+commit 080fb498017d17af2e4d7563608c7d8a848f20da
+Author: Sanjoy Das <sanjoy at azulsystems.com>
+Date: Thu Jun 19 15:38:02 2014 -0700
+
+ Fix the --enable-shared build.
+
+ Currently a build configured with ./configure --enable-shared breaks
+ with an undefined "llvm::cl::parser<llvm::PassInfo
+ const*>::getOption(unsigned int) const" symbol when linking opt. This
+ body for this symbol gets emitted into Pass.o (along with the destructor
+ for PassNameParser), but gets linked into libLLVM-3.5svn.so with local
+ visibility, causing the link error.
+
+ This fix uses the existing EXTERN_TEMPLATE machinery to force a globally
+ visible definition for the functions in parser<const PassInfo *> into
+ Pass.o.

+ <longdescription>Low Level Virtual Machine (LLVM) is:
+ 1. A compilation strategy designed to enable effective program optimization
across the entire lifetime of a program. LLVM supports effective optimization
at compile time, link-time (particularly interprocedural), run-time and offline
(i.e., after software is installed), while remaining transparent to developers
and maintaining compatibility with existing build scripts.
+ 2. A virtual instruction set - LLVM is a low-level object code
representation that uses simple RISC-like instructions, but provides rich,
language-independent, type information and dataflow (SSA) information about
operands. This combination enables sophisticated transformations on object
code, while remaining light-weight enough to be attached to the executable.
This combination is key to allowing link-time, run-time, and offline
transformations.
+ 3. A compiler infrastructure - LLVM is also a collection of source code
that implements the language and compilation strategy. The primary components
of the LLVM infrastructure are a GCC-based C and C++ front-end, a link-time
optimization framework with a growing set of global and interprocedural
analyses and transformations, static back-ends for many popular (and some
obscure) architectures, a back-end which emits portable C code, and a
Just-In-Time compilers for several architectures.
+ 4. LLVM does not imply things that you would expect from a high-level
virtual machine. It does not require garbage collection or run-time code
generation (In fact, LLVM makes a great static compiler!). Note that optional
LLVM components can be used to build high-level virtual machines and other
systems that need these services.</longdescription>
