Subject: tcg-sparc: Change AREG0 in generated code to %i0.
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~3472^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0c554161b6fadf75e42d4228e952ff100176ff8a;p=sdk%2Femulator%2Fqemu.git

tcg-sparc: Change AREG0 in generated code to %i0.

We can now move the TCG variable from %g[56] to a call-preserved
windowed register.
