Metrowerks 68K Linker Release Notes

Bugs Fixed in This Version

• Fixed a bug where <Project Name>.seg files would not work correctly.
• Fixed a bug where when the linker would write the default <project name>.exp file, if the project's name was longer than 27 characters, the link would fail with a cryptic message.
• Fixed a bug in the CFM68K linker where flat pef data fork based applications would crash under System 7.5.5 or greater when the CFM68K enabler is not installed.

Metrowerks PPC Linker Release Notes

Bugs Fixed in This Version

• Fixed a bug where the linker would complain about multiply defined TOC entries when linking against Apple MrC xcoff libraries.
• Fixed a bug where when the linker would write the default <project name>.exp file, if the project's name was longer than 27 characters, the link would fail with a cryptic message.

Metrowerks PPC Release Notes

New Features in This Version

• Added new intrinsic functions:

float __fabsf(float);
float __fnabsf(float);

These will generate more efficient code than __fabs() and __fnabs() when using 'float' variables.

Bugs Fixed in This Version

• Fixed a bug with long long shifting left/right not setting the correct bits.
• 'long long' struct members misaligned under PowerPC alignment CW11 had a bug wherein 'long long' struct members were aligned to 2-byte boundaries. It now properly aligns them to 4-byte boundaries.

*** ANY EXISTING CODE THAT USES 'long long' MUST BE RECOMPILED ***

• 'long long' arguments do not work with varargs routines.
  The calling convention used for 'long long' in CW11 was incompatible with the varargs implementation. It has been changed so that varargs work properly, and is now compatible woth Apple's proposed ABI.

*** ANY EXISTING CODE THAT USES 'long long' MUST BE RECOMPILED ***

• Destructors sometimes called twice for the same local object
  There was a bug in exception table generation for certain kinds of source sequences.
• Crash when throwing Exception if Global Optimization was enabled
  Fixed a bad bug wherein local variables needing destruction may be incorrectly optimized away, causing unpredictable crashes if an exception was thrown.
• Internal Compiler Error when using 'long long' in a switch()
• Incorrect code generated for long longs and -= operator
• Level 3/4 Optimization erroneously deletes loop counters
  In certain loops that look something like this:

  for (i = k1; i < n; i++)
  S1;
  while (i--)
  S2;

  the optimizer would inadvertantly delete the increment of 'i' in the first loop.

Metrowerks 68K Release Notes

New Features in This Version

• Support for a new (non-SANE/non-881) flaoting point runtime model

  #pragma fp_library on|off|reset (default off)

  This model emulates IEEE floating points in software:

  • 32-bit (single): float
  • 64-bit (double): short double, double, long double

  You have to include the runtime library "fp68k.lib" to use this model.

  #pragma fp_pilot_traps on|off|reset (default off)

  This #pragma will use the pilot system traps instead of the "fp68k.lib" library. This option can only be used on the Pilot.

Metrowerks C/C++ Compiler Release Notes

New Features in This Version

• Support for the Objective C #import preprocessor directive This also works for ANSI C and C++ unless ANSI strict is enabled.
• The inlining is now more selective at the 3rd and 4th levels to avoid excessive code bloat and compile times. Most noticeable with MSL C++.
• Added support for long long constants defined using 'll' or 'LL'. These constants may also be defined as being unsigned, by using a 'u' or 'U' prefix.

Bugs Fixed in This Version

• The compiler gives an error message when you try to use dynamic_cast for a SOM class pointer or reference.
• "<bool> op= <expr>" expressions are now supported.
• huge 64-bit integral constants (bit 63 set) are now treated as unsigned.
• fixes a bug with statement level '&&' and '||' expressions.
• fixes a bug in the vtable (virtual function dispatch table) slot allocation in classes with overloaded virtual functions. vtable slots were not allocated in lexical order when newly introduced overloaded functions were not declared as a block. This bug was introduced in CW9.

  class foo {
  virtual void f();
  virtual void g();
  virtual void f(int);
  };

  CW9-CW11 would allocate the vtable slots in non-lexical order:

  foo::f()
  foo::f(int)
  foo::g()

  now the compiler will use the correct order:

  foo::f()
  foo::g()
  foo::f(int)

  you can still get the old ordering by using "#pragma old_vtable on"

  #pragma old_vtable on|off|reset (default off)

  if you have to link with a C++ library that was generated by CW9-11.

• Fixed a bug with comparisons against 0.0 and inlining.

27 Mars 1997 : MSL 2.1.1

Metrowerks Standard C Library Release Notes

New Features in This Version

Note that, in order to use long long support, __MSL_LONGLONG_SUPPORT__ must be defined when the MSL C library is built as well as when the application is built.

Bugs Fixed in This Version

• limits.h has been modified so that limits.be.h is not #included unless __dest_os == __be_os.
• \r in output to the console now causes a non-destructive carriage return.
• \b in output to the console now causes a non-destructive backspace.
• #pragma options align=native

  #if defined(__CFM68K__) && !defined(__USING_STATIC_LIBS__)
#pragma import on
#endif
/*...*/
#if defined(__CFM68K__) && !defined(__USING_STATIC_LIBS__)
#pragma import reset
#endif

  has been added to all source files.

• math.h and fp.h (in Universal headers) have been modified so that they can both be #included without syntax errors.
• sscanf() now works correctly with a null source string.
• printf() modified so that a sign appears in the correct position when left zero-fill is specified.
• printf() now prints -Inf for negative infinite values.

Metrowerks' Standard C++ Library Release Notes

Getting the New C++ Draft

Copies of the Committee draft are now available for downloading at: <http://www.setech.com/x3.html>, <http://www.maths.warwick.ac.uk/c++/pub/>

New Features in This Version

• long long support for the basic_istream operator>> and the basic_ostream operator<<. Note that, in order to use this support, __MSL_LONGLONG_SUPPORT__ must be defined when the MSL C++ library is built ans well as when the application is built.
• PPC shared library support
• MSL Build App, an application that builds the proper MSL libraries for a given configuration

Bug Fixes since MSL C++ 2.1

• tree::buffer_size() now calls allocator.init_page_size(). A new member function, init_page_size_small() has been added in the allocator class. This will allocate a buffer 1/4 the size of the default ammount.
• Static destructors with iostream objects were not being flushed.

  #include <iostream.h>
  class foo{
  public:
  foo() { cout << "foo::foo()\n"; }
  ~foo() { cout << "destructor\n"; }
  };
  
  static foo f;
  
  int main() { return 0;
  };

  ~foo was not being called. This is now fixed.

• The statement cin >> int_var; was failing when the value 0 was entered. The failbit in cin was being set, preventing any further input from cin. This is now fixed.
• #pragma options align=native

  #if defined(__CFM68K__) && !defined(__USING_STATIC_LIBS__)
  #pragma import on
  #endif
  /*...*/
  #if defined(__CFM68K__) && !defined(__USING_STATIC_LIBS__)
  #pragma import reset
  #endif

  has been added to all source files.

• Initial whitespace is now skipped in operator>> basic_string and basic_string.getline().
• Corrections to putback() for bufferless files.
• Corrections to list::~list() for proper destruction
• Additional iterator_trait specializations for all basic types
• Remove const_pointer allocator<T>::address (const_reference x) to resolve ambiguous access errors for list<int*>, vector<int*>
• Fixed reverse_iterator::operator+,-,+=,-= defined out of line so that reverse_iterator can be instantiated for non random-access iterators
• stable_sort codegen less inlinded due to new compilers

Outstanding Bugs

• rb_tree::key () function in rb_tree::insert () does not work correctly.
• locale::id::id_ not initialized properly
