Subject: Deliver SIGTRAP, rather than SIGEMT, when a TADDccTV or TSUBccTV instruction
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=5a69559862a623003b3538e1fb82d24394f98fdc;p=openbsd

Deliver SIGTRAP, rather than SIGEMT, when a TADDccTV or TSUBccTV instruction
traps. Such instructions are deprecated in v9 (64-bit) code and should never
occur in real-life code. See v9 manual A.59 and A.60 for details.
