Compiler description
Chapters
### 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 Running .NET programs on Microsoft .NET platforms
Bigloo uses Portable.NET assembler and linker to produce .NET binaries. As such, produced binaries are linked and signed against Portable.NET runtime libraries and are rejected by Microsoft .NET platforms. In order to run Bigloo .NET binaries on Microsoft .NET platforms, binaries must first be disassembled and then reassembled and linked against Microsoft runtime libraries. The pnet2ms utility automates this process. Before the first use of pnet2ms, a public+private key pair must first be registered to the "Bigloo" container. You may either use the provided pair in the bigloo.dotnetkey file or generate your own using:
              sn -k bigloo.dotnetkey
The pair must be registered using:
              sn -i bigloo.dotnetkey Bigloo
The pnet2ms program can be ran with:
      pnet2ms myprogram.exe
Additional command-line options are:
      -initlocals     force all local variables to be initialized to their
                      default value upon function entrance
                      (for PEVerify to succeed)
      -k              Keep intermediate files
      -register       Register DLLs in the Global Assembly Cache
      -v              Enable verbose mode
      -v2             Enable very verbose mode
      -v3             Enable very very verbose mode
### 32.4 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.
### 32.5 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.
### 32.5.1 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.
### 32.5.2 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).
### 32.5.3 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.
### 32.5.4 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)))
### 32.5.5 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.
### 32.5.6 The Bigloo command line
If no input file is specified, Bigloo enters its interpreter. Here is the exhaustive list of Bigloo options and configuration variables:
