Hello again, Couple of things.
First, it is important to keep in mind that the "llvm-goc" binary is not intended to be used as a top level go compiler, in the same way that the "gcc" or "clang" commands are used as top-level C/C++ compilers. The normal use case is to use "go build" as opposed to invoking llvm-goc directly. Just to recap: build the 'install-gollvm' ninja target (as described in https://go.googlesource.com/gollvm/#installing), prepend the install dir "bin" directory in your path, and then run "go build". It's also problematic to run llvm-goc directly out of the build area instead of doing and install and using the copy in the install dir. For example, if I do a build of llvm-goc in my LLVM build area, then invoke it directly on a small Go program, this is what I see: $ ./bin/llvm-goc smallmain.go /usr/bin/ld.gold: error: cannot find -lgobegin /usr/bin/ld.gold: error: cannot find -lgo /usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/crt1.o:function _start: error: undefined reference to 'main' <built-in>:1: error: undefined reference to 'runtime.registerTypeDescriptors' smallmain.go:4: error: undefined reference to 'runtime.printlock' smallmain.go:4: error: undefined reference to 'runtime.printint' smallmain.go:4: error: undefined reference to 'runtime.printnl' smallmain.go:4: error: undefined reference to 'runtime.printunlock' $ Here the compiler is unable to find the right runtime libraries. I'll see if I can update the documentation to make this a little clearer. Regarding the crash you're seeing when building from LLVM: 43ff75f2c3feef64f9d73328230d34dac8832a91 gollvm: 44a7a475cfd3b871b7a5a0941b8ab1ea9d489adc gofrontend: be0d2cc2df9f98d967c242594838f86362dae2e7 libbacktrace: 5a99ff7fed66b8ea8f09c9805c138524a7035ece libffi: 737d4faa00d681b4c758057f67e1a02d813d01c2 Sorry, but I can't reproduce your crash (I did another build using the config above and it seems to work ok). What is the exact cmake command you're using to set up your build area? You might also try this: in your LLVM build area, run "ninja llvm-symbolizer" and then set export LLVM_SYMBOLIZER=${HERE}/bin/llvm-symbolizer then rerun the failing "llvm-goc" invocation, that might give you a better stack trace.
