I want to insert new alloca Instruction after existing alloca Instruction in llvm pass so what attribute to be passed at last in following newallocaI = new AllocaInst(llvm::Type::getInt32PtrTy(context,0), //type 0, // ArraySize 8, // Alignment

Hi Developer, In my processor I am not using registers so I wrote Simple register.td file with bare minimum functions. But when I am registering my target with llvm it is showing "*Segmentation Fault(core dumped)*" Error and also same error while generating table-gen for asm-writer. Some one told comment out EditRegesterName function. because this error is due to EditRegisterName it

Hi Developer, I have wrote simple program called test.c as follows. *int a, b;int main() {a=10;b=10;return a+b;}* Compiled with clang command to produce test.ll file which is attached below, *$clang -cc1 test.c -emit-llvm* Now If I want to run with my own target for selection with *llc* with command as follow getting error, *COMMAND:$ ./llc -view-dag-combine1-dags -march=toy

Hi Developers, I have written C program and want to generate IR file for Specific Target I have tried with following command but got a error as follows, COMMAND: *clang -S -emit-llvm -march=leg ~/llc-test-examples/ex9.c -o ~/llc-test-examples/ex9.ll* ERROR: *error: unknown target CPU 'leg'* So any please help me what all other step should I do previously to get my *leg* target in clang.

HI developers, I want to add trigonometric instructions in my instrinfo.td files how can i directly map these instructions in .td files. Please help me Guys.For Sin, Cos, Tan and Cot Instructions. If I used llvm.sin.* as SDNode Then it is error as llvm variable is not defined SO please Help me. Thanks and Regards Varun -------------- next part -------------- An HTML attachment was scrubbed...

The LLVA and LLVM papers motivate the GetElementPtr instruction by arguing that it abstracts implementation details, in particular pointer size, from the compiler. While it does this fine for pointer addresses, it does not manage it for address offsets. Consider the following code: $ cat test.c int main() { int *x[2]; int **y = &x[1]; return (y - x); } $ llvm-gcc -O3 -c test.c

Do you mean inttoptr here? And that "all pointer values that contribute (directly or indirectly) to the computation of the

Hi Varun, I see the point of your question, but I'm not the best person to answer from that perspective. Nadav Rotem is the owner of the x86 backend, and he can probably give you a more complete answer than I could.

Hi all, What exactly are the rules for `getelementptr inbounds` with offset 0? In Rust, we are relying on the fact that if we use, for example, `inttoptr` to turn `4` into a pointer, we can then do `getelementptr inbounds` with offset 0 on that without LLVM deducing that there actually is any dereferencable memory at location 4. The argument is that we can think of there being a zero-sized

Hi Andrew, I think I diluted my question. My question was not related to MCJIT. I ran the following 4 scenarios: (1)gcc -mcpu=corei7 tetris.c -o tetris (2)gcc -mcpu=athlon64 tetris.c -o tetris (3)clang -march=corei7 tetris.c -o tetris (4)clang -march=athlon64 tetris.c -o tetris In (1) and (2), I see difference in order of instructions in the output binaries, which I expected because every CPU

By default the prototype.js gives us the function /* prevent memory leaks in IE */ Event.observe(window, ''unload'', Event.unloadCache, false); But there is no unload event in out application as the content of the div keeps changing using the Ajax.Updater function. To handle such a scenario, we''ve added the following lines of code to prototype.js /* prevent

Hi Hal, Thanks for your hint! $ /opt/llvm-svn/bin/opt -S -internalize -internalize-public-api-list=main -globaldce hello3.ll -o hello3.dce.ll    it works :) But I argue that `main` Function should be inserted into ExternalNames by default: Index: lib/Transforms/IPO/Internalize.cpp =================================================================== --- lib/Transforms/IPO/Internalize.cpp

Hi, 1. I have 2 panes, each having approximately 45-50 slides, all the slide images are 110x82 pixels in size, enclosed in their respective div''s. 2. These divs are further enclosed in a parent div, which is defined as a Sortable on page load. 3. There is a destination div on the RHS also. Sortable.create("div_leftDiv", {ghosting:true, revert: true, dropOnEmpty:true,

Hi Varun, Have you tried your experiment with icc by any chance? The MCJIT component does not assume that you will be executing the generated code on the host system because it can be used to generate code for external targets. However, you can specify the CPU by calling setCPU() on the EngineBuilder object before creating your execution engine. (You can use sys::getHostCPUName() to figure out

Hi Duncan, A DragonEgg/GCC-related question: do you know where these strange FRAME tokens originate from (e.g. %struct.FRAME.matmul)? Compiling simple Fortran code with DragonEgg: > cat matmul.f90 subroutine matmul(nx, ny, nz) implicit none integer :: nx, ny, nz real, dimension(nx, ny) :: A real, dimension(ny, nz) :: B real, dimension(nx, nz) :: C integer :: i, j, k real,

In Sortables, we have a function onHover: onHover: function(element, dropon, overlap) { if(overlap>0.5) { Sortable.mark(dropon, ''before''); if(dropon.previousSibling != element) { var oldParentNode = element.parentNode; element.style.visibility = "hidden"; // fix gecko rendering
