* PR #1695: Fix time library build for Apple platformsGravatar Eduardo Menges Mattje2024-07-11
| | | | | | | | | | | | | | | Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1695 #1495 converted the `if (APPLE)` check for linking against `CoreFoundation` to generator expressions, which is fine and all. The issue is that they forgot the other Apple platforms, making builds for iOS impossible. This patch fixes this issue by adding the other Apple platforms that CMake support to the generator expression.

* Use _decimal_ literals for the CivilDay example.Gravatar Devin Jeanpierre2024-04-02
| | | | | | | Using `07` is a neat pun, but it not friendly to the reader. If the reader naively copies it and then changes the `7` to an `8` or a `9`, it will fail compilation: `invalid digit ... in octal constant`. Best avoided. Note that the other examples do not use octal literals. PiperOrigin-RevId: 621335289 Change-Id: I6b11a639c5ba675eb29467baf45996ceff0ed9bf

| | | | | | | | | | | | | | | | | | | | | | | | | | | | `time_internal::IDivDuration`, by splitting the slow path to a separate function. With that change, the compiler can inline the fast path. This is specially important in the context of `Duration::operator%=`, because it allows proving that the return value is unused, therefore avoiding expensive multiplies and divides (e.g. `*q = num_hi / den_hi;`). ``` name old cpu/op new cpu/op delta BM_Duration_Modulo 23.1ns ± 0% 22.5ns ± 0% -2.42% (p=0.000 n=20+16) BM_Duration_Modulo_FastPath 7.05ns ± 0% 4.85ns ± 0% -31.17% (p=0.000 n=20+20) name old time/op new time/op delta BM_Duration_Modulo 23.1ns ± 0% 22.6ns ± 0% -2.43% (p=0.000 n=20+16) BM_Duration_Modulo_FastPath 7.06ns ± 0% 4.86ns ± 0% -31.18% (p=0.000 n=20+20) name old INSTRUCTIONS/op new INSTRUCTIONS/op delta BM_Duration_Modulo 188 ± 0% 178 ± 0% -5.32% (p=0.000 n=20+20) BM_Duration_Modulo_FastPath 84.0 ± 0% 62.0 ± 0% -26.19% (p=0.000 n=20+20) name old CYCLES/op new CYCLES/op delta BM_Duration_Modulo 73.8 ± 0% 72.1 ± 0% -2.27% (p=0.000 n=19+20) BM_Duration_Modulo_FastPath 22.5 ± 0% 15.5 ± 0% -31.13% (p=0.000 n=19+20) ``` Note: We don't need to expose `absl::time_internal::IDivDuration` at all given that we have a public `absl::IDivDuration`.

* Decrease the precision of absl::Now in x86-64 debug buildsGravatar Fangrui Song2024-02-01
| | | | | | | | | | | | | | | | | | CycleClock::Now utilizes ABSL_INTERNAL_CYCLECLOCK_SHIFT to discourage reliance on the raw CPU cycle counter values. As a side effect, it discourages strictly-increasing assumption. Apply the idea to discourage over-reliance on the precision of absl::Now/absl::GetCurrentTimeNanos. Programs relying on a very high precision often exhibit portability issues on machines with a lower cycle counter precision, or worse, race conditions. For example, Apple M1 emulated x86 RDTSC only guarantees weakly-increasing RDTSC values. x86 clock speed is usually measured in GHz and is still precise after we drop 8 least significant bits.

* Bazel: Support layering_check and parse_headersGravatar Derek Mauro2023-10-10
| | | | | | | | | | | | | The layering_check feature ensures that rules that include a header explicitly depend on a rule that exports that header. Compiler support is required, and currently only Clang 16+ supports diagnoses layering_check failures. The parse_headers feature ensures headers are self-contained by compiling them with -fsyntax-only on supported compilers.
