[Bug target/62253] gcc incorrectly mixes direct atomic instructions with calls to atomic library
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=62253 --- Comment #1 from Andrew Pinski --- Iirc lib atomic on x86 uses the atomic instructions for 32bit and not the pthread implemention. Also if you have xchng, you can do all functions using that one without using the pthread implemention.
