gcc: disable libsanitizer GCC builds this library in order to enable the -fsanitize error detection features. This part of the compile takes several minutes on a Westmere Xeon build server, and to make it worse the build serialises at that point. Our GCC is 6.4 at this point. Running 'op-build toolchain' shows a saving of about 33% (4 minutes) on a 40 core machine and a 25% (6 minutes) on a 2 core machine. We build neither the kernel nor userspace with any of these tools, and probably never will in production. In order to save build time disable libsantizer for GCC builds.

The OpenPOWER firmware build process uses Buildroot to create a toolchain and build the various components of the PNOR firmware, including Hostboot, Skiboot, OCC, Petitboot etc.

To build an image for a Palmetto system:
git clone --recursive git@github.com:open-power/op-build.git cd op-build . op-build-env op-build palmetto_defconfig && op-build
There are also default configurations for other platforms in openpower/configs/ such as Habanero and Firestone.
Buildroot/op-build supports both native and cross-compilation - it will automatically download and build an appropriate toolchain as part of the build process, so you don't need to worry about setting up a cross-compiler. Cross-compiling from a x86-64 host is officially supported.
