What is SDCC ? -

-
-
-SDCC is a Free -ware , retargettable, optimizing ANSI - C compiler. The -current version targets Intel 8051 based -MCUs, it can be retargeted for other 8 bit MCUs or PICs. The  entire -source code for the compiler is distributed under GPL. SDCC uses ASXXXX -& ASLINK a Free ware, retargettable assembler & linker. SDCC has -extensive -MCU (8051) specific language extensions, which lets it utilize -the underlying hardware effectively. The front end (parser) will be enhanced -to handle language extensions for other MCUs as and when they are targeted. -In addition to the MCU Specific optimizations SDCC also does a host of -standard optimizations like global sub expression -elimination, loop optimizations (loop invariant , strength reduction of -induction variables and loop reversing ), constant folding & propagation, -copy propagation, dead code elimination and jump tables for 'switch' statements. -For the Back end SDCC uses a global -register allocation scheme which should be well suited for -other 8 bit MCUs , the peep hole optimizer uses a rule based substitution -mechanism which is MCU independent. Supported data types are short -(8 bits, 1 byte), char (8 -bits, 1 byte) , int (16 bits, 2 bytes ), long -(32 bit, 4 bytes) & float -(4 byte IEEE).  SDCC also comes with a source -level debugger SDCDB, the current version of the debugger uses -Daniel's s51 simulator. The compiler also allows inline -assembler code to be embedded anywhere in a function. In -addition routines developed in assembly can also be called. SDCC also provides -an option to report the relative complexity of a function, these functions -can then be further optimized , or hand coded in assembly if need be.

Download [Sun Jan 16 12:08:15 CST 2000] -
  -
To compile SDCC, Linux ( -and other Unix ) users will need to install gcc or -any other C compiler. Windows 95/NT users will need to download -the full development version of CYGWIN32 from http://sourceware.cygnus.com/cygwin/ -. -Note that cygnus distributes CYGWIN32 in two packages you will need -the full development package, this contains the compiler and other -utilities that you will need to compile SDCC, I have not tried compiling -the system with any other compiler under MS/Windows. -

Version 2.1.8 onwards will be distributed in *.tar.gz -format, the installation procedure will also change. Installation section -of the  documentation has been updated to include the new procedure. -Click here to download  sdcc-2.1.9Ga.tar.gz - in -the new distribution format. This distribution also contains Daniel's simulator -. -

Binary distribution -of Version 2.1.9Ga for Windows is available -. The distribution is compiled to run from the directory /usr/local. Gunzip -& untar the binary distribution at the root (/) directory of the partition/drive -you want to install the software on. The source distribution of this version -compiles with CYGWIN. Click here to view more -detailed installation instructions for Win95/NT (provided by Michael -Jamet mjamet@computer.org). -

A binary distribution of the package for DOS can be downloaded -from SET's  page. -

Michael Hope <michaelh@earthling.net> is working on -a Z80 target ,a snapshot of which can be downloaded by clicking -here. -

The debugger works the DDD (Data Display debugger), Terry Porter <tp@gronk.apana.org.au> -has a screenshot and a brief HOWTO at http://www.odyssey.apana.org.au/~tjporter/ddd_sdcc.gif -

An alternate simulator & source level debugger can be downloaded -from Jens Altmann's JSIM page http://home.t-online.de/home/Jens.Altmann/jsim-e.htm -

Older versions can be downloaded -from Marcus Alanen's Page. -

-Known Problems -
-
-
  • -MS/Windows Users note that due to some -bugs in the CYGWIN runtime library the compiler generated temporary files -are NOT cleared from the /tmp directory, -these have to be manually deleted.
    • - -
  • ---xstack options not yet fully implemented.
    • - -
  • -first storage class specified overrides -in declarations . e.g.,
    • - -
    short xdata x, idata y.
    -will declare both x & y in xdata -space. The work around for this is to declare variables with different -storage classes separately e.g.. -
    xdata short x; -
    idata  short y;

    -What IDE to use ? -
      -
    I recommend using XEmacs, -it is free and is also a really GREAT editor. Linux / Unix users can download -binaries for their specific platforms from ftp://ftp.xemacs.org -.  Windows 95/98/NT Users , can download binaries from ftp://ftp.xemacs.org/pub/xemacs/binary-kits/win32/ -

    The interface files required for the debugger to interact -with XEmacs is distributed with the source code.

    -Click on this sandeep.dutta@usa.netto -send me an email, also send an email -to the mailing list for the benefit of other -users .Bugs will be fixed according to their severity. I will update the -Known Problems section. The compiler alone without the assembler , linker, -Preprocessor & garbage collector is about 40,000 lines of blank skipped -code, as with any project of this size there are bound to be bugs, I will -try me level best to fix them as quickly as I can . If you can trace the -bug and fix it, please do so, do  send me a copy of the fixed source -code so I can update my copy.

    -Notes for Users of Version 1.xx
    - -
    -
    -For the benefit of  users of the previous Version, I -have kept the parser almost identical, I have added a few features, but -the programs developed using the first version should compile without change -with the new version. The command line options however have changed, the -compiler will generate a warning when it encounters an older option and -prompt you with the new option.
    - -
    -Version 2.xx is a almost a complete rewrite, it is much more -stable and ANSI Compliant than the previous version.
