-Subject: [PATCH] checks.m4: Keep the atomic test program from being optimized
- away
-
-TORRENT_CHECK_ATOMIC decides whether -latomic is needed by linking a
-program that loads from a local std::atomic<uint64_t>. The atomic never
-escapes, so with -O2 in CXXFLAGS clang folds the load to a constant and
-no __atomic_* call is emitted. The check then reports that -latomic is
-not required even on targets that need it for 64-bit atomics, such as
-riscv32, and linking fails later:
-
-  ld.lld: error: undefined symbol: __atomic_load_8
-
-Make the atomic global and modify it with fetch_add() so the atomic
-operations are emitted at any optimization level.
-
