Summary: Refactor getInterestingMemoryOperands() so that information about the pointer operand is returned through an array of structures instead of passing each piece of information separately by-value. This is in preparation for returning information about multiple pointer operands from a single instruction. A side effect is that, instead of repeatedly generating the same information through isInterestingMemoryAccess(), it is now simply collected once and then passed around; that's probably more efficient. HWAddressSanitizer has a bunch of copypasted code from AddressSanitizer, so these changes have to be duplicated. This is patch 3/4 of a patch series: https://reviews.llvm.org/D77616 [PATCH 1/4] [AddressSanitizer] Refactor ClDebug{Min,Max} handling https://reviews.llvm.org/D77617 [PATCH 2/4] [AddressSanitizer] Split out memory intrinsic handling https://reviews.llvm.org/D77618 [PATCH 3/4] [AddressSanitizer] Refactor: Permit >1 interesting operands per instruction https://reviews.llvm.org/D77619 [PATCH 4/4] [AddressSanitizer] Instrument byval call arguments [glider: renamed llvm::InterestingMemoryOperand::Type to OpType to fix GCC compilation] Reviewers: kcc, glider Reviewed By: glider Subscribers: hiraditya, jfb, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D77618 |
