32. Bigloo
A practical Scheme compiler (4.3g)
User manual for version 4.3g
December 2019 -- Compiler description

32.1 C requirement

Instead of producing assembly code, Bigloo produces C code. This C code is ISO-C compliant [IsoC]. So, it is necessary to have an ISO-C compiler. The current version has been developed with gcc [Stallman95].

32.2 JVM requirement

In order to compile the Bigloo JVM back-end, you have to be provided with a JDK 1.2 or more recent (available at http://www.javasoft.com). The JVM must support for -noverify option because, by default, Bigloo produces JVM code that is not conform to the rules enforced by the Java byte code verifiers.

32.3 Linking

It is easier to use Bigloo for linking object files which have been compiled by Bigloo. An easy way to perform this operation is, after having compiled all the files using the -c option, to invoke Bigloo with the name of the compiled files.

When Bigloo is only given object file name as argument, it searches in the current directory and the directory named in the *load-path* list the Scheme source file in order to perform a correct link. Scheme source files are supposed to be ended by the suffix .scm. Additional suffixes can be added using the -suffix option. Hence, if source files are named foo1.sc and foo2.sc, a link command line could look like:

bigloo -suffix sc foo1.o foo2.o -o foo
Note: In order to understand how the Bigloo linkers operates and which libraries it uses, it might be useful to use the -v2 option which unveil all the details of the compilation and the link.

32.4 The compiler environment and options

There are four ways to change the behaviour of Bigloo. Flags on the command line, the option module clause runtime-command file and environment variables See Modules. When the compiler is invoked, it first gets the environment variables, then it scans the runtime-command file and, at end, it parses the command line. If the same option is set many times, Bigloo uses the last one.

32.4.1 Efficiency

In order to get maximum speed, compile with the -Obench option. This will enable all compiler optimization options and disable dynamic type checks. To improve arithmetic performance see next section.

32.4.2 Stack allocation

When the -fstack flag is enabled, the compiler may automatically replace some heap allocations with stack allocations. This may improve performance because stack allocations are handled more efficiently than heap allocations. On some cases, -fstack may also cause slow down or memory extra retentions. In this last case, when compile using -fstack the program will consume more memory. Unfortunately, this is nasty phenomenon is unpredictable (it depends on the nature of the source file).

32.4.3 Genericity of arithmetic procedures

By default, arithmetic procedures are generic. This means that it is allowed to use them with flonum and fixnum. This feature, of course, implies performances penalty. To improve performance, you may use specialized procedures (such as +fx, =fx, ... or +fl, =fl, ...) but, it is possible to suppress the genericity and to make all generic arithmetic procedures (= for example) fixnum ones. For this you must use the compiler option -farithmetic, or add the following module clause (option (set! *genericity* #f)) in your module declaration.

32.4.4 Safety

It is possible to generate safe or unsafe code. The safety's scope is type, arity, version and range. Let's see an example:

(define (foo f v indice)
   (car (f (vector-ref v indice))))
In safe mode, the result of the compilation will be:

(define (foo f v indice)
  (let ((pair 
        (if (and (procedure? f)
              ;; type check
              (= (procedure-arity f) 1))
              ;; arity check
           (if (vector? v)
              ;; type check
              (if (and (integer? k)
                    ;; type check
                    (>= k 0)
                    ;; range check
                    (< k (vector-length v)))
                    ;; range check
                (f (vector-ref v indice))
                (error ...))
              (error ...))
           (error ...))))
    (if (pair? pair)
       ;; type check
       (car pair)
       (error ...))))
It is possible to remove some or all safe checks. For example, here is the result of the compilation where safe check on types have been removed:

(define (foo f v indice)
  (let ((pair (if (= (procedure-arity f) 1)
             ;; arity check
             (if (and (>= k 0)
                   ;; range check
                   (< k (vector-length v)))
                   ;; range check
                (f (vector-ref v indice))
                (error ...))
             (error ...))))
     (car pair)))

32.4.5 The runtime-command file

Each Bigloo's user can use a special configuration file. This file must be named ``.bigloorc'' or ``~/.bigloorc''. Bigloo tries to load one of these in this order. This file is a Scheme file. Bigloo exports variables which allow the user to change the behavior of the compiler. All these variables can be checked using the -help2 option.

The Bigloo's runtime command file is read before the arguments are parsed.
