Hello Jonathan, Just FYI, I started doing review of your patch and will get back to you in few days. After review, I would like to rebase your patch (as necessary) myself and do some testing.. and re-submit.

Viswenath, My patch should be against the tip, but it?s the very recent tip, including some changes this past Friday (27 Feb). I mentioned in the IRC room a problem I discovered in creating my patch, and then later improved the fix Tim had made for the problem. Where do you get conflicts merging it to tip? In terms of merging, you posted your patch before I posted mine, so probably I should be

Hello Hal, I am not very familiar with the DSP capabilities of PowerPC, but I imagine there will be instructions for simple vector operations like vector addition, multiplication, etc. so for these I imagine the implementation would consist of just outputting the correct instruction. However, for NEON instructions like the reciprocal step (see

Hi Robert, Can you ping the code owners about these patches. It might be good to write a separate email per code owner and cc the appropriate -commits list.

Hi, I have just tagged the first release candidate for the 3.4.1 release, so testers may begin testing. Please refer to http://llvm.org/docs/ReleaseProcess.html for information on how to validate a release. If you have any questions or need something clarified, just email the list. For the 3.4.1 release we want to compare test results against 3.4-final. I have added support to the

Speaking of conversion, do we actually have Neon code for int<->float conversion? Jean-Marc On 01/02/15 05:26 PM, Timothy B.

Hi there, I am Software product developer at Robert Bosch, Germany. We are using armv8 64bit targets for our development. We have the need to do the cross compiling for our target on windows. I have compiled clang 5.0 from the vcs git. I have tried compiling the code with following options set: clang.exe -target armv8 -fslp-vectorize-aggressive -mfpu=neon -mfloat-abi=hard -c test.cpp As you

Hi, all, Does Opus need celt_pitch_xcorr' s fixed point version for ARM aarch64 architecture? If yes, which version does Opus prefer: assembly or instrinsics?

That?s an obvious next step. This doesn?t show any appreciable speed difference in my tests, but the code is obviously better by inspection (all three of these map directly to a single Aarch64

Hi GlobalISel interested parties, A recent bug report (https://bugs.llvm.org/show_bug.cgi?id=40968) on AArch64 exposed a problem with our modeling of intrinsic semantics when dealing with type overloaded calls. The crux of the matter is that because GlobalISel’s LowLevelTypes only carry size and vector layout information, and not any information about whether a type is integer or fp, we lose

Hello LLVM Devs, I am starting my PhD on Automatic Parallelization for DSP and want to play with some ARM NEON intrinsics for a start. I spent the last three days trying to compile a version of LLVM that would allow me to compile sources that contain these intrinsics, but with no success. In the process I found out that clang doesn't support NEON (as per

Hello LLVM Devs, Thanks for helping me previously to cross-compile for ARM, I managed to get a working toolchain and am currently having fun compiling different toy problems and running them on a pandaboard. As part of my research I am trying to implement the ARM NEON Intrinsics in the PowerPC LLVM backend. I am still at the beginning of my efforts and am not yet familiar with either the ARM or
