The .td file is actually generated by a script and if you notice it already contains some (not many) regular expressions when possible,
For the SKX scheduling, for example, there are many regular expressions that include the broadcast, mask and zeroing bits for all relevant AVX512 instructions.
The problem is that there are not many opportunities to group instructions into regular expressions.
For example, the MMX_* is spread between groups 1, 2,3,8,9,12, etc.
The differences between the groups could be in any of the latency, number of uOps or the ports used by the uOPs.
This makes it hard to use regular expressions.
