New Revision: 245539
URL: http://svnweb.freebsd.org/changeset/base/245539
Log:
Add compiler support for the ARM EABI.
ARM EABI support is disabled by default and can be enabled by setting
WITH_ARM_EABI when building, however only the kernel-toolchain target will
work with this flag until the rest of the support is added.
Added:
head/tools/build/options/WITH_ARM_EABI (contents, props changed)
