Remove data dependencies On the ARMv7-A platform, NEON instructions usually take more cycles than ARM instructions. To reduce instruction latency, it’s better to avoid using the destination register of current instruction as the source register of next instruction.

Witryna4 sie 2016 · I also thought of mapping the 3 fence intrinsics to __sync_synchronize() (full memory barrier), ... Since AArch64 has load-acquire and store-release instructions, you can get more efficient code from using those instead of plain loads and separate store-barriers. ... Improving the copy in the close modal and post notices - 2024 edition.
WitrynaAccording to my understanding, the __load_acquire intrinsic emits either the ldar or ldapr instructions (according to criteria that are beyond my cat-sized brain 🐱 🧠), while the __stlr intrinsic emits the stlr instruction. These are significantly more efficient than what was previously possible. Currently, MSVC's STL is using its classic (slower) codepaths for …
