
The VAX backend 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 directory mach/vax4/cg.
|
|
These must be copied to tables.h and tables.c
|
|
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.
|
|
The same problem occurs for the m68k2 backend and the m68020 backend,
|
|
and the same solution is chosen.
|
|
.IP \-
|
|
On machines with a 16-bit address space, the C-compiler has no
|
|
builtin preprocessor. Arangements are made to this effect.
|
|
.IP \-
|
|
On the PDP,
|
|
.I ranlib
|
|
is not used, because it does not work properly,
|
|
at least, on our 2.9 BSD system it does'nt.
|
|
This is done by creating a dummy shell script
|
|
.I ranlib
|
|
in the ACK bin directory.
|
|
If you are sure that your
|
|
.I ranlib
|
|
does work properly, you can just remove the shell script before
|
|
installing the Kit.

Some actions still have to be done by hand.

|
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.

UNIX V7 as originally distributed contains a few bugs that
|
|
prevent correct execution of some of the larger programs.
|

Berkeley 2.8 or 2.9 may also have some of these bugs.

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, but only

|
|
running the installation of the
|
|
Kit itself.
|
|
.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.

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 one for the M68000, running under the PMDS system, SUN systems,
|
|
the Mantra system, etc.
|
|
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 for the M68000 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 for the Pascal compiler proper all programs
|
|
can be translated on a normal UNIX system, like V7, BSD4.1.
|
|
.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, 4/4 and 2/4
|
|
versions of the Pascal compiler.
|
|
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/loader, link editor
|
|
.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 and for most machines our link editor.
|
|
The load file produced 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
|
|
our a.out files and transmit commands to load memory
|
|
to a microprocessor over a serial line.
|
|
The file man/ack.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.
|
|
Also, a module is included to read and write our a.out format.
|
|
See modules/man/object.3.
|
|
.NH 2
|
|
Compiling libraries
|
|
.PP
|
|
The Kit contains sources for part II and III of the C-library.
|
|
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 the include files
|
|
it needs.
|
|
An effort has been made to make the part III stuff as system independent as
|
|
possible.
|
|
.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, \fIocm\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 "vax4" 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 utilities \fIack\fP and \fILLgen\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
|
|
Example:
|
|
.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. Berkeley 2.8 and/or 2.9 may also suffer from this
|
|
problem.
|
|
To be honest, we do not know which of the following changes are
|
|
essential to the functioning of our Kit. The change to "ld" is.

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.
|
|
.IP 1
|
|
Bug in the C optimizer for unsigned comparison
|
|
.nr PD 0
|
|
.IP 2
|
|
The loader 'ld' fails for large data and text portions
|
|
.IP 3
|
|
Floating point registers are not saved if more memory is needed.
|
|
.IP 4
|
|
Floating point registers are not copied to child in fork().
|
|
.nr PD 1v

|
|
Use the test programs to see if the errors are present in your system
|
|
and to check if the modifications are effective.

|
|
You may also have to change /usr/src/cmd/cc.c (/bin/cc) to pass the
|
|
.B -i
|
|
flag to
|
|
.I ld.
|
|
Also, /usr/src/cmd/ld.c (/bin/ld) may have to be changed to increase the
|
|
number of library positions it can hold.
|
|
On our (2.9 BSD) version, this is the constant
|
|
.I NROUT.
|
|
It must be at least 400.
|
|
This may require separate I&D.
|
|
Also, our version does not check that the table does not overflow.

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
|
|
.ti +4
|
|
We also tested Pascal with the Validation Suite.
|
|
The Validation Suite is a collection of more than 200 Pascal programs,
|
|
designed by Brian Wichmann and Arthur Sale to test Pascal compilers.
|
|
We are not allowed to distribute it, but you may
|
|

.IP C

|
|
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
|
|
32-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 of a make is present in the file Out.std.
