Hello,
tests/tbf/tb0002.pp is intended to fail, but currently it fails because the VMT symbol
(VMT_$P$PROGRAM_$$_TA) is unresolved while linking. Shouldn't compiler detect usage of typeof() on
an object type without VMT and report error at compile stage instead?

Hi,
I've implemented an optimization that reorders the instance fields of
Delphi-style classes (and only of Delphi-style classes) to minimise memory
gaps caused by alignment differences and odd sizes. The effect is the same

does this optimization
also apply on systems that require proper alignment for memory accesses?
Well, yes, otherwise the optimization would simply consist of removing all
alignment padding and there would be no need to reorder the fields.

0.01% more performance ?
Cache related optimizations are VERY hard to measure and depend on
overall context and used architecture. But as the L1-cache is one of the
most performance

So you take away the concept of cursor. That is a radical change.
