Programs for Linux ARMv6

This directory contains various small programs written in ARMv6
machine code. My goal is to learn enough about machine code to write
a machine code assembler that can assemble itself.

A couple scripts are included to fill a gap in software.

comp.sh:

  Print the hexidecimal value of a single instruction in GNU Assembly,
  with the help of the GNU Assembler and XXD.

assemble.sh:

  Create an executable from a file with hexidecimal bytes that might
  have comments. Limited to number bases supported by XXD.

You can assemble and link a program manually. The below command is for
the `echo' program:

  ./assemble.sh echo.hex echo

Alternatively, if you've installed the Thompson Shell, you can run the
following command to assemble and link all the programs:

  sh build.sh

The file `syscall.txt' contains the pretty names of Linux system call
numbers, for reference.
