Good to know, thanks! How do I run regression-testing with this target however? I can see QEMU support upstream, even for user-mode Linux, which would be the easiest to run (sadly toolchain support for CRIS/Linux was removed a while ago as was the Linux kernel port; at one point I even considered getting myself a CRIS development board as an alternative RISC platform that would Linux, but concluded that it was too expensive for the features it offered), but for a bare metal environment both a C library (newlib?) and then a specific board support package is required. Or may I ask you to put this patch through testing with your environment? > Your proposed patch reminded me of 6cb68940dcf9; giving reload a > reload-specific insn_and_split pattern to play with, matching > "mult" outside of a mem.
