• Subject: Extracting destination register from an instruction

Hello Everyone, I have a question about finding register names from the instruction. I am porting GCC for a propriatery architecture and the thing is that, I want to group instructions whose destination registers are between 0-15 into one cluster and 16-31 in another. Firstly, I was under the impression that the only way I can do this is in the machine_dependent reorganization phase? Is there another way to do this?

Also, how can I extract destination register information from the instruction?

Any help is highly appreciated.

Thanking You,

Yours Sincerely,

Balaji V. Iyer.
