Subject: tcg-sparc: Fix set-but-not used warnings.
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~4997^2~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b08d26b76d51fb2695912373ded53b628ec96320;p=sdk%2Femulator%2Fqemu.git

tcg-sparc: Fix set-but-not used warnings.

In both cases, val is computed, but then not used in the
subsequent line, which then re-computes the quantity in
a different type (int32_t vs unsigned long).

Keep the computation type that's been working so far.
