/* Allocation arenas.
|
|

|
CORE for the core's general use.
|
|
TOOL for the tool to use (and the only one it uses).
|
|
DINFO for debug info (symbols, line #s, CFI, etc) 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.
|
|
TTAUX for storing TT/TC auxiliary structures (address range
|
|
equivalence classes).
|
|
|
|
When adding a new arena, remember also to add it to ensure_mm_init().
