Benjamin Kramer de712b788b Make the visibility of LLVMPPCCompilationCallback work with GCC.
GCC warns about the attribute being ignored if it occurs after void*.
There seems to be some kind of incompatibility between clang and gcc here, but
I can't fathom who's right.

void* LLVM_LIBRARY_VISIBILITY foo(); // clang: hidden, gcc: default
LLVM_LIBRARY_VISIBILITY void *bar(); // clang: hidden, gcc: hidden
void LLVM_LIBRARY_VISIBILITY qux();  // clang: hidden, gcc: hidden

Rafael Espindola 91cbcbb909 Give these callbacks hidden visibility. It is better to not export them more
than we need to and some ELF linkers complain about directly accessing symbols
with default visibility.

Rafael Espindola 9b7d4004bc Don't make assumptions about the mangling of static functions in extern "C"
blocks. We still don't have consensus if we should try to change clang or
the standard, but llvm should work with compilers that implement the current
standard and mangle those functions.

Rafael Espindola 764993493c Don't asume that a static function in an extern "C" block will not be mangled.
Since functions with internal linkage don't have language linkage, it is valid
to overload them:

extern "C" {
       static int foo();
       static int foo(int);
}

So we mangle them.

Chandler Carruth 9fb823bbd4 Move all of the header files which are involved in modelling the LLVM IR
into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.

There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.

The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.

I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).

I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

Chandler Carruth ed0881b2a6 Use the new script to sort the includes of every file under lib.
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

Jeffrey Yasskin 3aa70b2c4f Teach PPC how to replaceMachineCodeForFunction correctly. (Fixes
JITTest.FunctionIsRecompiledAndRelinked.)

Jeffrey Yasskin e0d8e14e11 Change indirect-globals to use a dedicated allocIndirectGV. This lets us
remove start/finishGVStub and the BufferState helper class from the
MachineCodeEmitter interface.  It has the side-effect of not setting the
indirect global writable and then executable on ARM, but that shouldn't be
necessary.

Jeffrey Yasskin f2ad571443 * Move stub allocation inside the JITEmitter, instead of exposing a
way for each TargetJITInfo subclass to allocate its own stubs. This
means stubs aren't as exactly-sized anymore, but it lets us get rid of
TargetJITInfo::emitFunctionStubAtAddr(), which lets ARM and PPC
support the eager JIT, fixing http://llvm.org/PR4816.

* Rename the JITEmitter's stub creation functions to describe the kind
of stub they create. So far, all of them create lazy-compilation
stubs, but they sometimes get used when far-call stubs are needed.
Fixing http://llvm.org/PR5201 will involve fixing this.

Jeffrey Yasskin 19b48370fb Allow more than one stub to be being generated at the same time.
It's probably better in the long run to replace the
indirect-GlobalVariable system. That'll be done after a subsequent
patch.

Torok Edwin fbcc663cbf llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

Torok Edwin 56d0659726 assert(0) -> LLVM_UNREACHABLE.
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

Chris Lattner 919ad97c01 JITEmitter.cpp was trying to sync the icache for function stubs, but
was actually passing a completely incorrect size to sys_icache_invalidate.
Instead of having the JITEmitter do this (which doesn't have the correct 
size), just make the target sync its own stubs.

Chris Lattner 09fecf9a47 this is an initial patch to switch the ppc64 jit over to working in PIC mode,

Evan Cheng f6acb34d23 - Refactor the code that resolve basic block references to a TargetJITInfo
method.
- Added synchronizeICache() to TargetJITInfo. It is called after each block
  of code is emitted to flush the icache. This ensures correct execution
  on targets that have separate dcache and icache.
- Added PPC / Mac OS X specific code to do icache flushing.

byte format.  This doesn't work when using the code emitter in a cross target

isn't a current problem, but if we ever start emitting .o files, it would be.
