This allows compiling with clang, but using cross binutils for everything else, including the linker. So far tested on riscv 32- and 64-bit and aarch64 (with some hacks to the code to get it to compile - which is why there's no gitlab-ci patch for aarch64 in this series). I suspect it should work for other architectures too. v3: - Add README patch for cross-compiling, clang, and cross-clang [Nick] - Add comment to the commenting-out of mstrict-align [Nick] - Add the reason to ignore warnings vs. fix code to commit message of patch2 - Picked up Nick's tags v2: - fix building with clang and --config-efi by suppressing a warning - added riscv clang efi build to CI - picked up Thomas's tags Andrew Jones (5): riscv: Drop mstrict-align Makefile: Prepare for clang EFI builds configure: Support cross compiling with clang riscv: gitlab-ci: Add clang build tests README: Add cross and clang recipes .gitlab-ci.yml | 43 +++++++++++++++++++++++++++++++++++++++++++ Makefile | 2 ++ README.md | 22 ++++++++++++++++++++++ configure | 11 ++++++++--- riscv/Makefile | 4 +++- 5 files changed, 78 insertions(+), 4 deletions(-)
