Power Architecture targets

• V4.2c
  The constant replacement optimization has been enhanced.
• V4.2b
  Improved usage of bit instructions
• V4.2a
  Introduction of BIT variables. Linker can suppress uncalled functions.

• V4.6.1
  Adds support for S08 derivatives with more than 64K of on-chip FLASH memory including the HCS08QE128.

  Version number format changed to MS Windows compatible version format
• V4.5c
  The compiler allows @inline functions with return values.
• V4.5b and V4.5a
  Introduced factorization optimization (optional) that produces more compact but slower code. The parameters passing scheme has changed for some special cases.
• V4.4g
  The constant replacement optimization has been enhanced. Improved code generation on some non-reentrant function parameter passing.
• V4.4f
  The optimizer has been enhance for a better merging of identical instructions.

  Maintenance release
• V4.7.10
  Maintenance release
• V4.7.9
  Maintenance release
• V4.7.8
  Maintenance release
• V4.7.7
  The compiler implements a unified representation of far addresses. Far pointer variables are using a pointer display with logical address first followed by the page value, while long integer variables are using a linear high to low display compatible with standard 32 bits operations.
  
• V4.7.6
  Maintenance release
• V4.7.5
  The parser was producing a PANIC error message when calling a far function by a pointer to a near function cast into a pointer to a far function.
• V4.7.4
  The compiler adds support for HCS12B family.
  The compiler optimizes the allocation of local variables by sharing at the same location for variables which are not used together.
  The constant propagation optimization has been enhanced for initialized declarations of local variables.
  @far pointers to const objects are no longer accessing these objects via the ppage register by default. Explicit accesses using ppage is enabled by using the @ppage modifier.
  The linker has been enhanced to propagate an alignment request with option -r to all the modules of the segment and not only to the segment start address.
