[PATCH] D58102: Support X86 Control-flow Enforcement Technology (CET) in LLD

[Xiang Zhang via Phabricator via llvm-commits]

xiangzhangllvm updated this revision to Diff 191817.

Hi peter, this update will remove redundant .splt  in your upper ifunc test. 
The reason of redundant .splt is that we scan the IFUNC symbol after we collected the CET feature. So the splt was created first and without being removed after we found IFUNC.
Anyway this patch is just evade ifunc, I planed to hand ifunc+cet after this patch.
Thank your test! thank you too
