Oh I see what you mean but I don't think that is the value that I want. In the code, I know that %N = load i32* %k, align 4 %p = getelementptr inbounds [10 x [20 x i32]]* %3, i32 0, i32 %M, i32 %N So I analyze the GEP and know that %N is a pointer to an int32, which is the array index. I want to get that index so I can insert a check to see if it violates the array bounds. So the final code

Hi All, I am new to LLVM. I am trying to get the Hello example in "lib/Transform/Hello" to run. But when I do a make in the directory I get this error. I don't understand why it can't find these make files. ../../../Makefile.common:60: ../../../Makefile.config: No such file or directory ../../../Makefile.common:68: /Makefile.rules: No such file or directory Should i make

Hi Guys, I saw in the API that DominanceFrontier has been deprecated. Is this for real? I have read the computational issues but shouldn't that be left to the users of llvm? My concern is I am writing a Control Dependence module that uses Dominance-Frontier information. Getting rid of Dominance Frontiers will put me in a tight spot.

Hi Everyone, I am new to LLVM and I was wondering whether there is an implementation of PDG (program dependence graph) in the community. I do not want to re-invent the wheel :). Thanks.

Hi Duncan, For this example, getelementptr inbounds [10 x [20 x i32]]* %3, i32 0, i32 %M, i32 %N I am trying to retrieve %N and instrument the program to see if the value pointed to by %N exceeds the array bound (10). I assume that %N will be associated with a load instruction. I have searched through all the tutorials etc. and still have no clue as to how to do this, that is, get the value

Do you mean in llc? Because i don't see such an option i'm afraid. ~George On 24-09-2020 20:54, Johannes Doerfert wrote: > Not that I am an expert but it looks like it defaults to the minimal > PTX version that supports the compute capability.

Hi, First of all, i'm not sure if i should be posting this here or in cfe-dev, but here it goes. In order to instrument CUDA kernels i first generate device IR with: clang++ -x cuda --cuda-device-only -emit-llvm --cuda-gpu-arch=sm_52 -o device.bc I also have a library that contains the instrumentation stubs for which i generate IR similarly and i link it with the device IR

newbie to R, less than a week, and I ordered some books about R, but I learn better by examples.. and thus far I cant find a good example of what I am trying to do... which follows: assuming one is using any instrument intra-day data... I want to.. open a file (lets name it signal) that will contain two fields... date/time(MM/DD/YYYY HH:MM) and signal (1=buy,-1=sell) open a file with real time

That's because instructions have a location associated with them, not a compile unit. -eric On Thu, Oct 4, 2012 at 12:46 PM, George Baah <georgebaah at gmail.com> wrote: > I used DILocation instead of DICompileUnit and it works.

You should probably think of the DIFooBar constructors like reinterpret-casts, not "go find the thing I actually want" functions. If you hand DICompileUnit() a node that is not a compile-unit metadata node, it's not going to tell you that you goofed. If you _did_ have a CU metadata node, then DICompileUnit's getDirectory() would work just fine. But you don't. --paulr

Hmmm, but it has a getDirectory function. -G On Thu, Oct 4, 2012 at 3:50 PM, Eric Christopher <echristo at gmail.com> wrote: > That's because instructions have a location associated with them, not > a compile unit. > > -eric > > On Thu, Oct 4, 2012 at 12:46 PM, George Baah <georgebaah at gmail.com> wrote: > > I used DILocation instead of DICompileUnit and

I used DILocation instead of DICompileUnit and it works. Hmmm, interesting. George On Thu, Oct 4, 2012 at 1:33 AM, George Baah <georgebaah at gmail.com> wrote: > Here is the code.

Here is the code. I am running on llvm 3.1 on Lion (Mac 10.7.4) *string getFileDirectory*(*const* Instruction &I){ MDNode *MD = I.getMetadata("dbg"); DICompileUnit compileUnit(MD); return compileUnit.getDirectory().str(); } George On Wed, Oct 3, 2012 at 12:40 PM, Eric Christopher <echristo at gmail.com>wrote: > Without knowing the code that you've written

I mean an llvm Pass that transforms switch statements into if statements. For example, if I have code with switch statements then running the pass will convert all switches to ifs in the bytecode.

There is also the LowerSwitch pass that converts switch instructions to a sequence of branches.

Yeah, It looks like I am doing exactly what's in Dwarf*.cpp files, yet I am getting blanks.
