Hi,
I'm looking at gcc-nios2 options -march.
It seems two instruction sets can be selected (r1/r2) but I cannot find out where theses instructions set are described.
On the other end I found this document https://www.altera.com/content/dam/altera-www/global/en_US/pdfs/literature/hb/nios2/n2cpu_nii51017.pdf which describes several updates of the instruction set (section Document Revision History) from 2004 to 2015.
I'm looking for a recent gcc-nios2 compiler compatible pour nios2 version 6.1 (November 2006) i.e. without the 'jmpi' instruction.
Do I have to modify the backend to add a -mno-jmpi option ?
Regards,
Selim
