  "message": "[flang-rt] Avoid libstdc++ guard symbols in RTNAME(Timef) (#195984)\n\nThe function-local `static Lock timef_lock;` introduced by PR #185377\nrequired thread-safe-static initialization, which causes the compiler to\nemit calls to `__cxa_guard_acquire`/`__cxa_guard_release` from\nlibsupc++/libc++abi -- a C++ runtime library dependency that flang-rt\nexplicitly avoids (see comment in\nflang-rt/include/flang-rt/runtime/lock.h).\n\nMove `timef_lock` to namespace scope, matching the existing\n`rand_seed_lock` pattern in the same file. The other function-local\nstatics (`start`, `ticks_per_sec`, `isInit`) have constant initializers\nand are unaffected.\n\nAssisted-by: AI",
