/*
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
This will produce a .s file, something like
.file "foo.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.
