A while back (2012) there were a few messages related to using YAML config files to set up how clang would build stuff, especially for cross compilers. My ELLCC project is entirely cross compilation focused, so today I decided to play around with the config file idea. Right now it only handles replacing a "-target foo" option with the options defined in the file foo in the

ELLCC is a compilation tool chain based on clang/LLVM, libc++ and the musl standard C library for Linux. Recently I was asked if ELLCC pre-built binaries could be used to build clang/LLVM TOT. It turns out that it can with some simple patches. This is a simple way to bootstrap clang/LLVM on an arbitrary Linux system that either doesn't have GCC or has a version of GCC that is too old to

Hi, I asked this question a few days ago and didn't get any responses. I thought I'd try again with a little more detail. I am trying to cross compile my clang/LLVM based ELLCC cross development tools project (http://ellcc.org) on a Mac. I am targeting ARM/Linux. The build fails while building FileCheck (or tbl-gen or any of the other build tools built during the

Hi, I recently switched over to using cmake to build my clang/LLVM based ELLCC cross development project (http://ellcc.org). I also recently updated to LLVM svn version 258915 from 258477. I use ELLCC to cross compile all the tools for various Linux targets and for Windows. Yesterday, after updating the LLVM sources, I got the following error when cross building for MinGW: [ 3%] Built

Hi cschen, Here are the test scripts which I written when I was developing ARM exception handling support: https://github.com/loganchien/libcxx-scripts The script should work on Debian wheezy (cross-compiling from amd64 to armhf.) In general, here are the necessary steps: 1. Get a working arm-linux-gnueabihf gcc/g++ toolchain (for the headers and libraries) 2. Setup the include search path

Today the clang/LLVM based ELLCC compiler (http://ellcc.org) was able to compile an (almost) non-trivial C++ program for a bunch of LLVM supported targets with no gnu licensed libraries. http://ellcc.org/blog/?p=231 Next step: try to compile ELLCC with itself. :-) -Rich -------------- next part -------------- An HTML attachment was scrubbed...

But if I take out my *MUL_LOHI stuff, the error I get is [~/ellcc/ellcc] main% ./nios2-elf-ecc -S test.c

Hi, I've been working on combining LLVM, clang, the NetBSD standard C library, compiler-rt, QEMU, GDB, and GNU binutils as a cross compilation environment. My goal is to target small embedded systems, but I think that what I'm working on may be of interest to other LLVM/clang developers as I have been able to use the environment to fix several code generation issues in LLVM. As of

With all the talk about using lld on the list, I thought it would be interesting to try using it in my clang based ELLCC cross compilation tool chain. http://ellcc.org The change was simple, since I use configuration files to tell clang how to compile, where to find libraries, etc. I described the config files here: http://ellcc.org/blog/?p=13246 All I had to do was change the linker

LLVM Weekly - #39, Sep 29th 2014 ================================ If you prefer, you can read a HTML version of this email at <http://llvmweekly.org/issue/39>. Welcome to the thirty-ninth issue of LLVM Weekly, a weekly newsletter (published every Monday) covering developments in LLVM, Clang, and related projects. LLVM Weekly is brought to you by [Alex Bradbury](http://asbradbury.org).

Hi, I've decided to switch from the NetBSD standard library to the musl library (http://www.etalabs.net/musl/) for my ELLCC (http://ellcc.org) cross compiler project. During my musl feasability study I made a Mips port of musl. A day or two ago, just to make things interesting, I updated to the LLVM TOT (r158294). I started getting assembler warnings about ".set nomicromips".

Hi, Did this make it into review / commit? It's probably too late for 3.6 if it didn't, but I'd love to see it in 3.7. It would also be nice if this support could be something a bit more general in LLVM, rather than specifically in clang, so that other llvm tools (e.g. llvm-objdump) could take advantage of a similar format for target description files if they need something more

Hi vedant, The program didn't pass the checking "OF->getArch() != Triple(Arch).getArch()" loadBinaryFormat in CoverageMappingReader.cpp and returned an error. It's because "OF->getArch()" returned null and "Triple(Arch).getArch()" returned XXXX(name of my arch). The returned value of " OF->getArch()" is decided by "

Hi vedant, 1. The definition is from llvm/Supprot/ELF.h. But this machine information(e_machine) is given to compiler at lib/MC/ELFObjectWriter.cpp. I greped the whole llvm project and found that e_machine was assigned at only two files. One was lib/MC/ELFObjectWriter.cpp(there was an comment said “e_machine=target”) and the other was tools/obj2yaml/elf2yaml.cpp(GDB stopped only at the

Hi all, I'm trying to support llvm-cov for a new architecture and I have successfully built compiler-rt for my arch. Following steps shown in https://clang.llvm.org/docs/SourceBasedCodeCoverage.html , I encountered an error for the last step(step of llvm-cov show). The command line was (supposed my arch is XXXX) "llvm-cov show -arch=XXXX ./foo -instr-profile=foo.profdata" and the

Well, at least it works on some programs across all arches. That was some great testing you've done for us. :-) Thanks!
