Subject: target/avr: Avoid use of tcg_const_i32 in SBIC, SBIS
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=353c18dc02a7470f7edde915cd49a59753066bbe;p=qmiga%2Fqemu.git

target/avr: Avoid use of tcg_const_i32 in SBIC, SBIS

The use of separate data/port variables is existing
practice elsewhere, e.g. SBI, CBI.
