gcc/rust/ChangeLog: * util/rust-intrinsic-values.h (Intrinsics): Add new entries for atomic binary op function names. * backend/rust-intrinsic-handlers.h (inner::atomic_binary_op): New function for compiling atomic binary op intrinsics. (atomic_xadd): New function to handle atomic_xadd and its variants. (atomic_xsub): New function to handle atomic_xsub and its variants. (atomic_and): New function to handle atomic_and and its variants. (atomic_nand): New function to handle atomic_nand and its variants. (atomic_or): New function to handle atomic_or and its variants. (atomic_xor): New function to handle atomic_xor and its variants. * backend/rust-intrinsic-handlers.cc (inner::atomic_store): Add new assert for return type. (inner::atomic_load): Likewise. (inner::atomic_binary_op): Implement. (atomic_xadd): Implement. (atomic_xsub): Implement. (atomic_and): Implement (atomic_nand): Implement. (atomic_or): Implement. (atomic_xor): Implement. * backend/rust-compile-intrinsic.cc (generic_intrinsics): Add entries for the new atomic binary op intrinsics. * typecheck/rust-hir-type-check-intrinsic.cc (intrinsic_rules): Likewise, but for type checking.
