Subject: target-alpha: Fix compiler warning for gcc-4.3 (and older)
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~9296

target-alpha: Fix compiler warning for gcc-4.3 (and older)

"Old" compilers obviously are not able to recognise
that all cases are handled here:

qemu/target-alpha/helper.c:70: error: ‘round_mode’ may be used uninitialized in this function

A small modification helps the compiler to do its jobs.

gcc-4.4 does not need this, but is still not standard on all platforms.
