Subject: tcg-ppc64: Use tcg_out_{ld,st,cmp} internally
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~752^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c3831a088de45ca431abe1f17511cf6589f207c;p=sdk%2Femulator%2Fqemu.git

tcg-ppc64: Use tcg_out_{ld,st,cmp} internally

Rather than using tcg_out32 and opcodes directly.  This allows us
to remove LD_ADDR and CMP_L macros.
