Where can I find details of the input to the back-end?

The node tree contains the parsed instructions, and their argument descriptors should refer to the related variables and types (see node.pas for an start). You'll have to implement the code generation at least for the basic node types (assignment, operators, calls), see cgbase.pas.

Hint: the first few characters of the unit names describe the type:
aasm - assembler (aasmtai.pas)
cg - code generation (cgobj.pas)
n - nodes (node.pas)
p - parser
