Add support for compiling gollvm for other arch by specifying GOLLVM_DRIVER_DIR to a prebuilt gollvm with two targets, and folders of crosscompiler by -L, -I in GOLLVM_EXTRA_GOCFLAGS. Example usage: cmake -Wno-dev -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_CROSSCOMPILING=True -DLLVM_DEFAULT_TARGET_TRIPLE=riscv64-unknown-linux-gnu -DGOLLVM_USE_SPLIT_STACK=OFF -DLLVM_TARGET_ARCH=RISCV64 -DLLVM_TARGETS_TO_BUILD=RISCV -DCMAKE_C_COMPILER=/opt/riscv/bin/riscv64-unknown-linux-gnu-gcc -DCMAKE_CXX_COMPILER=/opt/riscv/bin/riscv64-unknown-linux-gnu-g++ -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS=-latomic -DCMAKE_CXX_FLAGS=-latomic -DCMAKE_INSTALL_PREFIX=/tmp/gollvm-install -DLLVM_USE_LINKER=bfd -DGOLLVM_DEFAULT_LINKER=bfd -DLLVM_TABLEGEN=../build-x86/bin/llvm-tblgen -DCLANG_TABLEGEN=../build-x86/clang-tblgen -DGOLLVM_DRIVER_DIR=../build-x86/bin -DGOLLVM_EXTRA_GOCFLAGS="--target=riscv64-unknown-linux-gnu --gcc-toolchain=/opt/riscv/bin --sysroot=/opt/riscv/sysroot -I /opt/riscv/sysroot/usr/lib64/lp64d -I /opt/riscv/riscv64-unknown-linux-gnu/bin -I /opt/riscv/lib/gcc/riscv64-unknown-linux-gnu/11.1.0 -L/opt/riscv/bin" -G Ninja Change-Id: I557df1ea8e69d4dadaa6c64b7ebc076393d4c530
co-authored with Funan Zeng, Xufan Lu This CL adds linux riscv64 support for Gollvm, with this patch we can build and run Go programs with Gollvm on linux riscv64. The main changes include: 1, RISC-V C ABI implementation. 2, port existing unit test cases on amd64 to risc-v. It should be emphasized that since ld.gold does not support risc-v, we must specify force cmake to use ld.bfd, and add cmake parameter -DGOLLVM_USE_SPLIT_STACK=OFF when building.
