These are all the !SHIFT_COUNT_TRUNCATED targets. For 4.5 I would like to improve our RTL canonicalization so that no out-of-range shifts are ever in the RTL representation.
This in turn means that the description given by SHIFT_COUNT_TRUNCATED must be exact. Right now !SHIFT_COUNT_TRUNCATED means "I don't know", I want it to mean "it is never truncated". I would like to know whether for avr,bfin,cris,frv,h8300,pdp11,rs6000 (which define SHIFT_COUNT_TRUNCATED as 0) and for mcore,sh,vax (which do not define it at all) it is right that shift counts are never truncated. In addition, for arm and m68k I'd like to know whether bitfield instructions truncate the bit position the same as shifts (8 bits for arm, 6 bits for m68k). This information is particularly important for targets that do not have a simulator in src. Thanks in advance! Paolo
