Subject: include/exec/softmmu-semi.h: Add support for 64-bit values
X-Git-Tag: TizenStudio_2.0_p2.3.2~120^2~1^2~215^2~21
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=44d4a499b79d12d5c29f32bf2070c89335573c03;p=sdk%2Femulator%2Fqemu.git

include/exec/softmmu-semi.h: Add support for 64-bit values

Add support for getting and setting 64-bit values in the
softmmu semihosting support functions. This will be needed
for 64-bit ARM semihosting.
