/* Our basic approach to code generation is to map DWARF
|
|
|
|
|
operations directly to AX operations. However, there are
|
|
|
|
|
some differences.
|
|
|
|
|
|
|
|
|
|
First, DWARF works on address-sized units, but AX always uses
|
|
|
|
|
LONGEST. For most operations we simply ignore this
|
|
|
|
|
difference; instead we generate sign extensions as needed
|
|
|
|
|
before division and comparison operations. It would be nice
|
|
|
|
|
to omit the sign extensions, but there is no way to determine
|
|
|
|
|
the size of the target's LONGEST. (This code uses the size
|
|
|
|
|
of the host LONGEST in some cases -- that is a bug but it is
|
|
|
|
|
difficult to fix.)
|
|
|
|
|
|
|
|
|
|
Second, some DWARF operations cannot be translated to AX.
|
|
|
|
|
For these we simply fail. See
|
|
|
|
|
http://sourceware.org/bugzilla/show_bug.cgi?id=11662. */
