Use llvm::sys::fs::make_absolute to get an absolute path before
matching. Also, allow "." directories to enable testing. ".." is still
not supported, and will require crossing file system boundaries to
implement correctly.

This adds support for the PPC "wc" inline asm constraint (used for allocating
individual CR bits). Support for this constraint type was recently added to the
LLVM PowerPC backend. Although gcc does not currently support allocating
individual CR bits, this identifier choice has been coordinated with the gcc
PowerPC team, and will be marked as reserved for this purpose in the gcc
constraints.md file.
Prior to this change, none of the multi-character PPC constraints were handled
correctly (the '^' escape character was not being added as required by the
parsing code in LLVM). This should now be fixed. I'll add tests for these other
constraints as support is added for them in the backend.

Was r202442
There were two issues with the original patch that have now been fixed.
1. We were memset'ing over a FileEntry in a test case. After adding a
std::string to FileEntry, this still happened to not break for me.
2. I didn't pass the FileManager into the new compiler instance in
compileModule. This was hidden in some cases by the fact I didn't
clear the module cache in the test.
Also, I changed the copy constructor for FileEntry, which was memcpy'ing
in a (now) unsafe way.

A 'remark' is information that is not an error or a warning, but rather some
additional information provided to the user. In contrast to a 'note' a 'remark'
is an independent diagnostic, whereas a 'note' always depends on another
diagnostic.
A typical use case for remark nodes is information provided to the user, e.g.
information provided by the vectorizer about loops that have been vectorized.
This patch provides the initial implementation of 'remarks'. It includes the
actual definiton of the remark nodes, their printing as well as basic parameter
handling. We are reusing the existing diagnostic parameters which means a remark
can be enabled with normal '-Wdiagnostic-name' flags and can be upgraded to
an error using '-Werror=diagnostic-name'. '-Werror' alone does not upgrade
remarks.
This patch is by intention minimal in terms of parameter handling. More
experience and more discussions will most likely lead to further enhancements
in the parameter handling.
llvm-svn: 202475
Pass through the externally-visible names that we got from the VFS down
to FileManager, and test that this is the name showing up in __FILE__,
diagnostics, and debug information.
llvm-svn: 202442
Keep the copy constructor around, and add a FIXME that we should really
remove it as soon as we have C++11 std::map's emplace function.
llvm-svn: 202439
This cleans up some constructors that would not be safe once FileEntry
owns the storage for its name. These were already suspect, since they
wouldn't work if the FileEntry had an open file descriptor. The only
user for these constructors was in UniqueFileContainer, which wasn't a
very useful abstraction anyway. So it and UniqueDirContainer have been
replaced with std::map<UniqueID, *>.
This change should not affect anything outside the FileManager.

When true, sets the name of the file to be the name from
'external-contents'. Otherwise, you get the virtual path that the file
was looked up by. This will not affect any non-virtual paths, or fully
virtual paths (for which there is no reasonable 'external' name anyway).
The setting is available globally, but can be overriden on a per-file
basis.
The goal is that this setting will control which path you see in debug
info, diagnostics, etc. which are sensitive to which path is used. That
will come in future patches that pass the name through to FileManager.
llvm-svn: 202329
This allows the 'name' field to contain a path, like
{ 'type': 'directory',
'name': '/path/to/dir',
'contents': [ ... ] }
which not only simplifies reading and writing these files (for humans),
but makes it possible to easily modify locations via textual
replacement, which would not have worked in the old scheme.
E.g. sed s:<ROOT>:<NEW ROOT>

Most 64-bit targets define int64_t as long int, and AArch64 should
make same definition to follow LP64 model. In GNU tool chain, int64_t
is defined as long int for 64-bit target. So to get consistent with GNU,
it's better Changing int64_t from 'long long int' to 'long int',
otherwise clang will get different name mangling suffix compared with g++.
llvm-svn: 202004
Provides a way to create a virtual file system using a YAML file that
supports mapping a file to a path on an 'external' file system. The
external file system will typically be the 'real' file system, but for
testing it can be changed.
A future patch will add a clang option to allow the user to specify such
a file and overlay it, but for now this code is only exercised by the
unit tests.

This does;
- clang_tablegen() adds each tblgen'd target to global property CLANG_TABLEGEN_TARGETS as list.
- List of targets is added to LLVM_COMMON_DEPENDS.
- all clang libraries and targets depend on generated headers.
You might wonder this would be regression, but in fact, this is little loss.
- Almost all of clang libraries depend on tblgen'd files and clang-tblgen.
- clang-tblgen may cause short stall-out but doesn't cause unconditional rebuild.
- Each library's dependencies to tblgen'd files might vary along headers' structure.
It made hard to track and update *really optimal* dependencies.
Each dependency to intrinsics_gen and ClangSACheckers is left as DEPENDS.

Previously reverted in r201755 due to causing an assertion failure.
I've removed the offending assertion, and taught the CompilerInstance to
create a default virtual file system inside createFileManager. In the
future, we should be able to reach into the CompilerInvocation to
customize this behaviour without breaking clients that don't care.

Summary:
This removes the need to coerce UnknownABI to the default ABI (O32 for
MIPS32, N64 for MIPS64 [*]) in both MipsSubtarget and MipsAsmParser.
Clang has been updated to disable both possible default ABI's before enabling
the ABI it intends to use.
[*] N64 being the default for MIPS64 is not actually correct.
However N32 is not fully implemented/tested yet.
