PiperOrigin-RevId: 293160245 -- 64439365e2b4a0b5e51ae0a7dafdb15912402dfd by Shahriar Rouf <nafi@google.com>: Add benchmarks for string_view: BM_CompareFirstOneLess and BM_CompareSecondOneLess. PiperOrigin-RevId: 293031676 -- b273b420cab24a6e3f487430987e09f4eb1caec4 by Greg Falcon <gfalcon@google.com>: Remove an unreachable line from charconv.cc. Fixes github issue #613. PiperOrigin-RevId: 292980167 -- 70babb5f7a3d9fdd00a2b3085c3c2b9fe0265c79 by Gennadiy Rozental <rogeeff@google.com>: Move GetFlag implementation into FlagImpl. This change will allow us to hide details of GetFlag overloads inside implementation detais. Eventually we'll migrate to a different implementation. No semantic changes in this CL. PiperOrigin-RevId: 292930847 -- 94bee7b7cc31e0167ee4b953281c1e78c96a574a by Abseil Team <absl-team@google.com>: Clarification in absl::Exponential documentation.

Only mark AtomicHook as constant-initializable on platforms where it is actually constant-initializable.

Example code: string_view1 demonstrates the problem, string_view2 DTRT. === string_view1 struct string_view1 { string_view1(const char* ptr, size_t n) : ptr(ptr), n(n) {} string_view1(const std::string& s) : ptr(s.data()), n(s.length()) {} const char* ptr; size_t n; }; struct S1 { S1(const std::string& s); string_view1 sv; }; S1::S1(const std::string& s) : sv(s) {} S1::S1 test byte ptr [rsi], 1 je .LBB0_1 mov rax, qword ptr [rsi + 16] mov qword ptr [rdi], rax movzx eax, byte ptr [rsi] test al, 1 jne .LBB0_5 .LBB0_4: shr rax mov qword ptr [rdi + 8], rax ret .LBB0_1: lea rax, [rsi + 1] mov qword ptr [rdi], rax movzx eax, byte ptr [rsi] test al, 1 je .LBB0_4 .LBB0_5: mov rax, qword ptr [rsi + 8] mov qword ptr [rdi + 8], rax ret === string_view2 struct string_view2 { string_view2(const char* ptr, size_t n) : ptr(ptr), n(n) {} string_view2(const std::string& s) : string_view2(s.data(), s.size()) {} const char* ptr; size_t n; }; struct S2 { S2(const std::string& s); string_view2 sv; }; S2::S2(const std::string& s) : sv(s) {} S2::S2 movzx eax, byte ptr [rsi] test al, 1 je .LBB1_1 mov rax, qword ptr [rsi + 8] mov rsi, qword ptr [rsi + 16] mov qword ptr [rdi], rsi mov qword ptr [rdi + 8], rax ret .LBB1_1: add rsi, 1 shr rax mov qword ptr [rdi], rsi mov qword ptr [rdi + 8], rax ret PiperOrigin-RevId: 272096771 GitOrigin-RevId: 406622c43f296eeedf00e0e9246acfb4ea6ecd5e Change-Id: I70173a2db68cd9b597fff1c09e00198c632cfe95
