C Compiler ECO Availability?

» close window

The Question is:

We would like to get patches for DEC C v5.6. Unfortunatelly we did not manage
 find any patches for this version of DEC C. The closest patches we found
 relate to DEC C v5.7. Our question: are there patches for v5.6 or may we
 implement patches related to v5
..7 for v5.6? Is there a possibility to get somehow (download)totally new
 version (say 5.7 or 6.0) without changing our license or is it coupled with
 the necessity to acqiure some new licence?

The Answer is :

  V5.6 is quite old, and has a number of limitations.  Please upgrade.
  One of the salient changes was to the underlying code generator.  C
  compilers prior to V6.0 include a code generator which can potentially
  generate code that is not compliant with the Alpha architecture; code
  can be generated that cannot correctly execute on Alpha EV6 and later
  Alpha microprocessors.
  C compiler kits and C ECO kits are not normally made available for
  (unrestricted) download, as these are usually complete distribution
  kits.  When C ECO kits are available, these kits can generally be
  downloaded by contract support customers.  There is no ECO kit for
  the aforemented compiler code generation problem; a compiler version
  upgrade is required.
