/*
Creating Template Files for New Platforms

Let the cc compiler help you get started.
Compile this program
    const unsigned int x[5] = {1, 2, 0xdeadbeef, 0xffffffff, 16};
with the -S option to produce assembly output.

For example, this will generate array.s:
gcc -S array.c

This will produce a .s file that may look like this:

    .file   "array.c"
    .version        "01.01"
gcc2_compiled.:
    .globl x
    .section        .rodata
    .align 4
    .type    x,@object
    .size    x,20
x:
    .long   1
    .long   2
    .long   -559038737
    .long   -1
    .long   16
    .ident  "GCC: (GNU) 2.96 20000731 (Red Hat Linux 7.1 2.96-85)"

which gives a starting point that will compile, and can be transformed
to become the template, generally with some consulting of as docs and
some experimentation.

If you want ICU to automatically use this assembly, you should
specify "GENCCODE_ASSEMBLY=-a name" in the specific config/mh-* file,
where the name is the compiler or platform that you used in this
assemblyHeader data structure.
