I don't recall using "as" or "is" directly, but if I've done so, I
humbly apologise and will fix that right away.

On an extra note, the assembly language produced is not yet optimal,
so it may end up that an x86-specific implementation will be
beneficial. TIsNode contains a virtual method named
"DoVariableEnumCheck" that would allow such an extension, coupled
with returning "nil" that would defer code generation to
"pass_generate_code" (allowing this, but not overriding
"pass_generate_code", will trigger an internal error, because the
'is' node normally never allows it to be called). Nevertheless, even
if that is a no-go, it's making me a little excited to see if I can
find new peephole optimisations to implement. But until my old
x86_64 overhaul is accepted, rejected or reworked (at least to make
it successfully merge), I can't really make any new additions yet.
Some non-technical remarks regarding code formatting (I know the
compiler does currently not use a consistent style, but there is one
that is considered the de facto one (I should find the time to write
that down in the Wiki some time -.-) and new code should be added
following this):
- no spaces between operators and symbols, both in assignments and
expressions as well as parameter declarations
- local variables are written in lower case with the declarations as
"name1,name2,name3 : type"
- types are written in lower case
- method names are lower case with '_' as separator between words (so
your DoVariableEnumCheck would become do_variable_enum_check)
And one very important technical remark:
*No* "as" (or "is") inside the compiler. Use hard casts as you already
checked for the def type

Sven
