This directory contains tests for several parts of the compiler and RTL


--------------------------------------------------------------------
                      Code generator
--------------------------------------------------------------------
These tests should be considered unitary, as they only verify
simple cases of the code generator. Used for porting to other
architectures. Tries to validate all possible Location types
valid for that node. They are based on tests on these
reference platforms:
  Borland Pascal v7.01
  Delphi 3.0
  Delphi 4.0
  Delphi 6.0 Personal Edition

'Natural type' is a signed 32-bit value on 32-bit architectures.
'Natural type' is a signed 64-bit value on 64-bit architectures.
