SYSTEM OPTIONS

Following is the list of system-level options supported by
'gexace' (of the form <option name="..." value="..."/>),
and how they are translated to the vendor dependent Ace or
ESD files. "N/A" does not necessarily mean that the corresponding
Eiffel compiler does not support this facility, it could just
be that the facility is not parameterizable or is activated
from the command-line or from a separate tool (such as VETuner
for Visual Eiffel) rather than from the Ace or ESD file. When
an entry is marked "N/A" the option will be silently ignored
and nothing will be generated in the Ace or ESD file for this
option. Likewise when the name of an option specified in
an Xace file is not known by 'gexace'.

The DEFAULT section shows 'gexace' default value when this
option is not explicitely specified in the Xace file. It
can be different from the default value used by the various
Eiffel vendors in their Ace or ESD files.

For further details about each option, please refer to the
documentation provided with the Eiffel compilers.

NAME: address_expression

VALUES: true | false
DEFAULT: false
DESCRIPTION: Enable expressions of the form '$(s.to_c)' instead
  of having to declare 'a' of type ANY, and then having to 
  assign 's.to_c' to 'a' and passing '$a'. Turn this option on
  only if you have advanced knowledge of the garbage collector
  insides, since using this syntax illegally can lead to bugs
  very hard to trace.
NOTE: This form of syntax is not supported in Visual Eiffel and
  SmallEiffel.

NAME: fst_expansion_factor

VALUES: <value>
DEFAULT: 2
DESCRIPTION: Visual Eiffel supports dynamic binding via
  mechanism of FST (stands for Feature Selection Tables).
  Every entry in such table is a pair "class id (magic
  number) - feature address/attribute offset". In the general
  case binary searching is used to find the proper entry. To
  make this search faster and more efficient binary searching
  in the table can be replaced with direct linear access to
  array items (class id will be used as index of the array
  item). <value> is a positive integer number. When FST size
  multiplied by <value> is greater than the maximum class id
  in this FST, it is transformed into array.

=============================================================

CLUSTER OPTIONS

Following is the list of cluster-level options supported by
'gexace' (of the form <option name="..." value="..."/>),
and how they are translated to the vendor dependent Ace or
ESD files. "N/A" does not necessarily mean that the corresponding
Eiffel compiler does not support this facility, it could just
be that the facility is not parameterizable or is activated
from the command-line or from a separate tool (such as VETuner
for Visual Eiffel) rather than from the Ace or ESD file. When
an entry is marked "N/A" the option will be silently ignored
and nothing will be generated in the Ace or ESD file for this
option. Likewise when the name of an option specified in
an Xace file is not known by 'gexace'.

The DEFAULT section shows 'gexace' default value when this
option is not explicitely specified in the Xace file. It
can be different from the default value used by the various
Eiffel vendors in their Ace or ESD files.

For further details about each option, please refer to the
documentation provided with the Eiffel compilers.
