LLVM 2.4 includes several major new capabilities:
MRVs got generalized to FCAs. getresult is gone, ret with multiple values - is gone.
-The most visible end-user change in LLVM 2.4 is that it includes many +optimizations and changes ot make -O0 compile times much faster. You should see +improvements on the order of 30% or more faster than LLVM 2.3. There are many +pieces to this change, described in more detail below. The speedups and new +components can also be used for JIT compilers that want fast compilation as +well.
-O0 compile times overall much faster
The biggest change to the LLVM IR is that Multiple Return Values (which +were introduced in LLVM 2.3) have been generalized to full support for "First +Class Aggregate" values in LLVM 2.4. This means that LLVM IR supports using +structs and arrays as values in a function. This capability is mostly useful +for front-end authors, who prefer to treat things like complex numbers, simple +tuples, dope vectors, etc as Value*'s instead of as a tuple of Value*'s or as +memory values.

Initial PIC16 port
Support the rest of the atomic __sync builtins
...
LLVM 2.4 also includes an initial port for the PIC16 microprocessor. This +is the LLVM targer that only has support for 8 bit registers, and a number of +other crazy constraints. While the port is still in early development stages, +it shows some interesting things you can do with LLVM.
LLVM 2.4 fully supports the llvm-gcc 4.2 front-end, and includes support -for the C, C++, Objective-C, Ada, and Fortran front-ends.
+LLVM fully supports the llvm-gcc 4.2 front-end, which marries the GCC +front-ends and driver with the LLVM optimizer and code generator. It currently +includes support for the C, C++, Objective-C, Ada, and Fortran front-ends.
