Fixed! Thanks again Marģers.

Oh yes, that's a silly mistake! Easy enough to fix hopefully.

FPC has JIT backends like JVM.
But that is just the backend, FPC still works only at compile time, so
no JIT at runtime possible. Is it?
Hmm, yes. You could maybe interface to the JVM and compile java that
way. But I don't eve
On a related note, I do wonder where pure functions might help with
JIT. It depends on what Florian and the other administrators and
developers seek, but currently I aim for my pure function implementation
to fulfil both standard properties (1. same output for the same
input(s), and 2. no side
In the case of JVM, the JIT compiler is specific to Java, I think.
Normally JIT requires the source code to be compiled into an
intermediate bytecode first (e.g. Java bytecode or the Common
Intermediate Language (.NET)).

Aah, thanks Marco. I still have some things to learn about FPC!

The main concept of pure functions is that they have no side-effects
(e.g. don't affect a global state or rely on I/O) and are analogous to a
mathematical function. The main things to draw from it are that for
constant inputs, the output is deterministic and can be calculated at
compile time (

Fixed 2 and 3.
- 2 was due to not handling block nodes properly when they didn't have
any statements (data-flow analysis stripped the procedure completely
clean since no result was set), hence an access violation occurred while
accessing a node that was nil.
- 3 was a two-fold problem:

Hi Marģers,
Thanks for the feedback!
Assigning the results of pure functions to constants has not yet been
developed. I had planned to add it once the bulk of pure functions
(i.e. the current merge request) had been approved since it requires
some additional work (specifically what happens i
1. pure function value to constants function foo(i:longword):longword; pure;
begin foo:=9; end; const bar = foo( 8 ); //-- not allowed.. but i expect
this to work! jar : longword = foo( 7 ); //-- and this as well 2. this
does not end grasefully function foo (i:longword):shortstring;
