Success: Bring-up of LLVM/clang-built Linux ARM(32-bit) kernel for Android - Nexus 5
...w. To be fair, the GCC version which comes with the android ndk has not been updated for four years, while the clang version is kept up-to-date. It would be interesting to compare clang and GCC latest releases instead... that's where the future lies :p ------- Jean-Michaël Celerier http://www.jcelerier.name -------------- next part -------------- An HTML attachment was scrubbed...

LLJIT: __{math}_finite symbols not resolved ?
...hink you need a glibc-2.31 at least for that behaviour to be visible)'s glibc symbols became versioned. Removing either the -fmath-errno or -ffinite-math-only flag for the clang cpp -> bitcode invocation in build.sh fixes the issue (at the expense of potentially slower code). <http://www.jcelerier.name> Thanks for the hint, sadly it's not possible to take the address of __log_finite : what happens is that you call the function e.g. log() in your code, and either clang or some magic glibc header transforms that into __log_finite further down the pipeline (see e.g. the discussion in htt...

Clang API: any way to use a virtual filesystem ?
Hello, I am shipping my app (https://ossia.io) with an embedded clang to allow people to write extensions in C++ at run-time. For that to work I also ship a SDK with all the required headers, libc++, etc... which is downloaded & extracted in some folder. Problem is: while on my linux dev. machine this operation is fast, apparently on Windows and mac extracting a .zip with a few thousand

LLJIT: __{math}_finite symbols not resolved ?
Hello, Right now I am just using a Generator to look for symbols in my process (which links dynamically against libc / libm). It seems to have no trouble finding every other libc / libm / libc++ / ... symbol so I assumed that it was not necessary to specifically link against libm where these __finite symbols reside: $ nm -D /usr/lib/libm.so.6 | grep finite 0000000000050540 T

Using C++14 code in LLVM
...s version of MSVC supports C++17 but deploying through corporate IT can take a while. But this does apply to LLVM versions, to, doesn't it ? What's the problem with LLVM 9 using c++17 if you can only develop based on LLVM 5 at your shop anyways ? ------- Jean-Michaël Celerier http://www.jcelerier.name On Thu, May 10, 2018 at 9:20 PM, via llvm-dev <llvm-dev at lists.llvm.org> wrote: > Well… Ubuntu 16.04 came with gcc 5, and deploying Visual Studio 2015 > should be a done deal in Windows shops, which suggests moving to C++14 > should be no problem. > > > > It'...

Success: Bring-up of LLVM/clang-built Linux ARM(32-bit) kernel for Android - Nexus 5
Hello, I would like to share my successful bring-up of LLVM/clang-built Linux ARM(32-bit) hammerhead kernel for Android running on my Nexus 5 smartphone. After having successfully brought up LLVM/clang-built Linux kernel(since v4.15.7 to the most recent v4.17) on x86_64, I was interested in accomplishing the same on the ARM platform of my Nexus 5 - Android smartphone. So, here is the complete

Using C++14 code in LLVM
Well… Ubuntu 16.04 came with gcc 5, and deploying Visual Studio 2015 should be a done deal in Windows shops, which suggests moving to C++14 should be no problem. It's nice to see this week's version of MSVC supports C++17 but deploying through corporate IT can take a while. ("This week's version" because the blog post is dated Monday.) --paulr From: llvm-dev
