similar to: [LLVMdev] Tablegen problem populating TSFlags

My brief investigation seems to point at this having to do with the let altering the base class, which prevents the usual resolution from occurring (presumably the resolution has already happened for the base). I'll dig into this tomorrow. -- Sean Silva

An extra call to resolveReferences after setting the value in the `let` does fix this, but I'm not sure that it is the right fix. The attached hackish patch seems to fix up a reduced version of the test case you gave here (I haven't run a full battery of tests on it, so it might cause other failures). Jakob, any idea about what the "right" fix is here? -- Sean Silva

I am a relatively new user to R, and I am trying to learn more about converting data in an XML document into "2-dimensional format" such as a table or array. I might eventually wish to export this data into a relational database such as SQL, and/or to work with this data within the R package. My sample XML document is located at "

Jakob, I think this exactly what's happening. I debugged the resolveReferences for the ADD down into the resolve of TSFlags. It calls VarInit::getFieldInit for the "Val" field of "foo". The code is: Init *VarInit::getFieldInit(Record &R, const RecordVal *RV, const std::string &FieldName) const { if (isa<RecordRecTy>(getType()))

Hello LLVM, I'd like to check TSFlags in my AsmBackend code. However AsmBackend objects don't have a reference to MCInstrInfo, which is the only way I've seen to reach TSFlags. A quickie grep shows that none of the existing targets check TSFlags in their AsmBackends. Is there any reason I shouldn't check TSFlags in AsmBackend? If not, what's the best way to go about it?

Hi guys, I am a newbie to R, so apologies in advance. I created this simple table in excel, saved in tab delimited .txt: name value_1 value_2 1 bill 1 4 2 ben 2 2 3 jane 3 1 >test <-read.table("\path\to\file", sep="\t", header=TRUE) >x <-c(seq["value_1"]) >y <-c(seq["value_2"])

Hello ! I have a toolchain of two passes. First one, is a transformation pass that should add metadata to some structures (instructions/variables) and the second pass is an analyzing pass which needs to access the added metadata. The problem is with my adding metadata transformation pass. There might be two problems(or both): First, maybe I don't add correctly metadata.

Hello all, I wan to ask, what is exactly the purpose of TSFlags and can it be used for the condition handling in instructions? How can I implement the conditions in the instruction when I don't have access to the Status Register? Best regards, ES -------------- next part -------------- An HTML attachment was scrubbed...

Hi Krzystof, regarding your first solution (creating separate instruction), is it possible to somehow have cascading defm? for example, let's suppose aaa is a 3-bit condition a, and bb is a 2-bit condition b, all in one instruction, instead of having one multiclass with 2^5 conditions, is it possible to write 2^3 "a" conditions, and 2^2 "b" conditions, and the rest taken

Many thanks for your prompt reply. I mean, imagine you have 3 bits for condition flags in your instruction (e.g. overflow, zero, carry set, ...) for conditional executions AND there is no direct access to the Status Register, is it even possible to implement such scenario?

Hello, I am finding that the melt function from the reshape library causes errors when applied to a data.frame that contains numeric and character columns. For example, melt(id.vars="ID",data.frame(ID=1:3,date=c("a","b","c"),value=c(1,4,5))) ID variable value 1 1 date a 2 2 date b 3 3 date c 4 1 value <NA> 5 2

Ah, I think I get it now. This was mentioned earlier in the thread, but it didn't click at the time. It sounds like I can do instruction selection with a pattern like (omitting selection of the sources): let Constraints = "$dst = $oldvalue" in { def MASKEDARITH : MyInstruction< (outs VectorReg:$dst), (ins MaskReg:$mask, VectorReg:$src1, VectorReg:$src2,

Hi @ all, how do I get the largest or lowest k values of list? It must similar to the min() / max() function, but I just don't get it. Best wishes, Markus

I think we can get rid of the TSFlagsFields and TSFlagsShifts hack in the InstrInfo TableGen class now. This seems to work just fine: class Instruction { bits<32> TSFlags; } class Domain<bits<2> val> { bits<2> Value = val; } def GenericDomain : Domain<0>; def SSEPackedInt : Domain<1>; def SSEPackedSingle : Domain<2>; def SSEPackedDouble :
