    Compiling hello world program with the ZPU GCC toolchain

    +The ZPU comes with a standard GCC toolchain and an instruction set simulator. This allows compiling, running & debugging simple test programs. The Simulator has +some very basic peripherals defined: counter, timer interrupt and a debug output port. +

    Installation

    +
      +
    1. Install Cygwin. http://www.cygwin.com +
    2. Start Cygwin bash +
    3. unzip zputoolchain.zip +
    4. Add install/bin from zputoolchain.zip to PATH.
      +export PATH=$PATH:/install/bin +
    +

    Hello world example

    +The ZPU toolchain comes with newlib & libstdc++ support which means that many C/C++ programs can be compiled without modification. +

    + +zpu-elf-gcc -Os -zeta hello.c -o hello.elf -Wl,--relax -Wl,--gc-sections
    +zpu-elf-size hello.elf
    +     + +     +

    Optimizing for code size

    +The ZPU toolchain produces highly compact code. +
      +
    1. Since the ZPU GCC toolchain supports standard ANSI C, it is easy to stumble across +functionality that takes up a lot of space. E.g. the standard printf() function is a beast. Some compilers drop e.g. floating point support +from the printf() function and thus boast a "smaller" printf() when in fact they have a non-standard printf(). newlib has a standard printf() function +and an alternative iprintf() function that works only on integers. +
    2. The ZPU ships with default startup code that works across various configurations of the ZPU, so be warned that there is some overhead that will +not occurr in the final application(anywhere between 1-4kBytes). +
    3. Compilation and linker options matter. The ZPU benefits greatly from the "-Wl,--relax -Wl,--gc-sections" options which is not used by +all architectures(e.g. GCC ARM does not implement/need -Wl,--relax). +
    +

    Small code example

    + +zpu-elf-gcc -Os -abel smallstd.c -o smallstd.elf -Wl,--relax -Wl,--gc-sections
    +zpu-elf-size small.elf
    +
    +$ zpu-elf-size small.elf
    + text data bss dec hex filename
    + 2845 952 36 3833 ef9 small.elf
    +
    +     + +

    Even smaller code example

    +If the ZPU implements the optional instructions, the RAM overhead can be reduced significantly. +

    + +zpu-elf-gcc -Os -abel crt0_phi.S small.c -o small.elf -Wl,--relax -Wl,--gc-sections -nostdlib
    +zpu-elf-size small.elf
    +
    +$ zpu-elf-size small.elf
