Mine is ]Linaro 4.6.3 which supports it fine, but the feature may be a Linaro ]contribution that only made it into 4.7 upstream. In any case, we ]cannot tolerate unaligned accesses so we may need to deprecate 4.6 or ]mandate that the Linaro version be used if older versions emit ]unaligned accesses. The GCC46 is the Windows hosted build from: http://sourceforge.net/projects/edk2developertoolsforwindows/ It is built from the latest gcc 4.6 source code: http://ftpmirror.gnu.org/gcc/gcc-4.6.4/gcc-4.6.4.tar.bz2 Using built-in specs.
