I think identifying a minimal "fortran-complete" path would be helpful and encourage people to help out :).Īmd64-linux-siginfo.c: Adjust include order to avoid gnulib error I think the biggest reason people are clamoring for GCC support at the moment is that the platform otherwise has no fortran compiler, which is blocking a lot of the scientific computing stack. Perhaps we can subdivide the work and prioritize what's on the "critical path". I unfortunately don't have very much time myself either, but might able able to pick up a small piece.

The good news is that I don't think there's currently any proprietary ISA extensions that we would have to worry about, so most of the code generation should just go through. Implement parsing/(& printing?) for Apple's assembly dialect
Add special cases for the Aarch64 ABI differences on Apple platforms Is there a list of all the things that need doing? I don't know very much about how GCC is architected (but am familiar with LLVM,MachO,Aarch64 ISA, etc), but from my naive point of view, at least Regards and greetings from Darmstadt, Germany, Thank you very much for your time and help. How do I tell `make` to ignore those features? What other things can I try for `make` to get past `aarch64-builtins.c` and to help get GCC building? 5 features for now, such as memory tagging and pointer authentication. I aim to build for vanilla armv8 so I want to ignore any armv8.3 or. My test hardware is an Apple A12Z SoC, which is based on armv8.3, and I know it definitely doesn’t support memory tagging, nor any other armv8.5 feature. The name of the AARCH64_INIT_MEMTAG_BUILTINS_DECL macro suggests that this is about memory tagging. (The bug tracker seems to allow only a single attachment.) The shell script is self-contained in the sense that it also applies the exact patches I made. I have attached a shell script showing my exact build steps. Make: *** Error 1Īfter `make` fails, I can immediately reproduce the exact same error messages again by running:Ĭd gcc & clang++ -DIN_GCC -Wno-invalid-offsetof -Wno-ignored-attributes -Wno-deprecated -Wno-macro-redefined -Wno-array-bounds -I.

Using information from the `` file from GCC’s source tree, I managed to patch a few things to the best of my knowledge. `make` builds GCC 10.1.0 and exits successfully. For the exact command lines passed to clang, configure and make, please see the attached shell script.Ĭollection of source files for reproducing the bug, preferably a minimal set: Not applicable because I’m trying to build GCC.

I have GNU make 3.81 installed, which was built from source using `brew install make`. I’m running macOS 11.0 beta 1 on Apple Silicon. I’m trying to build (bootstrap) gcc 10.1.0 from the source tarball. But it shows that it’s not entirely unrealistic to build GCC 10 for aarch64/Darwin so I gave it a try. I have learned that it’s completely unfeasible to forward-port those so I haven’t tried that yet.
IIRC, there have been successful third-party efforts to build older GCC versions (such as GCC 4) for aarch64/Darwin already, targeting iOS.

I assume you have heard of Apple’s plans to switch to aarch64 hardware for Macs.Īs a maintainer for the Homebrew package manager for macOS, I’m trying to figure out how to build the most important FOSS projects on the new Apple Silicon hardware. Thanks in advance for hearing me out even though I have near-zero experience in C/C++ programming. Minimal shell script to reproduce the failure
