@shepmaster: This sounds related to your recent change?
@PeterZegelin: If you want, feel free to submit a PR with your fixes :)
I think this is fixed in #191, but no, I don't believe it's related to any changes I've made.
Hey @shepmaster, I checked out your branch, and it runs into slightly different compilation problem:
[ 74%] Building CXX object tools/clang/lib/Basic/CMakeFiles/clangBasic.dir/Targets.cpp.o

@KarstenB to be sure, you mean this branch, right? Which SHA are you at? The branch compiled at last check, as you can see by the PR being green 😸

I essentially did:
$ git clone -b track-upstream --depth 1 https://github.com/shepmaster/llvm.git
$ cd llvm/tools/
$ git clone --depth 1 https://github.com/avr-llvm/clang.git
$ cd ../projects/
$ git clone --depth 1 https://github.com/avr-llvm/compiler-rt.git
$ cd ..
$ mkdir build
$ cd build/
$ cmake -G "Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="AVR" ../
$ make
Oh, I missed you were compiling clang! For my usecase, I don't need clang, so I haven't been doing anything with that. It's probably likely that you will need to update the clang and compiler-rt repositories to new(er) versions to correspond to the new(er) LLVM versions.
I'm gonna update clang now.
Clang now compiles, and is also a part of the Travis-CI build.
Thanks, it now works for me :)
After following all the instructions on the Wiki for building avr-llvm the make process failed about 31% in lib/Target/AVR/AVRFrameLowering.cpp
The specific error is: error: virtual function 'eliminateCallFramePseudoInstr' has a different return type ('void') than the function it overrides (which has return type 'MachineBasicBlock::iterator' (aka 'MachineInstrBundleIteratorllvm::MachineInstr'))
I 'fixed' this by specifying the correct return type and returning MBB.erase(MI) and compilation continued only to fail again shortly after in AVRISelDAGToDAG.cpp with a another function having different return types: error: virtual function 'Select' has a different return type ('llvm::SDNode ') than the function it overrides (which has return type 'void') SDNode Select(SDNode *N) override;
