Simplify the computation of undefined symbols. Instead of walking
...
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 :-)

Add a special streamer to libLTO that just records symbols definitions and

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 :-)

This patch lets LLDB build as an LLVM subproject. LLDB is not built in
...
parallel with the rest of the tools directory as it depends on Clang.
This patch was first applied in r125956 and subsequently reverted in
r125964 as it broke in-tree builds. Makefile.rules was fixed up in
r126070 to handle missing optional directories for the in-tree case,
so it should be safe now to bring this patch back in.
