Subject: Do not set the `link' bit when branching to the first BB of a function, as it
X-Git-Tag: android-x86-6.0-r1~1003^2~54507
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=9c661c8e26e93cbc1080d881e422cbcb4ca02e7b;p=android-x86%2Fexternal-llvm.git

Do not set the `link' bit when branching to the first BB of a function, as it
will cause an infinite loop.  The link bit is only used for calling functions.
