similar to: [LLVMdev] TableGen: Requires in multiclass's def as well as defm

Hi list, I'm toying with the idea of writing a m680x0 backend for LLVM, and the address modes of this chip are bewildering, to say the least. Here's a rough list off wikipedia for reference: * Register direct o data register, e.g. "D0" o address register, e.g. "A6" * Register indirect o Simple address, e.g. (A0) o

I have been reading the “RFC/bikeshedding: Separation of instruction and pattern definitions in LLVM backends” topic with considerable interest. This is an approach I have been considering for taming our own large instruction set, and it looks like it structures our descriptions better than the conventional approach we have used so far. However, I have another form of TableGen taming that I

Hi all, I try to run such a line in TableGen but seems it's not working. What is the problem with this code? multiclass cond { let Inst{1-0}=0b11 in defm fxy: ConditionalALU; .... } I receive this error: test.td:162:11: error: expected '=' in let expression let Inst{1-0}=0b11 in defm fxy: ConditionalALU; ^ -------------- next part -------------- An HTML

Bill, Sorry if I wasn't clear enough. I wasn't referring to multiclass's that define other classes, but with using patterns inside of a multiclass to reduce redundant code. For example: multiclass IntSubtract<SDNode node> { def _i8 : Pat<(sub GPRI8:$src0, GPRI8:$src1), (ADD_i8 GPRI8:$src0, (NEGATE_i8 GPRI8:$src1))>; def _i32 : Pat<(sub

I recently upgradeded dovecot on one of our servers from version 1.0.10 to version 1.1.3.

Hi Duncan Sands, I frankly don't know what a variable gets converted to (SSA register or memory chunk). What I meant is, for example I1: int i, j=10; I2: scanf("%d", &j); I3: i = j + 1; Here I want to know whether the value of j in I1 reaches I3 or not. Best Regards, Srikanth Vaindam you didn't define what you mean by a variable. LLVM has virtual registers which are

Hi, I need to find out all the places where the value of a variable is being used. For this I have to implement reaching definitions(def-use chains). When I searched for its implementation I found Iterating over def-use & use-def chains <http://llvm.org/docs/ProgrammersManual.html#iterate_chains>. will this work for finding the places where a variable is reaching? I tried to use

As Raffael suggested, you would need to use an instance variable (@temp) rather than a local variable. The local variable would only be available from the context within which it is called, while the instance variable would be available instance-wide. This sort of situation is where a basic understanding of Ruby comes in handy. A question that I won''t go into, but one that you might want

Dear Community, I'm trying to implement optimization described in PR26223 and meet the following bail out condition in CodeGenPrepare::optimizeMemoryInst. // Break use-def graph loops. if (!Visited.insert(V).second) { Consensus = nullptr; break; } So while traversing thorough phi nodes from memory instruction to find addr mode we bail out if we meet some instruction
