Oh, got it. Thanks for your explain. I misunderstand what getLocation does. If I would like to get the result of alias analysis referring to the stored value, what should I do in llvm?

...are volatile loads in the way.

Hi all, I am implementing a pass which needs aliasanalysis in llvm. My pass firstly records all store or load instructions as follows: loc[cnt++] = AA.getLocation(si/li); Then, get each pairwise alias result. AliasAnalysis::AliasResult ar = AA.alias(loc[i], loc[j]); switch(ar){ case 0,1,2,3;} And the command is: opt -load mypass.so -mypass -basicaa test.bc The store/load in test.bc: (1): store i64* %thd, i64** %t, align 8 //int64 *t = &thd; (...

Hello, InstAlias does not allow tied operands (repeated operands) in the asm string to be matched. It seems this situation is explicitly prevented in AsmMatcherEmitter.cpp: if (!Hack) PrintFatalError(TheDef->getLoc(), "ERROR: matchable with tied operand '" + Tok + "' can never be matched!"); // FIXME: Should reject these. The ARM backend hits this with $lane in a // bunch of instructions. It is unclear what the righ...
