Benjamin Kramer d469274743 GlobalOpt: Be more aggressive about elminating side-effect free static dtors. ... GlobalOpt runs early in the pipeline (before inlining) and complex class hierarchies often introduce bitcasts or GEPs which weren't optimized away. Teach it to ignore side-effect free instructions instead of depending on other passes to remove them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150174 91177308-0d34-0410-b5e6-96231b3b80d8		2012-02-09 14:26:06 +00:00

This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.)
