Subject: [MachineInstrBundle] Actually set the PartialDeadDef flag only when the register
X-Git-Tag: llvmorg-3.9.0-rc1~7843
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ddad5aa15283b625ecc8fdd1934c3c809a7b107f;p=platform%2Fupstream%2Fllvm.git

[MachineInstrBundle] Actually set the PartialDeadDef flag only when the register
is defined!

The users were checking the proper thing (Defined + PartialDeadDef), but the
information may have been wrong for other use cases, so fix that.
