First minor snag, fpc_dynarray_insert, fpc_dynarray_concat can allocate new
arrays like SetLength can. Do we need to make aligned variants for these also?
Using array + operators there is no possibility to set alignment.
var
a, b: array of integer;
begin
a += [1]; // no way to set alignment for a
insert(1, b, 0); // no way to set alignment for b
end.
Some options:
1) ignore the problem
2) make extra syntax like:
a: array of integer; alignment = 64;
3) make another function to allocate an empty array that sets alignment
SetAlignment(a, 64);
An empty array is Nil, changing that would lead to a whole different can
of worms.
4) for insert/concat make variants like InsertAligned() and ignore + operators
for aligned arrays
Ignoring something is not an answer. At least there'd need to be a
runtime error.
Thinking about it maybe it would be better to follow Anthony's idea with
the record and not try to adjust/extend a language mechanism that wasn't
geared for that.
