DESCRIPTION
-
ALEF is a concurrent programming language with a syntax like C's.
Kal,
val
and
8al
compile the named ALEF source
files
into SPARC, MIPS and
Intel 386 object files.
Source
files
have the extension
.l.
The ALEF source is passed through
cpp(1)
prior to compilation. Object files have the
normal extension for each architecture:
.k
for SPARC,
.v
for MIPS and
.8
for 386.
Up to
$NPROC
files
will be compiled in parallel.
The compiler options are:
-
-o obj
- Place output in file
obj
(ignored if there is more than one input file).
Default is to take the last element of the input pathname,
strip any trailing
.l,
and append the object file suffix.
- -a
- Write no object file, but produce an
acid(1)
program on standard output, comprising a set of type declarations
and functions to print those types.
- -aa
- Like
-a
but suppress output for types and functions declared in header files.
- -w
- Print warning messages for non fatal errors.
- -N
- Do not run the code optimizer.
- -c
- Do not compile code for
check
statements.
- -S
- Produce assembly language instead of object code as output.
By default, output goes to a file named by the
last element of the input pathname with
.l
replaced by
.s.
- -Dname=def
- -Dname
- Define the
name
to the preprocessor,
as if by
#define.
If no definition is given, the name is defined as
1.
- -Idir
- #include
files whose names do not begin with
/
are always
sought first in the directory
of the
file
argument,
then in directories named in
-I
options,
then in
/sys/include/alef,
and finally in
/$objtype/include/alef.
- -dc
- Produce various forms of debugging. The character
c
is an alphabetic.
The compiler recognizes several
#pragma
directives. The first,
#pragma lib,
is the same as in
2c(1).
The others have effect only when profiling is turned on by the
-p
option of the loader (see
2l(1)).
The directive
#pragma noprofile
disables the generation of profiling code for subsequently declared functions;
#pragma profile
enables it again.
The main use of these directives is
to avoid the profiling confusion caused by functions that do not explicitly return,
such as the task-switching functions in the run-time system.
Nonetheless, without support for profiling multi-process programs,
it remains difficult to profile Alef programs.
EXAMPLE
-
To compile and run on a SPARC the ALEF program in the current directory:
-
-
kal -w *.l
kl *.k
k.out
FILES
-
-
/sys/include/alef
- directory for
#include
files.
- /$objtype/lib/alef
- directory for ALEF libraries
