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.
 | 
						|
.PP
 | 
						|
On small machines, like the PDP-11, the Modula-2 front-end is only available
 | 
						|
for 2 byte integer, 2 byte pointer machines, so you can not cross-compile
 | 
						|
Modula-2 programs for f.i. a MC68000, on a PDP-11.

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"
 |

						|
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.

						|
.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:

For some of these, the installation procedure has not been tested, as
 | 
						|
we don't have them.
 | 
						|
For others, the installation procedure has only been tested with earlier
 | 
						|
distributions, as we don't have those systems anymore.
 | 
						|
However,
 | 
						|
the pdp_v7, vax_bsd4_1a, 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".

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.

On machines with a 16-bit address space, the C-compiler has no 
 |

builtin preprocessor. Arangements are made to this effect.

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.

The installation of the PUBMAC macro package is not done

The manual files for the Kit can be copied to their
 |

appropriate place in the system by giving the command "make install"
 |

running the installation of the

Kit itself.

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 && make clean".
 | 
						|
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 comment out the relevant entries.
 | 
						|
Lines starting with a '!' are comments.
 | 
						|
.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.

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,
 | 
						|
\fIocm\fP, \fIm2\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 subdirectories with the same name in mach contain the sources.

A * in the column headed 'fp' indicates that floating point can be used

point is only available under the '-fp' option. In this case, software

The commands \fBem22\fP, \fBem24\fP and \fBem44\fP
 | 
						|
produce e.out files with EM machine code which must be interpreted.
 | 
						|
The Kit contains three interpreters: one running under PDP 11/V7 UNIX,
 | 
						|
one for the M68000, running under the PMDS system, SUN systems, 
 | 
						|
the Mantra system, etc, and one, written in C and running on large machines.
 | 
						|
The first one can only interpret 2/2 e.out files,
 | 
						|
the second takes 2/4 and 4/4 files,
 | 
						|
and the last one takes 2/2, 2/4 and 4/4.
 | 
						|
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 em22, em24 and em44
 | 
						|
subdirectories of lib.
 | 
						|
The third interpreter is available on large machines as the program \fIint\fP
 | 
						|
in the bin directory.
 | 
						|
.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,
 | 
						|
\fIm2\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.
 | 
						|
.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.
 | 
						|
.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
 | 
						|
.LP
 | 
						|
Use the test programs to see if the errors are present in your system
 | 
						|
and to check if the modifications are effective.
 | 
						|
.PP
 | 
						|
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.
 | 
						|
.NH
 |

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
 | 
						|
.br
 | 
						|
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.
