9 * We implement the default operators new/delete as part of
10 * libmozalloc, replacing their definitions in libstdc++. The
11 * operator new* definitions in libmozalloc will never return a NULL
12 * pointer.
13 *
14 * Each operator new immediately below returns a pointer to memory
15 * that can be delete'd by any of
16 *
17 * (1) the matching infallible operator delete immediately below
18 * (2) the matching system |operator delete(void*, std::nothrow)|
19 * (3) the matching system |operator delete(void*) noexcept(false)|
20 *
21 * NB: these are declared |noexcept(false)|, though they will never
22 * throw that exception. This declaration is consistent with the rule
23 * that |::operator new() noexcept(false)| will never return NULL.
24 *
25 * NB: mozilla::fallible can be used instead of std::nothrow.
