Description:
|
||
Implements conversion of lexer tokens to machine-dependent numerical
|
||
form and accordingly issues diagnostic messages when necessary.
|
||
|
||
Also, this module, especially its .h file, provides nearly all of the
|
||
information on the target machine's data type, kind type, and length
|
||
type capabilities. The idea is that by carefully going through
|
||
target.h and changing things properly, one can accomplish much
|
||
towards the porting of the FFE to a new machine. There are limits
|
||
to how much this can accomplish towards that end, however. For one
|
||
thing, the ffeexpr_collapse_convert function doesn't contain all the
|
||
conversion cases necessary, because the text file would be
|
||
enormous (even though most of the function would be cut during the
|
||
cpp phase because of the absence of the types), so when adding to
|
||
the number of supported kind types for a given type, one must look
|
||
to see if ffeexpr_collapse_convert needs modification in this area,
|
||
in addition to providing the appropriate macros and functions in
|
||
ffetarget. Note that if combinatorial explosion actually becomes a
|
||
problem for a given machine, one might have to modify the way conversion
|
||
expressions are built so that instead of just one conversion expr, a
|
||
series of conversion exprs are built to make a path from one type to
|
||
another that is not a "near neighbor". For now, however, with a handful
|
||
of each of the numeric types and only one character type, things appear
|
||
manageable.
|
||
|
||
A nonobvious change to ffetarget would be if the target machine was
|
||
not a 2's-complement machine. Any item with the word "magical" (case-
|
||
insensitive) in the FFE's source code (at least) indicates an assumption
|
||
that a 2's-complement machine is the target, and thus that there exists
|
||
a magnitude that can be represented as a negative number but not as
|
||
a positive number. It is possible that this situation can be dealt
|
||
with by changing only ffetarget, for example, on a 1's-complement
|
||
machine, perhaps #defineing ffetarget_constant_is_magical to simply
|
||
FALSE along with making the appropriate changes in ffetarget's number
|
||
parsing functions would be sufficient to effectively "comment out" code
|
||
in places like ffeexpr that do certain magical checks. But it is
|
||
possible there are other 2's-complement dependencies lurking in the
|
||
FFE (as possibly is true of any large program); if you find any, please
|
||
report them so we can replace them with dependencies on ffetarget
|
||
instead.
