[Gm2] latest cvs changes

[Gaius Mulley]

Hi,

in the latest cvs are fixes to prevent memory leaks within the
DynamicStrings module and its dependents.  Much self checking code has
been added which can be configured at build time.  All regressions pass
on x86_64 Debian stable.

regards,
Gaius


here are the logs:

  * gm2/Make-lang.in:  compile static versions of
    DynamicStrings, FormatStrings, M2Quads, M2Options, M2Search
    with $(GM2_DEBUG_STRMEM) (-fcpp) flag to track down any
    memory leaks.
  * gm2/gm2-compiler/M2Options.mod:  changes to allow debugging
    code to be included if -fcpp is used.
  * gm2/gm2-compiler/M2Printf.mod:  changes to allow debugging
    code to be included if -fcpp is used.
  * gm2/gm2-compiler/M2Quads.mod:  changes to allow debugging
    code to be included if -fcpp is used.
  * gm2/gm2-compiler/M2Search.mod:  changes to allow debugging
    code to be included if -fcpp is used.
  * gm2/gm2-libs/DynamicStrings.def:  added definition for
    PopAllocationExemption.
  * gm2/gm2-libs/DynamicStrings.mod:  fixed memory leaks and
    bugs related to deallocating strings.
  * gm2/gm2-libs/FormatStrings.mod:  changes to allow debugging
    code to be included if -fcpp is used.  Also fixed memory
    leaks, which occurred if strings were not Mark'ed.
  * gm2/gm2-libs/FpuIO.mod:  tidied up header comment and added
    DynamicString debugging code.
  * gm2/gm2-libs/SEnvironment.mod:  tidied up header comment and
    added DynamicString debugging code.
  * gm2/gm2-libs/SFIO.mod:  tidied up header comment and
    added DynamicString debugging code.
  * gm2/gm2-libs/StringConvert.mod:  changes to allow debugging
    code to be included if -fcpp is used.  Also fixed memory
    leaks, which occurred if strings were not Mark'ed.

  * gm2/gm2-libs/FIO.mod:  removed unnecessary import of FIO.
  * gm2/gm2-libs/FormatStrings.mod:  included cpp macros for
    debugging memory leaks within the module.
  * gm2/gm2-libs/FpuIO.mod:  included cpp macros for
    debugging memory leaks within the module.
  * gm2/gm2-libs/SArgs.mod:  included cpp macros for
    debugging memory leaks within the module.
  * gm2/gm2-libs/SEnvironment.mod:  included cpp macros for
    debugging memory leaks within the module.
  * gm2/gm2-libs/StringConvert.mod:  included cpp macros for
    debugging memory leaks within the module.
  * gm2/gm2-libs-pim/RealConversions.mod:  included cpp macros for
    debugging memory leaks within the module.  Also fixed
    doPowerOfTen.

  * gm2/gm2-libs/DynamicStrings.mod:  writeAddress (New
    procedure),
    writeLongcard (New procedure),
    DumpStringSynopsis (New procedure).
  * gm2/gm2-libs-pim/RealConversions.mod:  import debugging
    versions of the DynamicString primitives and fix memory leak.
  * gm2/gm2-libs-pim/RealInOut.mod:  import debugging
    versions of the DynamicString primitives and fix memory leak.

  * gm2/gm2-libs/DynamicStrings.mod:  added forward declaration.
  * gm2/gm2-libs/DynamicStrings.mod:  corrected typo.
  * gm2/gm2-libs/DynamicStrings.mod:  fixed initialization order
    bug by using Init and a boolean.
  * gm2/gm2-libs/DynamicStrings.mod:  implemented the debugging
    print statements with write.
  * gm2/gm2-libs/StringConvert.mod:  fixed more memory leaks by
    Mark(ing) appropriate strings.
  * gm2/gm2-libs/DynamicStrings.mod:  reimplemented the frame
    data structure some of the key list routines.
  * gm2/gm2-libs/DynamicStrings.mod:  more minor fixes to aid
    p2c.
  * gm2/gm2-libs/DynamicStrings.mod:  minor fix moving data type
    declarations to satisfy p2c.
  * gm2/Make-lang.in:  added $(GM2_CPP) variable.
  * gm2/gccgm2.c:  removed incorrect comment boilerplate.
  * gm2/gm2-libs/DynamicStrings.def:  added debugging equivalents
    of InitString and family, Mult, Dup and Slice.  New procedures
    (PushAllocation) (PopAllocation).
  * gm2/gm2-libs/DynamicStrings.mod:  PoisonedOn FALSE.
  * Implemented
    debugging equivalents of InitString and family, Mult, Dup and
  * Slice.
    Also added memory leak verification
  * PushAllocation/PopAllocation.
  * gm2/gm2-libs/RTExceptions.mod:  New procedure (TidyUp) called
  * during
    finalisation to deallocate memory.
  * gm2/gm2-libs/StringConvert.mod:  fixed many memory leaks by
    Mark(ing) appropriate strings.
  * gm2/gm2-libs-pim/RealConversions.mod:  fixed many memory leaks
  * by Mark(ing) appropriate strings.
