Justin Bogner f42cbce2da Protect user-supplied runtime library functions in LTO ... Add user-supplied C runtime and compiler-rt library functions to llvm.compiler.used to protect them from premature optimization by passes like -globalopt and -ipsccp. Calls to (seemingly unused) runtime library functions can be added by -instcombine and instruction lowering. Patch by Duncan Exon Smith, thanks! Fixes <rdar://problem/14740087> llvm-svn: 194514		2013-11-12 21:44:01 +00:00
