* Add a way to grab the target options from the LTO command line.Bill Wendling2012-08-06
| | | | | | | | | | When the command line target options were removed from the LLVM libraries, LTO lost its ability to specify things like `-disable-fp-elim'. Add this back by adding the command line variables to the `lto' project. <rdar://problem/12038729> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161353 91177308-0d34-0410-b5e6-96231b3b80d8
* Hack the hack. If we have a situation where an ASM object is defined but isn'tBill Wendling2012-04-02

The ASM parser should supply more information so that we know what type of object it is, and what attributes it should have. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153870 91177308-0d34-0410-b5e6-96231b3b80d8
* It could come about that we parse the inline ASM before we get a potentialBill Wendling2012-04-02

* Make some headway towards compiling all of LLVM.Bill Wendling2012-03-29
| | | | | | | | | | | | | | | | | | Module-level ASM may contain definitions of functions and globals. However, we were not telling the linker that these globals had definitions. As far as it was concerned, they were just declarations. Attempt to resolve this by inserting module-level ASM functions and globals into the '_symbol' set so that the linker will know that they have values. This gets us further towards our goal of compiling LLVM, but it still has problems when linking libLTO.dylib because of the `-dead_strip' flag that's passed to the linker. <rdar://problem/11124216> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153638 91177308-0d34-0410-b5e6-96231b3b80d8

* 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
