similar to: Get timestamp and processor ID in the IR

Hi Hal, Thanks for the pointer. Is it possible to get the processor ID on X86 architecture? There is a library call in linux, sched_getcpu(), to the ID. Also, is it possible to get the program counter in the IR?

Say if we have 8 cores, I want to get which core is running the current program. Thanks.

Hi everyone, when i use the automated dial out,I found that once the zap answerd,the contex will be exectued, but i don't hope do it ,i hope when extern phone answered ,then ,the context will be exectued. Anyone can help me solve the problem! the call file is: Channel: Zap/g0/15015895665 Context: myivr RetryTime: 60 MaxRetries: 2 Waittime: 60 Extension: 808 Priority: 1 Callerid:

Hi, I just started with writing functions in R and so some questions popped up. I provide some values as argument to my function such as: function(a,b,c){} Now i want that the function first checks if the arguments are valid for the function. E.g argument "a" has to be a number in the range 0-1. How can that easily done? So far I have: a <- as.numeric(a) if(0 <= a &&

Hi, I''ve got some problems with setting up environments.

Hi everyone, We seem to have allowed our documented target-independent intrinsics to acquire a somewhat-haphazard naming system, and I think we should standardize on one convention. All of the intrinsics have 'llvm.' as a prefix, and some also have some additional prefix 'llvm.dbg.', 'llvm.eh.', 'llvm.experimental.', etc., but after that we lose consistency. When

What's the API to retrieve current time of day in llc? I need to use this to generate an unique number every time llc runs. TIA - Sanjiv

Thanks, Mats. Actually, it is able to generate the assembly now if I use the follow command: clang++ -O3 -S -mllvm --x86-asm-syntax=intel -mno-sse -o test_nosee.s test.cpp However, when I use g++ -O3 -o test_nosse test_nosse.s -lm to generate the executable, if gives me the following errors: Error: too many memory references for `sub' Error: too many memory references for `mov' Error:

Hi Shahid, Thank you so much for your response. You suggested approach is what I am right now using. However, it seems that the overhead is a little bit high because we are introducing two more instructions. I was wondering if there was a cheaper way to do it.

Is it possible to load a value into a vector register and broadcast it in LLVM? For example, for the following address %x %x = getelementptr inbounds %struct._Ray* %ray, i32 0, i32 0, i32 0 instead of loading the value at %x into a scalar register %0: %0 = load double* %x, align 4, !tbaa !0 I want to load it into a <2 x double> vector register %1 and make both of the two elements in %1

It seems that the problem was because I used builder.CreateFAdd to create a <2 x double> vectortype FADD instruction. It works if I use it to create the scalar version FADD. I want to have an instruction like: *%2 = fadd <2 x double> undef, <2 x double> undef. *The following is the way I used to create the vectorized FADD instruction: //pInst is a double type instruction

I got it. Thanks, Nick. So, it is back to the previous problem. If I have the following instruction: %3 = fadd double %1, double %2 I want to change it into %6 = fadd <2 x double> %4, double %5 where %4 = <double %1, double %1>, %5 = <double %2, double %2>, how can I do this?

Thanks for your response, Sanjay. I know there are intrinsics available in C/C++. But the problem is that I want to instrument my code at the IR level and generate those instructions. I don't want to touch the source code.

Does the insert point also mean inserting before the instruction?

Hi all, I am using gather intrinsic to load a value from the same address twice at the same time. Basically, I used my own pass to changed the following bitcode: %a = getelementptr inbounds [100 x double], [100 x double]* %A, i32, 0, i64 0 %1 = load double, double* a, align to: %a = getelementptr inbounds [100 x double], [100 x double]* %A, i32, 0, i64 0 %splat.a = insertelement <2 x
