Kuck & Associates, Inc. KAI C++ Compiler (KCC) Version 3.4f -- November 3, 1999 System requirements for SGI Irix 6.x version: OS: Irix 6.2, 6.4, or 6.5 Software: SGI C compiler disk: 40 Mb installed General Description: KAI C++ is an optimizing compiler for production C++ applications. It focuses on optimizations that allow you to use object-oriented design throughout your application. You get both the performance of C and the productivity of objects. See http://www.kai.com/C_plus_plus/index.html for a more complete product description. Compilation process: The top level KAI C++ driver, KCC, is intended to be used as a compiler. Under the top level driver there are three distinct compilation phases. First, the front- end parses the source file, performs high-level optimiza- tions, and generates an intermediate file in standard C. Next, a C compiler reads in the intermediate C file and generates an object file. Last of all, a link process combines the object modules and libraries, and takes care of template instantiation and static object initialization. Compatibility: KAI C++ is link-compatible with SGI's C compilers, but not link-compatible with any other C++ compiler. Attempting to link code compiled by KCC and another C++ compiler will probably result in link-time failures or run-time faults. This means that you must compile all of your C++ code and C++ libraries with KAI C++. KAI C++ 3.4 includes a very close to standard C++ library, including I/O and STL. The C++ standard differs from existing practice in some ways. We strongly recommend reading the migra- tion document http://www.kai.com/C_plus_plus/migrate/index.html for a summary of differences that affect existing codes. The KAI C++ Debugger (kdb) is available for download from KAI as a separate package. The TotalView Debugger is also available from Etnus, Inc. with support for KAI C++ on SGI/Irix. See http://www.etnus.com for more information. See our web page http://www.kai.com for the latest news on this and other Kuck & Associates products. Changes in version 3.4f: - Fix for bug ID [98I13].

KAI C++ for Linux is also available under FlexLM licensing, but continues to be available under a Personal Use License (which uses the KCC_LICENSE environment variable). KAI C++ for other platforms continues to use the same license manager as in KAI C++ 3.3. - Because it is a major release and due to changes in license managers, KAI C++ 3.4 will require new license codekeys on all platforms. KAI C++ 3.3 license codekeys will not allow you to operate KAI C++ 3.4. To purchase KAI C++ 3.4 license codekeys or receive KAI C++ 3.4 license codekeys under an active support contract, contact KAI at c++support@kai.com. Be sure to include any previous license codekey(s) along with the name of the person to whom the codekey was issued and/or the name of the company to which the codekey was issued.

Be sure to browse through the new tutorial on multi-threaded C++ (included in the KAI C++ User Guide). - Changes to include files for support of thread-safety. - Reduction in size of libKCC.a due to file reorganization. - Small number of minor bug fixes. Changes in Version 3.3c: - Fixed inlining problem which could lead to code bloat. - Fixed problems with compiling two tests in the Blitz++ testsuite. - Fixed problem with compiling example code in guiding declarations section of User Guide. - Fixed problem with parameters of the form "typename ABC::template DEF" in class template member functions. - Fixed problem with virtual inline function in a base class [G19S]. - Fixed problem with basic_stringbuf<>::str(). - Fixed problem which lead to "internal error: lower_type: bad kind". - Fixed problem which occured at higher optimization level(s) and generated assertion failure at "kfront/def-use/NBitLatticeBase.C, line 62". - Fixed problem in which required that certain operators be defined for qc in order to declare a queue. Fixed similar problem in certain other container classes. Changes in Version 3.3b: - Fix for vector::erase() when erasing empty vector. Similar fix for a few other containers. - Link-compatibility error no longer issued when mixing .o's compiled in C mode with those compiled in C++ mode with exception handling. - Fix to prelinker so it doesn't loop when presented with a non-existent library name. - ti_files directory only created when needed. Changes in Version 3.3a: - Object files and libraries produced by KCC version 3.3 are not link-compatible with those produced by KCC 3.2 or earlier. Every component of an application must be recompiled. - Exceptions are now enabled by default. - Implicit inclusion is now turned off by default. - Keyword template is now required when referring to member template typenames. - Function getline in no longer counts characters. - Template class valarray no longer has implicit conversions to T* and const T*. - The option --split (used on 3.2 when building archive libraries) is replaced by the option --one_instantiation_per_object used to build .o files. - Adding or replacing files in an archive library is now deimplemented. ``KCC -o libX.a x1.o'' now removes libX.a and builds a new one containing only x1.o. - KCC 3.3's runtime library is now supplied as both a shared object library and as a traditional archive library. Most linkers default to choosing the shared object version, which can require extra care so that it travels with the application when it is shipped to another host. - Please see the KAI C++ User Guide for additional information on these changes. Changes in Version 3.2d: - Fixed kfront problem where library builds involving a large number of files would lead to errors such as "ar: bad address" that was introduced in 3.2c. - Fixed problem with compiling code generated by ksplit. - Removed memory leak from Expr::destroy_tree. - Applied various other patchs to kfront. Changes in Version 3.2c: - Two new inlining controls that assist in performance vs. code bloat problems. See doc/UserGuide/chapter_3.html#inlining . - Default for conditional inclusion is same as for vendor's C++. E.g., ``X Open'' environment is included by default. This is a reversion to the behavior of Version 3.2a by popular demand. - KCC now removes a shared library before trying to build one. Previous versions tried to add new functions to existing shared library. - operator *= for complex fixed to use proper precision instead of float. - Numerous other fixes for parser and headers - now works even when --no_array_new_and_delete is requested. - __signed__ now recognized for Linux. Changes in Version 3.2b: - Default for conditional inclusion is strict ANSI. - Fixed digits10 for instances of class std::numeric_limits for integral types. - Reduced code bloat from excessive use of inline keyword in class std::basic_ostream. - Fixed bug in which no-op virtual functions were being removed. Changes in Version 3.2: - The library is much closer to the December 1996 draft, and now compiles in --strict mode. Namespace rel_ops, Iterator traits, and allocators for standard container classes are implemented. Class char_traits replaces ios_traits and string_char_traits. See Section 9.12 of UserGuide for details. - Class bitset is much faster and takes much less space. - Classes set, multiset, map, and multimap compile faster and generate much more compact code. - The non-standard header has been added for compatibility with other C++ implementations. - Partial specialization of class templates and partial ordering of function templates are both implemented. See Sections 9.2.9 and 9.2.10 of UserGuide for details. - Reflecting recent changes in the draft, guiding declarations are no longer enabled in --strict mode. See Section 9.2.11 of UserGuide for details. - Covariant return types for virtual functions are implemented. See Section 9.6.6 of UserGuide for details. - Constant folding for some real and complex functions. See Section 3.2.5 of UserGuide for details. - The option ``--parallel_build '' causes KCC to do compiles and prelinking recompiles in parallel with up to n processes. See Section 5.5.3 of UserGuide and man page entry for more details. - The option ``--component_time'' causes KCC to summarize where the compilation time went' See the man page entry for more details. Changes in Version 3.1: - Precompiled header feature - Now supports long-double arithmetic on 64-bit machines. - Debugging support improved for dbx. - Incomplete types in exception specifications now reported as error as per recent ANSI draft. - generates faster code. - Many fixes to standard library. Changes in Version 3.0g: - Problems with writing and converting the character 0xFF fixed. - Bug related to ambiguity in ANSI working paper. Methods istream::get() and istream::read now set eofbit and failbit when they reach end-of-file. - For 32-bit SGI platforms, line-number debug info is no longer lost at +K0. - Core dump of KCC at +K2 and +K3 fixed. - Incorrect optimization of widening casts on arithmetic operations fixed. - Comparison of iterator and const_iterator allowed for map, deque, and list. - correctly declares argument_type in binder1st and binder2nd. - Warnings in and fixed. - Operators new[] and delete[] are now much faster when large numbers of arrays are allocated.
