Subject: [PATCH] re PR target/53272 (wrong condition-codes for strict-low-part
destination and small-integer source)
PR target/53272
* config/cris/cris.c (cris_normal_notice_update_cc): For TARGET_V32,
when a constant source operand matches an "I" constraint, the "no
CC0 change" applies to a register-destination only, not a
strict_low_part-destination.
