Pascal compiler for 386s

[Timothy M. Sigmon]

                        UVAPC/386 Fact Sheet

WHAT

uvapc/386 is an ISO standard Pascal compiler developed by the University
of Virginia's Academic Computing Center and the Department of Computer
Science.  uvapc/386 passes the ISO standard Pascal validation suite.
The compiler is written in C and has been ported to several other Unix
platforms.  uvapc/386 can generate the necessary information so that the 
System V Unix debugger, sdb, can be used.


SYSTEM REQUIREMENTS

    Processor

        Intel 80386 and 80387 or compatible.


    Operating System

        System V/386 Release 3.2 Version 2.1.  We believe it should run
        under SCO Unix and Interactive Unix, but it has not been tested
        under these operating systems.


    Software

        Requires or uses the following components:
                /bin/ld - the loader.
                /bin/as - the assembler.
                LIBDIR/crt1.o - the C startup routine
                LIBDIR/crtn.o - the C endup routine
                LIBDIR/mcrt1.o - the profiled C startup routine.
                LIBDIR/libc.a - the standard C library.
                LIBDIR/libm.a - the math library.


DOCUMENTATION

A man page as well as a 50 page document describing the internals of
uvapc are included with the distribution.  The document describing
the internals of uvapc is formatted using tbl and the mm macros.


DISTRIBUTION MEDIA

One 5-1/4 inch 1.2 MB floppy,  cpio format.


PURCHASE AND LICENSING INFORMATION

A source site license agreement must be signed.  To obtain the
license form, please see the contact information below.  For educational
institutions, a source site license costs $100.00.  Commercial source site
licenses are $1000.00.  Payment must accompany the executed site license,
and it must be in the form of a check made payable to the University of
Virginia.  Purchase orders and other forms of payment are not acceptable.

BENCHMARK INFORMATION

The following benchmark information was gathered on an SYP301, which 
is a 16MHz 80386 with an 80387 floating-point coprocessor.  The machine
has 4 megabytes of memory.  The C programs were compiled with the
command ``cc -o program program.c'', while the Pascal programs were
compiled with the command ``uvapc -t -o program program.p''.  The -t option
turns off the Pascal run-time checking.  All times are reported in seconds
and are the average of three compiles or runs.

LANGUAGE CONFORMANCE

The following table shows the behavior of the compiler with respect to
the British Standards Institute Pascal Validation Suite. Failure of the
two tests in the conformance sub-suite is normal behavior.
