Developers from ARM Holdings have published their initial ARMv8 patch for the GNU Compiler Collection for the 32-bit "AArch32" compiler port.
ARM developers had already been working on their 64-bit ARM / AArch64 compiler port
, which was officially approved
just days ago. The latest ARM open-source compiler patch is ARMv8 in the AArch32 port with basic functionality.
This work basically allows for a armv8-a
target for setting -march=armv8-a
when building out software for Linux on ARM. Compared to ARMv7 on 32-bit ARM, the ARMv8 revision supports new NEON cryptographic functionality.
The ARMv8 GCC patch is currently sitting on the patches mailing list
