Robert Clausecker 521c1fe0e2 libc/aarch64: fix strlen() when flush-to-zero is set ... Our SIMD-enhanced strlen() implementation for AArch64 uses a floating-point comparison to compare a bit mask to zero. This works fine under normal circumstances, but fails if the FZ (flush-to-zero) flag is set in FPCR (the floating-point control register) as then the CPU no longer distinguishes denormals from zero. This was not caught during testing; this flag is rarely set and programs that do so rarely perform string manipulation. Avoid this problem by using an integer comparison instead. The performance impact seems to be small (about 0.5 %) on the Windows 2023 Dev Kit, but seems to be more significant (up to around 19%) on the RPi 5.
