Add build-open64-docker.sh, a fully automated script that builds Open64 from source on macOS (Apple Silicon) using Docker with Rosetta emulation. The script handles: - Pre-generating targ_info files natively on ARM64 (avoids Rosetta segfaults in the x86_64 host-tool generators) - Auto-detecting available cores and RAM for optimal Docker allocation - Installing all build dependencies (Ubuntu 20.04, LLVM 11) - Configuring with --disable-jfe and building with system GCC for runtime libraries Also add a "Building on macOS" section to the README pointing to the script. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Update build-open64-docker.sh with fixes from end-to-end testing: - Add 'build' target to step 5 make command so it only compiles the compiler, not runtime libs (which crash under Rosetta with BUILD_COMPILER=SELF) - Add 'set -o pipefail' to step 4 so configure failures aren't silently swallowed by the pipe to tail - Fix targ_info generation: add -DTARG_X8664, compile intermediate .o files, and link GENERATED_OBJS incrementally (matching what the real build system does) Update README to reference the build script in-repo instead of via an external fork URL.

- Remove gcc-multilib/g++-multilib from apt-get install (not needed for a 64-bit-only build) - Pass --disable-multilib to configure, which also forwards it to the bundled GCC via AC_CONFIG_SUBDIRS - Remove --host/--target flags (no longer needed once the x86_64 to i686 downgrade is removed upstream) - Remove make lib2 (32-bit runtime libraries not built with multilib disabled) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
build-open64-docker.sh: a fully automated build script for compiling Open64 inside Docker on macOS with Apple SiliconWhat the script does
The script runs a complete Open64 build in two Docker containers:
ARM64 container (native): builds and runs the
targ_infogenerators (isa_gen,targ_si_gen, etc.) to produce pre-generated headers. These generators segfault under Rosetta x86_64 emulation, so they must run natively.x86_64 container (Rosetta): runs the full configure + build using the pre-generated
targ_infofiles. Runtime libraries are built withLIB_BUILD_COMPILER=GNUto avoid using the freshly-builtopencc, which also crashes under Rosetta.The script auto-detects CPU cores and RAM, installs all dependencies (LLVM/Clang 11, build tools) inside the container, and caches pre-generated files for faster reruns.
Dependencies
This script works best with the following companion PRs (which fix build issues on modern Linux):
