NAME

       8al, kal, val - ALEF compilers

SYNOPSIS

       8al [ option ...  ] [ file ...  ]
       kal [ option ...  ] [ file ...  ]
       val [ option ...  ] [ file ...  ]

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 If no definition is given, the name is defined as

       -Idir  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

SOURCE

       /sys/src/alef/port
	      machine-independent part

       /sys/src/alef/8, etc.
	      machine-dependent parts
