The new allocator is in the stdc++. Look for the file in GCC source:


for an example of new. It uses malloc to get the memory and malloc is part of the 
libcsupport section of RTEMS.

The code as a link can be view online here:

It is in libstdc++.a. For a Coldfire I can do:

  $ m68k-rtems-nm --demangle `m68k-rtems-gcc -print-file-name=libstdc++.a` | grep new

and get a list of the various new operators in the library.

Standard allocators are provided in stdc++ and using g++ to link will automatically 
link in stdc++.
