Dmitri Gribenko	e3769d450b	Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID ... This is done to avoid odd test failures, like the one fixed in r171243. llvm-svn: 171246	2012-12-30 01:28:40 +00:00
Rafael Espindola	41852873f7	Don't merge two constants if we care about the address of both. ... 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. llvm-svn: 123584	2011-01-16 17:05:09 +00:00
