This patch modifies the function in genfusion.pl for generating
the logical-logical patterns so that it can also generate the
add-logical and logical-add patterns which are very similar.

Two more sets of combine patterns for p10 fusion. These require
the "Add insn types for fusion pairs" patch I posted earlier today.
If ok I would like to put these in gcc 12 trunk and backport for 11.2.
Thanks,

This adds new values for insn attr type for p10 fusion. The genfusion.pl

PR99070 is caused by a fusion pattern matching that the individual

In a previous fusion-combine patch for rs6000, Segher had asked me to

One of the things that address_to_insn_form() is used for is determining
