- Changes for 1.2.0 (16th May, 2000)
-
- * Added memory allocation profiling, which behaves in a similar way to mprof.
-
- * Added the PROF, PROFFILE, AUTOSAVE, SMALLBOUND, MEDIUMBOUND and LARGEBOUND
- options for memory allocation profiling purposes.
-
- * Added a new command for displaying tables from memory allocation profiling
- output files.
-
- * The -P and -p options to the mpatrol command are now called -X and -x.
-
- * The memleak tool is now called mleak.
-
- * The CHECK* options now display the calling function details even when the
- LOG* options are not used.
-
- * Added the ALLOWOFLOW option for allowing memory operations which overflow
- allocation boundaries to continue rather than being ignored.
-
- * The log file and profiling output file can now contain %p in their names
- which will be expanded to the name of the executable program file.
-
- * AIX and IRIX are now supported.
-
- * The recalloc() and cfree() functions now take extra arguments to be in line
- with the IRIX malloc library.

-
- * Fixed a bug in the reimplementation of memcmp() and bcmp() which used plain
- chars for comparison rather than unsigned chars.
-
- * Function call stack traversal is now more robust on UNIX systems, with
- the library simply stopping reading a call stack if it is corrupt rather
- than crashing.

- library for mpatrol.
-
- * Added a GDB command file for use with mpatrol.

- when using GCC.
-
- * A build script is provided for AmigaOS Aminet distributions.
-
- * malloc() and related memory allocation functions are now overridden without

- * Limited forms of brk() and sbrk() are now provided on certain non-UNIX
- platforms that do not have them.
-
- * The Windows version of mpatrol now allocates memory from the system in 64K

- efficiency of library execution and cause less memory fragmentation.

- * Added a default low-memory handler for C++ operators new and new[].
-
- * Added special name mangling for the GNU C++ operators.
-
- * Fixed a bug which occurred when allocating lots of pages using sbrk().
-
-
- Changes for 1.1.1 (9th March, 2000)
-
- * Added a section on threads to the mpatrol manual.
-
- * Added the USEDEBUG option for displaying filenames and line numbers in call
- stacks if the executable file contains debugging information.
-
- * Changed the definitions of the C++ operators so that they now include source
- level information.
-
- * Added the MP_NOCPLUSPLUS preprocessor macro for disabling C++ support in
- mpatrol.h.
-
- * The mpatrol.h header file should have less incompatibilities with the
- library functions that it overrides.
-
- * The prologue and epilogue functions are now only called for user allocations
- and not internal mpatrol allocations.

- was being wrongly assumed to be a Microsoft Word document.

-
- * Added the expand() function for backwards compatibility with other C
- libraries.
-
- * Added the LOGMEMORY option to log all calls to memory operation functions.

-
- * Added the utilities and library functions sections and documented the pkg

-
-

-
-

- ASCII, GNU Info, AmigaGuide and HTML format, and printed manuals in DVI,
- Postscript and PDF format.
-

- system heap, which might be useful on embedded systems which have no heap.

-
- * Added the CHECK option.
-

-
-
