I am really confuse here, what are the sub-standard solutions which are u referring to? And what is the GNU standard which you also invoke?

Not sure how to interpret this paragraph either. We (Synopsys) are in the process of upgrading the ARC ABI exactly for this reason: to get first class solutions always among all our toolchains. I do not understand on what basis you do the above accusations.

Your opposition is noted. I have updated the patch using options, and this is solving the disassembler problem. The proposed solution is not unique among other backends, and hence, it cannot be neither called "second rate solution" nor out of GNU standards.
