Hi Daniel, attached is a patch that pushes most of the object file specific parsing out of AsmParser and down into MachOAsmParser. This was done as a cleanup for the ELF work. I know that you're not happy with this approach, particularly the fact that as we add more object file formats and assembler dialects, it's going to cause a class explosion. But I was hoping that we could use this

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?

Hi, I want to encode Loongson ISA initially https://gist.github.com/xiangzhai/8ae6966e2f02a94e180dd16ff1cd60ac gslbx           $2,0($3,$4) It is equivalent to: dadd $1, $3, $4 lb $2,0($1) I just use  mem_simmptr  as the default value of  DAGOperand MO , because  MipsMemAsmOperand  use  parseMemOperand  to parse general  MemOffset  and only *one*  AnyRegister , for example: 0($1) But 

...are volatile loads in the way. I.E. define i32 @test1(i32* nocapture %p, i32* nocapture %q) { entry: %x = load i32, i32* %p %0 = load volatile i32, i32* %q %y = load i32, i32* %p %add = sub i32 %y, %x ret i32 %add } Currently, getModRefInfo will return Mod for getModRefInfo(%0, AA->getLocation(%y)) This is because it punts on saying anything about ordered loads I can certainly watch for this case in the caller, and ignore it if it's volatile load vs non-volatile load. This is what MemDep does. class Location is theoretically about pointers and sizes, but right now, our struct Loca...

This attempts to address http://llvm.org/bugs/show_bug.cgi?id=18220 It also fixes a test which was requiring the *wrong* output. I'm relatively happy with this part, and it even solves most of the hard part of feature request for .code16 in bug 8684 — which was actually why I started prodding at this. But I could do with some help with the 16-bit signed relocation handling, which I've

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; (2): %...

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!");

Hello, I am trying to emit binary for my implemented vector instructions. Although yet i havent done any change or addition in MC framework, For vector load instruction there are no error coming. But for vector add instruction is something like this; > %R_0_REG2048b_1<def> = P_256B_VADD %R_0_REG2048b_1<kill>, %R_0_REG2048b_0<kill> I am getting the following error: Unknown

Hi, I have this simple program: #include <regex> int main() { std::regex re; re.assign(std::regex("foo")); // SIGILL return 0; } It runs smoothly if compiled with g++ but raises "illegal instruction" when compiled with clang++: g++ -std=c++11 -O0 -g -o test-g++ test.cpp clang++ -std=c++11 -O0 -g -o test-clang++ test.cpp ptomulik at barakus:$ ./test-g++ ptomulik

Hello. I am curious why did you changed TableGen to allow in principle only writing ASM instructions in prefix notation. I ask because I personally use an assembly notation that is infix (I could use a simple preprocessor that changes prefix to infix). Just to mention: I found the solution to this - the following part of the code is responsible for this from

CCing Nick Kledzik as I posed this question on IRC and Tim Northover suggested you as a good resource for this. I came across an error due to a scattered relocation offset being larger than 2**24 and I was hoping to find more information on scattered relocations. These are MachO specific, and Ive not been able to find any documentation on them outside of source code. I have a couple of immediate

When proposing an IR extension, it is usually best to start with a LangRef.html patch so that we can discuss the semantics of the extension. Please do write this before you get much farther. I assume that you want unions usable in the same situations as a struct. However, how do "constant

Hi, On Instructions you can use checkEarlyTargetMatchPredicate() to check that the operands are the same. There's an example of that in MipsAsmParser.cpp for DATI and DAHI. I can't think of a reason TableGen couldn't be made to allow this for InstAlias too. > On 15 Dec 2017, at 02:12, via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Hello, > > InstAlias
