Bill Wendling 37b94c6b4e If the global variable is removed by the linker, then don't constant merge it ... with other symbols. An object in the __cfstring section is suppoed to be filled with CFString objects, which have a pointer to ___CFConstantStringClassReference followed by a pointer to a __cstring. If we allow the object in the __cstring section to be merged with another global, then it could end up in any section. Because the linker is going to remove these symbols in the final executable, we shouldn't bother to merge them. <rdar://problem/10564621> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@147899 91177308-0d34-0410-b5e6-96231b3b80d8		2012-01-11 00:13:08 +00:00

GlobalOpt.cpp	PR11705, part 2: globalopt shouldn't put inttoptr/ptrtoint operations into global initializers if there's an implied extension or truncation.	2012-01-05 23:03:32 +00:00
InlineAlways.cpp	Inlining and unrolling heuristics should be aware of free truncs.	2011-10-01 01:39:05 +00:00
Inliner.cpp	Refactor code from inlining and globalopt that checks whether a function definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. 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.) Found while looking at PR11180.	2011-10-20 05:23:42 +00:00
