IRQ pseudocode compiler

[Jiri Svoboda]

IRQ pseudocode in drivers is typically written as a C initializer (array of structs with designated members). This is not very concise/elegant. What's worse, often we need to substitute constants into the code, which is done by patching the instructions at run time by hand.

It would be much more elegant to define a text-based language for expressing this symbolic instruction code. Thus the driver could express the pseudocode as a simple string literal that would be then converted to the binary form. The language could allow for named constants, which would make the code much more readable.
