What is alias analysis in compilers?
Correct! Well done.
Incorrect.
The correct answer is B) Determining whether two pointers/references may point to the same memory location, enabling optimizations that require independence
B
Correct Answer
Determining whether two pointers/references may point to the same memory location, enabling optimizations that require independence
Explanation
Alias analysis: if p and q may alias, the compiler cannot reorder or optimize p→ writes and q→ reads independently. Must-alias (always), may-alias (possibly), no-alias (never). Key to enabling vectorization and load/store reordering.
