Support for the AMX-TF32 instruction set has been removed from GCC. This follows the deprecation and removal of AMX-TRANSPOSE from Intel’s Instruction Set Extensions (ISE). The removal affects various parts of the compiler, including CPU feature detection, intrinsic functions, and documentation. Parts of this change are backported to GCC 15 and 16.
