1 OMG INTERFACE DEFINITION LANGUAGE COMPILER FRONT END: KNOWN PROBLEMS
2 -==================================================================-
6 This file describes what configurations are known to work correctly with
7 this release, and what are the known problems with this release as shipped.
8 Comments about future possible enhancements do not imply a commitment on
9 the part of Sun or any of its subsidiaries to produce these enhancements.
13 This release has been tested and is known to operate correctly on:
15 - Sparcstation 2 running SunOS 4.1.2, when compiled with SparcWorks 3.0
16 - Sparcstation 10 running Solaris 2.3, when compiled with SparcWorks 3.0.1
17 - Sparcstation 10 running Solaris 2.3, when compiled with SparcWorks 4.0
19 We are aware of a bug in GNU C++ (the latest version we tested was 2.5)
20 which causes up-casting (changing the type of an instance from a base class
21 to a more derived class, also known as "narrowing") to fail or cause a
26 This is a list of known problems with the current version of the CFE:
28 - The following syntax, although legal, is not accepted by the CFE:
30 .. sequence <string <10>> ..
32 This causes a parse error. The cause of this problem is that the '>>' is
33 read as a right shif operater and not as two '>'s. You can avoid this
34 problem by instead writing
36 .. sequence <string <10> > ..
38 - The following syntax, although legal, is not accepted by the CFE:
40 const string foo = "abc" " and" " another" " string";
44 const string foo = "abc and another string";
46 - The printout produced by the -d option for dumping the AST is not always
47 perfect. Specifically, dumping of sequences and arrays is deficient.
49 POSSIBLE FUTURE ENHANCEMENTS:
51 This is a list of areas in which the code of the CFE may change in future
54 - The current release is restricted in its use of C++ because it must
55 be possible to compile it using C++ 2.1. However, we have also provided
56 files that depend on features which are only present in C++ 3.0, such as
57 templates. If your compiler supports templates and you wish to use them,
58 copy the files in include/utl_tmpl to include, and copy the files in
59 util/utl_tmpl to util. You will also need to make compiler dependent
60 modifications to Makefiles throughout the CFE directory hierarchy to
61 enable the use of templates.
63 The code using templates was donated by Steve Vinoski of HP.
65 In a future release of the CFE only the template code may be included,
66 and hence users will need to use a C++ 3.0 or higher compiler.
68 - The UTL_list classes defined in the util directory are rudimentary. More
69 features may be added to make the functionality richer.
71 - The UTL_String class may be rewritten or replaced by a standard ANSI C++
72 String implementation. Applications will be shielded from this change.
