Subject: Added the x86 INT instructions; both the special-case INT 3 and the general-case
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1c5cf1b3785c4e6dcd0b8549008861cb2c4e49ee;p=oota-llvm.git

Added the x86 INT instructions; both the special-case INT 3 and the general-case
INT i8.  These instructions are only for interpretation by disassemblers, not
for emission, so they do not as yet have patterns.
