One of the early features being merged for what will become the GCC 16 compiler following [1]last week's GCC 15 code branching is CPU targeting support for the XuanTie RISC-V processors.

GCC Git as of today allows "-mcpu=" targeting for various XuanTie RISC-V processor cores. New -mcpu= values are for xt-c908, xt-c908v, xt-c910, xt-c910v2, xt-c920, and xt-c920v2 for the different XuanTie processors.

XuanTie is an Alibaba brand that has been developing different RISC-V cores for cloud computing, AI Acceleration, and related server-focused computing needs.

The XuanTie C920 offers up to four RISC-V cores per cluster, RISC-V Vector 1.0 ISA support, RVA22 profile, and these RV64GCV cores can clock up to 2.5GHz to provide sufficient power for AI, autonomous driving, and related compute needs.

Those interested in this XuanTie xt-c908, xt-c908v, xt-c910, xt-c910v2, xt-c920, and xt-c920v2 -mcpu support now in the GCC 16 compiler can see [2]this commit for all the details.
