* Simplify the computation of undefined symbols. Instead of walkingRafael Espindola2011-03-18
| | | | | | | | | | | | | | | | | | | | | | | functions and initializers, just report the declarations present in the module. The motivation is to open the way for using the lazy module parsing, which should speed up clients that just want a symbol list (nm, ar). This is slightly less precise, but since both -strip-dead-prototypes and -globaldce are part of the standard pipeline, this shouldn't change the result for clang/dragonegg produced binaries. Any decl in an IL file was also put there because a FE expected it to be necessary, so this should not be a problem for "-O0 -emit-llvm". As a sanity check, I have bootstrapped clang on linux and built firefox on both linux and darwin. A clang bootstrap on darwin with LTO fails with or without this patch because, ironically, the linker doesn't like the combination of dead_strip and LTO when building libLTO.so :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127870 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a special streamer to libLTO that just records symbols definitions andRafael Espindola2011-03-02
| | | | | | | | | | | uses. The result produced by the streamer is used to give the linker more accurate information and to add to llvm.compiler.used. The second improvement removes the need for the user to add __attribute__((used)) to functions only used in inline asm. The first one lets us build firefox with LTO on Darwin :-) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126830 91177308-0d34-0410-b5e6-96231b3b80d8
