is it
someone's at thedoor \МПО IS
Swapping without using a third variable 3
a=a+b;
а =а 4
JESSE! JESSE!!! YOUR INTEGER OVERFLOW VULNERABILITY IS
MAKING DENNIS RITCHIE ROLL IN HIS GRAVE! THE MODERN LLVM COMPILER PIPELINE HAS SPENT
DECADES OPTIMIZING TEMPORARY VARIABLE ALLOCATION WITH SSA FORM, WHILE YOUR
CODE IS DESTROYING BOTH THE ARM AND PIPELINE'S ABILITY TO PERFORM SPECULATIVE EXECUTION!
YOUR ARITHMETIC TRICKS ARE CREATING SERIAL DEPENDENCIES IN THE CPU'S RESERVATION
STATIONS, COMPLETELY NULLIFYING OUT-OF-ORDER EXECUTION! THE CACHE PREFETCH LOGIC
CAN'T ESTABLISH ANY COHERENT STRIDE PATTERN, THE BRANCH PREDICTION UNIT IS STALLING ON
EVERY SPECULATIVE PATH, AND THE LOAD-STORE UNIT'S MEMORY DISAMBIGUATION LOGIC CAN'T
MAINTAIN COHERENCY! AND DON'T YOU DARE SUGGEST YOUR XOR SWAP IT CREATES A SERIAL
DEPENDENCY CHAIN THAT DESTROYS INSTRUCTION LEVEL PARALLELISM AND PREVENTS BOTH
MICRO-OP AND MACRO-OP FUSION ON MODERN ARCHITECTURES! A CLEAN TEMPORARY VARIABLE
ALLOWS THE REGISTER ALLOCATOR TO MAINTAIN OPTIMAL REGISTER PRESSURE AND ENABLES
FORWARDING! BUT NO, YOU HAD ТО PLAY CODE GOLF AND CREATE NON-TEMPORAL
MEMORY ACCESS PATTERNS THAT DESTROY CACHE LOCALITY! THE PAGE TABLE WALKER IS THRASHING,
AND THE TLB HIT RATE HAS DROPPED TO SINGLE DIGITS!
