Subject: [PATCH 0/19][GCC-8] aarch64: Backport outline atomics
Hi,
This series backports all the patches and fixes regarding outline
atomics to the gcc-8 branch.
Bootstrapped the series for aarch64-linux-gnu and regression tested.
Is this OK for gcc-8?
Andre Vieira (19):
aarch64: Add early clobber for aarch64_store_exclusive
aarch64: Simplify LSE cas generation
aarch64: Improve cas generation
aarch64: Improve swp generation
aarch64: Improve atomic-op lse generation
aarch64: Remove early clobber from ATOMIC_LDOP scratch
aarch64: Extend %R for integer registers
aarch64: Implement TImode compare-and-swap
aarch64: Tidy aarch64_split_compare_and_swap
aarch64: Add out-of-line functions for LSE atomics
Add visibility to libfunc constructors
aarch64: Implement -moutline-atomics
Aarch64: Fix shrinkwrapping interactions with atomics (PR92692)
aarch64: Fix store-exclusive in load-operate LSE helpers
aarch64: Configure for sys/auxv.h in libgcc for lse-init.c
aarch64: Fix up aarch64_compare_and_swaphi pattern [PR94368]
aarch64: Fix bootstrap with old binutils [PR93053]
Thanks for putting these together.
Before they can go in we need to get this fix for PR93053 into GCC 9.
Can you please test it on that branch to help Jakub out?
Thanks,
Kyrill
Bootstrapped and regression tested the PR93053 fix from Jakub on gcc-9
branch and it looks good.
