-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.
