◆ findStoresToUninstrumentedArgAllocas()

void findStoresToUninstrumentedArgAllocas ( AddressSanitizer & ASan,
Instruction & InsBefore,
SmallVectorImpl< Instruction * > & InitInsts )
static

Collect instructions in the entry block after InsBefore which initialize permanent storage for a function argument.

These instructions must remain in the entry block so that uninitialized values do not appear in backtraces. An added benefit is that this conserves spill slots. This does not move stores before instrumented / "interesting" allocas.
