Message:
* Dwarf: Hide the implicit pointer from a function-parameter which is
passed
by reference, and dereference the (hidden) pointer in the DW_AT_location
block. This solves problems with function parameters defined as 'var'
----
Modified : /trunk/compiler/dbgdwarf.pas
--------------------------
But it seems that now, even in dwarf-3 objects are treated as pointer
again? (I can happily live with that. I just want to know)

I just noticed, a (good) change in dwarf 2, fpc trunk (ot I believe I
noticed)
in dwarf2, var param (param by ref) where encoded with an &
procedure a(var Foo: TObject):
ptype Foo
type = &TFOO = class : public TOBJECT
whatis Foo
type = &TFoo
Today, I looked at it, and the ampersands are gone?
In Dwarf they where never there, in dwarf the var-param alwas behaved
like normal var (you would never noticed the extra pointer layer) =>
seems dwarf caught up?
