Subject: target-arm: Fix 32 bit signed saturating narrow
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cc2212c2f851291929becc3f4fd153d05ca4c54a;p=qemu.git

target-arm: Fix 32 bit signed saturating narrow

The returned value when doing saturating signed 64->32 bit
conversion of a negative number was incorrect due to a missing cast.
