// TARGET_BACKEND: NATIVE
// FILECHECK_STAGE: RemoveRedundantSafepoints

// This test checks:
// - there is only one safepoint per function
// - safepoint function is inlined in OPT mode, unless SMALLBINARY is needed (for ex, watchos_arm32)
// Might fail under -Xbinary=gc=stwms and -Xbinary=gc=noop. In this case, just add ignore clause.
