PROGRAM:
NAME
s2cc - Scheme to C compiler
SYNTAX
s2cc [ option ] ... file ...
DESCRIPTION
The s2cc command (previously known as scc) invokes a Scheme compiler which accepts the
language defined in the essential portions of Revised4 Report on the Algorithmic Language
Scheme, with minor constraints and some additions. The compiler produces C source files
which are then compiled using the system's C compiler to produce conventional .o and a.out
files. The C code produced by this compiler may be intermixed with other C code or code
written in other languages.
OPTIONS
These options are accepted by s2cc. Other options will be assumed to be options of the
system's C compiler and they will be passed to it when it is invoked.
-cc C compiler Compile the Scheme compiler produced C code with C compiler. If this
flag is not supplied, then the C compiler cc will be used.
-C Compile the Scheme programs found in the files source.sc and leave the
resulting code in source.c files. No further operations are performed.
-I directory Specifies a directory to be searched by include for source files.
-f symbol value Define the compile-time constant symbol to value. This is equivalent to
the construct (define-constant symbol value) appearing in the Scheme
source.
-i Combine the source and object files into a Scheme interpreter. The
module name for each Scheme source file is automatically determined.
Module names for previously compiled modules must be specified using the
-m option.
-m module-name Specifies the name of a previously compiled module. Note that the
Scheme compiler will downshift the alphabetic characters in the module-
name. Modules are initialized in the order that the -m flags appear.
-Ob Optimize code by omitting bounds checks on vectors and strings.
-Og Optimize code by omitting stack trace-back code.
-On Optimize code by assuming that all numbers are fixed point.
-Ot Optimize code by omitting type error checks.
-pg Produce profiled code for run-time measurement using gprof(1). The
profiled library is used in lieu of the standard Scheme library.
-scgc statflag Enables garbage collection statistics. If set to 1, then garbage
collection statistics will be printed. The default is 0, that will
result in no statistics.
-sch heap Specifies the compiler's initial heap size in megabytes. The default is
system dependent.
-scl percent Specifies the percent of the heap allocated after a generational garbage
collection that will force a full collection. The default is 40.
-scmh heap Specifies the compiler's maximum heap size in megabytes. The default is
five times the initial size of the heap.
-LIBDIR directory
Specifies a directory containing the files: predef.sc, objects.h,
libs2c.a, and optionally libs2c_p.a.
-log Logs information internal to the compiler to the C source file produced
by the compiler. Each type of information is controlled by a flag:
-source, -macro, -expand, -closed, -transform, -lambda, -tree, -lap,
-peep. The flag -log is equivalent to specifying the flags: -source,
-macro, -expand, -closed, -transform, -lambda, -tree.
ENVIRONMENT VARIABLES
The items controlled by -sc.. flags can also be controlled by environment variables. If
both the flag and the environment variable are provided, then the flag's value will be
used.
SCGCINFO Controls the reporting of garbage collection statistics to the standard
error file. If set to 1, then garbage collection statistics will be
printed. The default setting is 0 that will not print the statistics.
SCHEAP Specifies the initial size of the heap in megabytes. The default heap
size is system dependent.
SCLIMIT Specifies the percent of the heap allocated after a generational garbage
collection that will force a full collection. The default is 40.
SCMAXHEAP Specifies the maximum size of the heap in megabytes.
INPUT FILES
Following the command options come one or more file names.
name.sc Scheme source. Scheme source files will be compiled into C files with
the name name.c.
name.c C source.
name.s Assembly language source.
name.o Object file which may have been generated by any compiler.
name.a Object file archive which may have been generated by any compiler.
DIAGNOSTICS
The disgnostic messages produced by the compiler are printed on the standard error file.
