This might give us a hint about what other frontends might expect, and who needs to be involved in the discussion (if one is needed). Cheers, Nicolai > > On Wed, Aug 22, 2018 at 11:41 AM

Hi Mr. Liu, Thanks for your quick reply. I compiled the code with the libclc_trunk and linked the bitcode file under $LIBCLC_DIR/built_libs/tahiti-amdgcn--.bc. After looking into the libclc, it is currently using the new workitem intrinsics (commit ba9858caa1e927a6fcc601e3466faa693835db5e). In the linked bitcode ($LIBCLC_DIR/built_libs/tahiti-amdgcn--.bc), it has the following code segment,

Hi folks (CCing llvm-dev, but that's probably more of a cfe-dev topic), As a follow-up to that old thread about -D_FORTIFY_SOURCE=n http://lists.llvm.org/pipermail/cfe-dev/2015-November/045845.html And, more recently, to this fedora thread where clang/llvm -D_FORTIFY_SOURCE support is claimed to be only partial: https://pagure.io/fesco/issue/2020 I dig into the glibc headers in

Finally I kind of modified llvm to generate assembly that can run on AMDGPU pro drivers. One problem is the performance of the code generated by llvm is about 10% slower than amdgpu's online compiler. Anything I can tune the performance up the performance of llvm?\ Thanks!

Hi folks, some more information on this feature - as a reminder I started one month ago to work on an expensive check that would verify that pass return status is correctly reported by passes, i.e. no pass return « IR not modified » while actually modifying it. It took ~20 pass fixes to achieve that goal, as many passes were not respectful of that contract, but as of

> Out of curiosity, does change here include changes to names, and other semantically-irrelevant changes (e.g., changing the order of operands in a PHI)? The hashing function used to detect changes is currently very simple: it only accounts for instruction opcode and order. So some semantically-irrelevant changes are ignored (as well as some relevant changes), and some are not. Permuting two

Hi folks, Python2 has reached end of support[0], and many core Python packages are dropping pthon 2 support[1]. This is a subject that raises periodically on this mlist, with a rather strong no in 2018 [-1] and a slow move in 2019 [-2, -3]. Even if Python is not a core build requirement, it's used during some configurations steps (e.g. in the cmake export_executable_symbols function), for

Hi Tom, Matt, I'm working on a project that needs few coherent atomic operations (HSA mode: load, store, compare-and-swap) for std::atomic_uint in HCC. the attached patch implements atomic compare and swap for SI+ (untested). I tried to stay within what was available, but there are few issues that I was unsure how to address: 1.) it currently uses v2i32 for both input and output. This

Hi Folks, Although LLVM now relies on cmake for its build configuration, it still calls an external Python script, namely llvm-build, to manage component dependecies, activation or deactivation of target componenents and generating description for llvm-config. This system is documented in http://llvm.org/docs/CommandGuide/llvm-build.html and https://llvm.org/docs/LLVMBuild.html. Several

Hi folks, Per the documentation[0], whenever an LLVM pass doesn't modify the IR it's run on, it should return `false`--it's okay to return `true` if no change happen, just less optimal. In the New PM area, this is generally translated into a `PreservedAnalyses::all()`. https://reviews.llvm.org/D80916 provides an `EXPENSIVE_CHECK` that computes a hash of the IR before and after the

Hi llvm-dev, Every now and then, when building a direct ``CallInst`` either from IRBuilder or through ``Create*``, I have a latent bug because the calling convention (CC) expected by the function is not set on the call, and I need to manually call ``setCallingConv``. Now, from LangRef#calling-conventions, The calling convention of any pair of dynamic caller/callee must match, or the

Hi Folks, Now that LLVM 11.0.0 has been released, it's time to prepare for the final step envisionned in the previous RFC named *[RFC] Python 2 / Python 3 status* [0], ie. requiring Python3.6 for LLVM 12.0.0, to be released in 2021. At least Fedora already only ships Python3 and we didn't have much bugs reported wrt. Python compatibility for the LLVM toolchain. Indeed, all Python scripts

Hi all, I’m currently writing an LLVM function pass and I want to know how can I test it? Currently, I try to compile some crypto library and check if the test suite are working but I don’t think this is very efficient. Does anyone has a leads?

Hi, This patch adds R600/SI disassembly text to compiled object files, when a code dump is requested, to assist debugging in Mesa clients. Here's an example of the output in a Mesa client with a corresponding patch and RADEON_DUMP_SHADERS set: Shader Disassembly: S_WQM_B64 EXEC, EXEC ; BEFE0A7E S_MOV_B32 M0, SGPR6 ; BEFC0306

Hi, When I look at the summary of an rpart object run on my data, I get 7 nodes but when I plot the rpart object, I get only 3 nodes. Should the number of nodes not match in the results of the 2 functions (summary and plot) or it is not always the same? Look forward to your reply, Carol -------------------------------------------- ?summary(rpart.res) Call: rpart(formula = mydata$class ~ ., data
