Oh! I made a mistake by not using setDebugInfo() function present in the Instruction class. Now it's working fully. So, the solution is:- To set the line number for an instruction - 1. Add a function in DebugLoc class located in llvm/Support/DebugLoc.h. Set the line number there to the private variable called LineCol. 2. Call the added function. And then pass the modified DebugLoc object to

Hi, I have a 900,000,000*9,000 matrix where I need to calculate the correlation between all entries along the smaller dimension, thus creating a 9k*9k correlation matrix. This matrix is too big to be uploaded in R, and is saved as a binary file. To access the data in the file I use mmap and some api-functions (to get all values in one row, one column, or one particular value). I'm looking for

Thanks for the help. I thought I'd solved the problem (setting the line number information in the instruction metadata) by inserting my own function for setting line number in llvm/Support/DebugLoc.h. I have added a function setLine(unsigned) in DebugLoc class. The function simply sets the LineCol variable as needed. But there is a problem. Whenever I'm checking the line number(calling

Hi Eric,  I was considering machine instructions to get scope information. And variable declaration does not correspond to machine instruction, hence the problem i.e. no scope associated with it. If 'i' is initialized in the 'if-scope' then we get 'variable i' mapped to correct scope as corresponding machine instruction is generated for this. This is not a problem as we

Thank your reply. Pankaj. Actually, I have done it very similar to yours. But I think for my demand, it is better to implement in Front End. Maybe I will re-implement it later in clang. ---------- Forwarded message ---------- From: Pankaj Gode [via LLVM] <ml-node+s1065342n59345h22 at n5.nabble.com> Date: Mon, Jul 15, 2013 at 2:35 PM Subject: Re: Regarding scope information for variable

Hello, A recent series of commits, ending with r169304 and relating to PR13303, add is_stmt to line entries for functions. This appears to be to work around problems with gdb. However, I observe is_stmt is not always applied to line entries for functions. This may only affect the arm backend. Compiling the same code with the aarch64 backend does not demonstrate this problem. It seems that

Hello, I'm working on implementing GHC specific call convention into LLVM 2.9. I've chosen LLVM 2.9 as a kind of stable reference point and I would like to know how mature is ARM code generation chain inside this release. I've had a hope that perhaps Apple as a main sponsor of LLVM is using LLVM for their ARM based iOS software development, but I'm not sure if I'm right

I am trying to locate instructions in an LLVM Pass by line and column number (reported by an third-party tool) to instrument them. To achieve this, I am compiling my source files with `clang -g -O0 -emit-llvm` and looking for the information in the metadata using this code: const DebugLoc &location = instruction->getDebugLoc(); // location.getLine() // location.getCol()

I have written a wrapper for heatmap.2 called heatmap.w.row.and.col.clust which auto-generates breaks using breaks<-round((c(seq(from=(-20 * stddev), to=(20 * stddev))))/20, digits = 2) #(stddev in this case = 2.5) This has always worked well in the past but now I am getting an error that non-finite breaks are being generated. Drilling down, it seems that my wrapper is generating finite

Hi I'm trying to find the specific place where a MachineInstr is generated from an InlineAsm IR instruction's constant input argument because I want to label it with the correct DebugLoc. Currently, the InlineAsm MachineInstr itself has the correct DebugLoc, but all the MOVs to registers that are spawned for any (e.g. integer) constant input arguments do not have DebugLoc associated with

Hi all, When emitting GC information, it can be very useful to emit the debug location of a GC point, represented as a MCSymbol. Infortunately I haven't found any API (JIT and codegen) where I can get from a MCSymbol to a DebugLoc. Does that interface exist? If not, I plan on committing a small change in the GC code where the debug location is passed to the constructor of a GC point. Patch

Dear all, As you can see from the attachment I'm using R to automatically annotate peptide fragmentation mass spectra, which are represented by impulse plots. I'd like to poll you on approaches of how to deal as generally as possible with the two biggest annotation issues I run into: 1) very close annotated masses (impulses) with similar y-axis dimensions - resulting in overlapping labels

Hi I want to insert some functions into the llvm bitcode ir files. So I use IRBuilder and CreateCall(). But it how error : inlinable function call in a function with debug info must have a !dbg location. I don't know what DebugLoc should I give the new CallInst to setDebugLoc. I Create this CallInst , so this CallInst doesn't hava so-called "DebugLoc" mapping to the source
