There are few issues with the current ActiveModel::Errors class. Firstly, when an error is added to ActiveModel::Errors class via #add method (https://github.com/rails/rails/blob/master/activemodel/lib/active_model/errors.rb#L294) its translation is added. It should not be translated when being added, but only when being read. The second issue is a bit bigger. We''d like to create error responses in our API similar to GitHub: { "message": "Validation Failed", "errors": [...

...cgi?id=38468. I’ve managed to track it down to a configuration issue. The thing is that in order for libunwind to be usable on ARM Linux, it should be built with the -funwind-tables flag. This flag is conditionally set here: https://github.com/llvm/llvm-project/blob/master/libunwind/CMakeLists.txt#L294, if the compiler “supports” it. However, the CMake check fails with the following error: ``` ld.lld: error: undefined symbol: __aeabi_unwind_cpp_pr0 >>> referenced by src.cxx >>> CMakeFiles/cmTC_e9739.dir/src.cxx.o:(.ARM.exidx.text.main+0x0) clang++: error: link...

Hi, In the runtime system for GHC Haskell, the stack pointer register is not the same as the one defined by the operating system ABI, and it's difficult for GHC to change that. Following the example of CoreCLR in LLVM, it seems one way to remedy this situation is to define a new ABI (i.e., a new llvm::Triple::EnvironmentType ) and modify the code generator as-needed to respect to our ABI,
