CORE for the core's general use.

TOOL for the tool to use (and the only one it uses).
|
|
SYMTAB for Valgrind's symbol table storage.
|
|
CLIENT for the client's mallocs/frees, if the tool replaces glibc's
|
|
malloc() et al -- redzone size is chosen by the tool.
|
|
DEMANGLE for the C++ demangler.
|
|
EXECTXT for storing ExeContexts.
|
|
ERRORS for storing CoreErrors.
|
|
|
|
When adding a new arena, remember also to add it to ensure_mm_init().
