- Subject: [PING] INSN attribute to enable/disable alternatives
Hi,
these 3 patches introduce a new special attribute to be used in INSN
definitions in order to enable or disable certain INSN alternatives.
I think this comes in quite handy when enhancing a back end with new
instructions and I would like to get this in before entering stage 3.
