3af1c9d334 [mips] Use pristine object file while processing relocations.
Similar to ARM change r182800, dynamic linker will read bits/addends from
    the original object rather than from the object that might have been patched
    previously. For the purpose of relocations for MCJIT stubs on MIPS, we
    internally use otherwise unused MIPS relocations.
    
    The change also enables MCJIT unit tests for MIPS (EL/BE), and the following
    two tests now pass:
    
    - MCJITTest.return_global and
    - MCJITTest.multiple_functions.
    
    These issues have been tracked as Bug 16250.

5fa8186b8d Adding tests for DebugIR pass
- lit tests verify that each line of input LLVM IR gets a !dbg node and a
  corresponding entry of metadata that contains the line number 
- unit tests verify that DebugIR works as advertised in the interface
- refactored some useful IR generation functionality from the MCJIT unit tests
  so it can be reused

deda39dbdf [mips] Remove Triple:mips from SupportedArchs in MCJIT unittests
MIPS does not handle multiple relocations correctly, so two tests from the
unittests are expected to fail. These are:
 - MCJITTest.return_global and
 - MCJITTest.multiple_functions.

Until the multiple relocations are fixed, XFAIL the MCJIT unittests for
MIPS. This issue is tracked as Bug 16250.

453f4f0130 Use only explicit bool conversion operators
BitVector/SmallBitVector::reference::operator bool remain implicit since
they model more exactly a bool, rather than something else that can be
boolean tested.

The most common (non-buggy) case are where such objects are used as
return expressions in bool-returning functions or as boolean function
arguments. In those cases I've used (& added if necessary) a named
function to provide the equivalent (or sometimes negative, depending on
convenient wording) test.

One behavior change (YAMLParser) was made, though no test case is
included as I'm not sure how to reach that code path. Essentially any
comparison of llvm::yaml::document_iterators would be invalid if neither
iterator was at the end.

This helped uncover a couple of bugs in Clang - test cases provided for
those in a separate commit along with similar changes to `operator bool`
instances in Clang.

13a3cf1928 SectionMemoryManager shouldn't be a JITMemoryManager. Previously, the
EngineBuilder interface required a JITMemoryManager even if it was being used 
to construct an MCJIT. But the MCJIT actually wants a RTDyldMemoryManager. 
Consequently, the SectionMemoryManager, which is meant for MCJIT, derived 
from the JITMemoryManager and then stubbed out a bunch of JITMemoryManager 
methods that weren't relevant to the MCJIT.

This patch fixes the situation: it teaches the EngineBuilder that 
RTDyldMemoryManager is a supertype of JITMemoryManager, and that it's 
appropriate to pass a RTDyldMemoryManager instead of a JITMemoryManager if 
we're using the MCJIT. This allows us to remove the stub methods from 
SectionMemoryManager, and make SectionMemoryManager a direct subtype of 
RTDyldMemoryManager.

50be71d182 Fix MCJITCAPITest.cpp unit test on Windows.
MCJIT on Windows requires an explicit target triple with "-elf" appended to generate objects in ELF format.  The common test framework was setting up this triple, but it wasn't passed to the C API in the test.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181614 91177308-0d34-0410-b5e6-96231b3b80d8

0e1327e4aa This exposes more MCJIT options via the C API:
CodeModel: It's now possible to create an MCJIT instance with any CodeModel you like.  Previously it was only possible to 
create an MCJIT that used CodeModel::JITDefault.

EnableFastISel: It's now possible to turn on the fast instruction selector.

The CodeModel option required some trickery.  The problem is that previously, we were ensuring future binary compatibility in 
the MCJITCompilerOptions by mandating that the user bzero's the options struct and passes the sizeof() that he saw; the 
bindings then bzero the remaining bits.  This works great but assumes that the bitwise zero equivalent of any field is a 
sensible default value.

But this is not the case for LLVMCodeModel, or its internal equivalent, llvm::CodeModel::Model.  In both of those, the default 
for a JIT is CodeModel::JITDefault (or LLVMCodeModelJITDefault), which is not bitwise zero.

Hence this change introduces LLVMInitializeMCJITCompilerOptions(), which will initialize the user's options struct with
defaults. The user will use this in the same way that they would have previously used memset() or bzero(). MCJITCAPITest.cpp
illustrates the change, as does the comment in ExecutionEngine.h.

fbb662f840 Introduce llvm::sys::getProcessTriple() function.
In r143502, we renamed getHostTriple() to getDefaultTargetTriple()
as part of work to allow the user to supply a different default
target triple at configure time.  This change also affected the JIT.
However, it is inappropriate to use the default target triple in the
JIT in most circumstances because this will not necessarily match
the current architecture used by the process, leading to illegal
instruction and other such errors at run time.

Introduce the getProcessTriple() function for use in the JIT and
its clients, and cause the JIT to use it.  On architectures with a
single bitness, the host and process triples are identical.  On other
architectures, the host triple represents the architecture of the
host CPU, while the process triple represents the architecture used
by the host CPU to interpret machine code within the current process.
For example, when executing 32-bit code on a 64-bit Linux machine,
the host triple may be 'x86_64-unknown-linux-gnu', while the process
triple may be 'i386-unknown-linux-gnu'.

This fixes JIT for the 32-on-64-bit (and vice versa) build on non-Apple
platforms.

0b8c9a80f2 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.

927ba6a0b3 Moving SectionMemoryManager into RuntimeDyld and adding unit tests for it.
The SectionMemoryManager now supports (and requires) applying section-specific page permissions.  Clients using this memory manager must call either MCJIT::finalizeObject() or SectionMemoryManager::applyPermissions() before executing JITed code.

See r168718 for changes from the previous implementation.
