Hi, I'm working on a port in which BITS_PER_UNIT is 16, Therefore HImode represent 32 bits int and SImode is actually long long. I see many references in gcc code to SImode. Isn't this problematic for ports such as this when SImode does not represent the natural int?
I would like to define PSImode for 36-bit accumulators. Yet, when I'm using attribute mode to define PSImode variable, gcc Is choosing SImode which is the smallest mode for it defined through wider_mode table. I want to define different behavior for PSImode Variables, how can I make sure this mode is actually attached to a variable? Thanks, Tal.
