Subject: target-m68k: Fix cmpa operand size
X-Git-Tag: v2.8.0-rc2~9^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5436c29d78957a6825a93f0eb79dfab388641017;p=thirdparty%2Fqemu.git

target-m68k: Fix cmpa operand size

"The size of the operation can be specified as word or long.
Word length source operands are sign-extended to 32 bits for
comparison."

So comparison is always done using OS_LONG.
