Subject: softmmu: Dont clobber retaddr in slow_ldx().
X-Git-Tag: TizenStudio_2.0_p2.3~5830
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=446eb51d81f4231464af5f0bad43bfd7284d3137;p=sdk%2Femulator%2Fqemu.git

softmmu: Dont clobber retaddr in slow_ldx().

When splitting up unaligned IO accesses, ld calls slow_ld which was
clobbering retaddr.

AFAIK the problem only shows up when running emulations with -icount
that may abort TB execution on IO accesses.
