Dan Gohman 221708d826 Make SCEVAddRecExpr's getType return a pointer type when the add
has a pointer member. This helps reduce unnecessary bitcasting
and uglygeps.

Dan Gohman ca19445d08 When doing address-mode sinking, expand the base register first, rather
than the scaled register. This makes it more likely that subsequent
AddrModeMatcher queries will match the new address the same way as the
old, instead of accidentally matching what had been the base register
as the new scaled register, and then failing to match the scaled register.
This fixes some problems with address-mode sinking multiple muls into a
block, which will be a lot more common with some upcoming
LoopStrengthReduction changes.

Chris Lattner 003b5c8472 give MCAsmInfo a 'has little endian' bit. This is unfortunate, but
I really want clients of the streamer to be able to say "emit this
64-bit integer" and have it get broken down right by the streamer.

I may change this in the future, we'll see how it works out.

John McCall 5d7aa7fa0a The type of a compound literal expression is not necessarily the same as the

Douglas Gregor accb183371 Introduce the notion of an "unexposed" declaration into the CIndex
API. This is a catch-all for any declaration known to Clang but not
specifically part of the CIndex API. We'll use the same approach with
expressions, statements, references, etc., as needed.

Dan Gohman d693472821 Add a new helper function to IVUsers for returning the "canonical"
form of an expression. This is the expression without the
post-increment adjustment made, which is useful in determining
which registers will be used by the expansion.

the two token accessor functions are declared consistently.

Douglas Gregor 4f46e789b3 Rework the CXSourceLocation and CXSourceRange APIs. They are now
opaque data structures accessed through the new functions
clang_getInstantiationLocation(), clang_getRangeStart(), and
clang_getRangeEnd(). The new API permits later extensions to introduce
new functions to allow CIndex clients to walk macro instantiations, if
we ever care.

Daniel Dunbar 3779e1f49a Initial cut at integrating compiler-rt (on Darwin) w/ clang build.
- compiler-rt should be checked out into $LLVM_SRC_ROOT/projects/compiler-rt.

 - On Darwin, this will automatically build the runtime libraries clang needs
   into $OBJROOT/lib/clang/<version>/darwin/...

 - The mechanism can easily support other platforms, and can eventually support
   multiple platforms once clang has some kind of configure process (for
   specifying the desired targets).

 - Feedback on the approach is welcome.

Sean Callanan a83fd7d52c Propagated the parser-side Lex function's declaration to
MCAsmParser, and changed the target-specific AsmParsers
to use it.

llvm-svn: 93900

Sean Callanan 686ed8d248 Added a Lex function to the AsmParser, to allow handling
of include directives to occur within the parser itself.
This will break the lexer's dependency on a SourceMgr as
input.

Douglas Gregor 6b8232ff82 Eliminate cursor kinds used to express definitions. Instead, provide
CIndex functions that (1) map from a reference or declaration to the
corresponding definition, if available, and (2) determine whether a
given declaration cursor is also a definition. This eliminates a lot
of duplication in the cursor kinds, and maps more closely to the Clang
ASTs.

This is another API + ABI breaker with no deprecation. Yay, progress.

Chris Lattner 4340cb3246 add an MCAsmStreamer::EmitFill specialization of EmitFill that

Jim Grosbach 04770f2aa1 For aligned load/store instructions, it's only required to know whether a
function can support dynamic stack realignment. That's a much easier question
to answer at instruction selection stage than whether the function actually
will have dynamic alignment prologue. This allows the removal of the
stack alignment heuristic pass, and improves code quality for cases where
the heuristic would result in dynamic alignment code being generated when
it was not strictly necessary.

Bob Wilson 586a9b08ce The change in r90189 adds a link in a directory outside the iPhone platform
directory when building the llvmCore_Embedded project.  Fix this by putting
the iPhone platform directory into DEST_DIR instead of DEST_ROOT.  I also
noticed what appears to be an unintentional use of DEVELOPER_BIN instead of
DEVELOPER_DIR, so I fixed that and changed to use DEVELOPER_DIR in some places
that were hardcoded to "Developer".  Finally, the other changes here allowed
some refactoring and simplification, which I have done.
