Re: Fix reload ICE with define-split

An instruction can have multiple REG_INC notes and with your version it would add a complete set of REG_INC notes for every previous REG_INC note. IMO it's also a bit inconsequent to add REG_INC notes for a register, which didn't have one before, only if there was a REG_INC for a different register.
I'm fine with just recreating existing REG_INC notes or creating REG_INC for all autoinc expressions (even new ones), I'm just not sure about something inbetween.

I'm happy for an RTL maintainer to tell me what the right thing is :)
