The latest Intel programming reference manual has dropped AMX-TF32 and Intel engineers are already moving ahead to strip out the AMX-TF32 support that existed in the GNU Compiler Collection. Intel updated their ISA programming reference manual and the newly-published version now eliminates AMX-TF32 as well as User-Timer Events and Interrupts. AMX-TF32 was the planned ISA extension for adding the NVIDIA TensorFloat-32 "TF32" format natively to Advanced Matrix Extensions (AMX). TF32 allows the range of FP32 but with the performance of FP16 for AI/matrix computations. Intel documentation Diamond Rapids processors are expected to launch in 2027 while now AMX-TF32 is being stripped away as a late change.

The support is being stripped away given "*no actual hardware*" is availablr with this functionality. It's also dropping AMX-TF32 from the Diamond Rapids target. As Diamond Rapids appeared in GCC 15 and GCC 16 with AMX-TF32 support included, back-ported patches are now needed to remove that feature.AMX-TF32 now shares a similar fate of
