From ad367d826e5959792ce7384be62ba1ccffbf0d9a Mon Sep 17 00:00:00 2001 From: hev <wangrui@loongson.cn> Date: Wed, 11 Oct 2023 10:24:18 +0800 Subject: [PATCH 1/7] [LoongArch] Improve codegen for atomic ops (#67391) This PR improves memory barriers generated by atomic operations. Memory barrier semantics of LL/SC: ``` LL: <memory-barrier> + <load-exclusive> SC: <store-conditional> + <memory-barrier> ``` Changes: * Remove unnecessary memory barriers before LL and between LL/SC. * Fix acquire semantics. (If the SC instruction is not executed, then the guarantee of acquiring semantics cannot be ensured. Therefore, an acquire barrier needs to be generated when memory ordering includes an acquire operation.)

An acquire barrier needs to be generated when memory ordering includes an acquire operation. This PR improves the codegen further by only handling the failure ordering.

Currently LoongArch uses an ll.[wd]/sc.[wd] loop for ATOMIC_CMP_XCHG. Because the comparison in the loop is full-width (i.e. the `bne` instruction), we must sign extend the input comparsion argument. Note that LoongArch ISA manual V1.1 has introduced compare-and-swap instructions. We would change the implementation (return `ANY_EXTEND`) when we support them.

I think it applies to LoongArch as LoongArch has a weak memory-model. But I'm not able to write a test to demonstrate this issue. Perhaps self-modifing code should be wrote?
