Bug ID: 105262
Summary: Consider adding
std::__new_allocator::allocate(size_type, nothrow_t)
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
Target Milestone: ---
It would be useful to be able to use std::__new_allocator as an abstraction for
the nothrow versions of operator new. That way all the logic for choosing
whether to use aligned new/delete and whether __builtin_operator_new is
available would only be in one place.
It could be used in std::basic_stacktrace::_Impl::_M_allocate and in
std::get_temporary_buffer.
N.B. I proposed this in
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0401r0.html#Nothrow.overload.of.allocate..
