That is correct. All the nodes have a hierarchy. So, for the math notes, 
we have:



nmat.pas - the base classes node - this includes functionality for the 
type checking (pass_typecheck), pass_1 (optional transformations at the 
tree level), optimizations (simplify)


ncgmat.pas - the generic code generator for the math nodes 
(pass_generate_code)


x86/nx86mat.pas - CPU-specific overrides for the math nodes (I'm using 
x86 as an example here, other CPUs have similar units in their 
CPU-specific directory)


x86_64/nx64mat.pas - another layer of CPU-specific overrides. This one 
is specific to x86_64 only, while the above is common to i8086, i386 and 
x86_64.



The same pattern applies to other node types, e.g. nadd.pas, ncgadd.pas, 
etc. for "add" nodes (actually +, -, *, and, or, xor and similar). 
nflw.pas, ncgflw, etc for control flow nodes (if..then..else, goto, 
try..except, for, while, etc.)

Hi.

I was browsing the FPC's 'compiler' directory and noticed a pattern of file 
name prefixed.


dbg*.pas - I can deduce 'debug'

But what does the 'nc*' and 'og*' and 'opt*' prefixes mean? eg: ogbase, 
gomap, ogelf etc.


Educated guess:

nc - node conversion 
og - object (file) generation

opt - optimizer

?
