2013-05-06	Fix const merging when an alias of a const is llvm.used.	Rafael Espindola
	We used to disable constant merging not only if a constant is llvm.used, but also if an alias of a constant is llvm.used. This change fixes that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181175 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-30	Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ↵	Dmitri Gribenko
	ModuleID This is done to avoid odd test failures, like the one fixed in r171243. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171246 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-16	Don't merge two constants if we care about the address of both.	Rafael Espindola
	This fixes the original testcase in PR8927. It also causes a clang binary built with a patched clang to increase in size by 0.21%. We can probably get some of the size back by writing a pass that detects that a global never has its pointer compared and adds unnamed_addr to it (maybe extend global opt). It is also possible that there are some other cases clang could add unnamed_addr to. I will investigate extending globalopt next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123584 91177308-0d34-0410-b5e6-96231b3b80d8
