Subject: target-sh4: Let cpu_sh4_init() return SuperHCPU
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~4039^2~44
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=445e957194807aa9eb1d02c23430dbb0c6bac34e;p=sdk%2Femulator%2Fqemu.git

target-sh4: Let cpu_sh4_init() return SuperHCPU

Turn cpu_init macro into a static inline function returning
CPUSH4State for backwards compatibility.
