Replace std::to_string for integers with optimized version The std::to_chars functions from C++17 can be used to implement std::to_string with much better performance than calling snprintf. Only the __detail::__to_chars_len and __detail::__to_chars_10 functions are needed for to_string, because it always outputs base 10 representations. The return type of __detail::__to_chars_10 should not be declared before C++17, so the function body is extracted into a new function that can be reused by to_string and __detail::__to_chars_10. The existing tests for to_chars rely on to_string to check for correct answers. Now that they use the same code that doesn't actually ensure correctness, so add new tests for std::to_string that compare against printf output. * include/Makefile.am: Add new <bits/charconv.h> header. * include/Makefile.in: Regenerate. * include/bits/basic_string.h (to_string(int), to_string(unsigned)) (to_string(long), to_string(unsigned long), to_string(long long)) (to_string(unsigned long long)): Rewrite to use __to_chars_10_impl. * include/bits/charconv.h: New header.

libstdc++: Value-initialize std::atomic for C++20 (P0883R2) This implements the new requirements for C++20 that std::atomic should initialize the atomic variable in its default constructor. This patch does not add the deprecated attribute to atomic_init, but that should be done at some point as it's deprecated in C++20. The paper also deprecates the ATOMIC_FLAG_INIT macro, although we can't apply the deprecated attribute to a macro.

Implement C++20 operator<=>. There are three major pieces to this support: scalar operator<=>, synthesis of comparison operators, and rewritten/reversed overload resolution (e.g. a < b becomes 0 > b <=> a). Unlike other defaulted functions, where we use synthesized_method_walk to semi-simulate what the definition of the function will be like, this patch determines the characteristics of a comparison operator by trying to define it. My handling of non-dependent rewritten operators in templates can still use some work: build_min_non_dep_op_overload can't understand the rewrites and crashes, so I'm avoiding it for now by clearing *overload. This means we'll do name lookup again at instantiation time, which can incorrectly mean a different result. I'll poke at this more in stage 3. I'm leaving out a fourth section ("strong structural equality") even though I've implemented it, because it seems likely to change radically tomorrow. Thanks to Tim van Deurzen and Jakub for implementing lexing of the <=> operator, and Jonathan for the initial <compare> header. gcc/cp/ * cp-tree.h (struct lang_decl_fn): Add maybe_deleted bitfield.
