Following r168626, in class declaration or definition, there are a combination of syntactic locations
where C++11 attributes could appear, and among those the only valid location permitted by standard is
between class-key and class-name. So for those attributes appear at wrong locations, fixit is used to
move them to expected location and we recover by applying them to the class specifier.

updating them.

with respect to the lower "left-hand-side bitwidth" bits, even when negative);
see OpenCL spec 6.3j. This patch both implements this behaviour in the code
generator and "constant folding" bits of Sema, and also prevents tests
to detect undefinedness in terms of the weaker C99 or C++ specifications
from being applied.

This should make it slightly more readable as it more clearly separates
what happens where. No intended functional changes. More of this to
come..

This matches the test change done in clang at r171742. Without this,
clang-format would strip '@' characters and format e.g. '@interface' as
'interface'.
llvm-svn: 171743
Also set ObjC1 in the formatter tests.
The only effect of this flag in the lexer is that '@' now gets turned into
tok::at instead of tok::unknown.

peculiar headers under include/llvm.
This struct still doesn't make a lot of sense, but it makes more sense
down in TargetLowering than it did before.

already in a class, just inline the four of them. I suspect that this
class could be simplified some to not always keep distinct variables for
these things, but it wasn't clear to me how given the usage so I opted
for a trivial and mechanical translation.
This removes one of the two remaining users of a header in include/llvm
which does nothing more than define a 4 member struct.
llvm-svn: 171738
TargetTransformInfo rather than TargetLowering, removing one of the
primary instances of the layering violation of Transforms depending
directly on Target.
This is a really big deal because LSR used to be a "special" pass that
could only be tested fully using llc and by looking at the full output
of it. It also couldn't run with any other loop passes because it had to
be created by the backend. No longer is this true. LSR is now just
a normal pass and we should probably lift the creation of LSR out of
lib/CodeGen/Passes.cpp and into the PassManagerBuilder. =] I've not done
this, or updated all of the tests to use opt and a triple, because
I suspect someone more familiar with LSR would do a better job. This
change should be essentially without functional impact for normal
compilations, and only change behvaior of targetless compilations.
The conversion required changing all of the LSR code to refer to the TTI
interfaces, which fortunately are very similar to TargetLowering's
interfaces. However, it also allowed us to *always* expect to have some
implementation around. I've pushed that simplification through the pass,
and leveraged it to simplify code somewhat. It required some test
updates for one of two things: either we used to skip some checks
altogether but now we get the default "no" answer for them, or we used
to have no information about the target and now we do have some.
I've also started the process of removing AddrMode, as the TTI interface
doesn't use it any longer. In some cases this simplifies code, and in
others it adds some complexity, but I think it's not a bad tradeoff even
there. Subsequent patches will try to clean this up even further and use
other (more appropriate) abstractions.
Yet again, almost all of the formatting changes brought to you by
clang-format. =]

bogus comparison operands to default to eq/oeq. Fix that, fix a couple of
tests that accidentally passed and test for bogus comparison opeartors
explicitly.

This addresses llvm.org/PR14830.
Before:
unsigned Cost =
TTI.getMemoryOpCost(I->getOpcode(), VectorTy, SI->getAlignment(),
SI->getPointerAddressSpace());
CharSourceRange LineRange =
CharSourceRange::getTokenRange(TheLine.Tokens.front().Tok.getLocation(),
TheLine.Tokens.back().Tok.getLocation());
After:
unsigned Cost = TTI.getMemoryOpCost(I->getOpcode(), VectorTy,
SI->getAlignment(),
SI->getPointerAddressSpace());
CharSourceRange LineRange = CharSourceRange::getTokenRange(
TheLine.Tokens.front().Tok.getLocation(),
TheLine.Tokens.back().Tok.getLocation());
This required rudimentary changes to static initializer lists, but we
are not yet formatting them in a reasonable way. That will be done in a
subsequent patch.

This addresses llvm.org/PR14815.
To implement this I introduced a line type during parsing and moved the
definition of TokenType out of the struct for increased readability.
Should have done the latter in a separate patch, but it would be hard to
pull apart now.

This makes the loop vectorizer match the pattern followed by roughly all
other passses. =]
Notably, this header file was braken in several regards: it contained
a using namespace directive, global #define's that aren't globaly
appropriate, and global constants defined directly in the header file.
As a side benefit, lots of the types in this file become internal, which
will cause the optimizer to chew on this pass more effectively.
llvm-svn: 171723
This could be simplified further, but Hal has a specific feature for
ignoring TTI, and so I preserved that.
Also, I needed to use it because a number of tests fail when switching
from a null TTI to the NoTTI nonce implementation. That seems suspicious
to me and so may be something that you need to look into Hal. I worked
it by preserving the old behavior for these tests with the flag that
ignores all target info.

Absent a Contributor's License Agreement (CLA) with an LLVM legal entity and as
reviewed and agreed with Chris Lattner, add a patent license covering future
contributions from ARM until there is a CLA. This is to make explicit ARM's
grant of patent rights to recipients of LLVM containing ARM-contributed
material.

The case that we wanted to write a test for cannot happen, as the
UnwrappedLineParser already protects against it. Added an assert to
prevent regressions of that assumption.
llvm-svn: 171720
this patch brought to you by the tool clang-format.
I wanted to fix up the names of constructor parameters because they
followed a bit of an anti-pattern by naming initialisms with CamelCase:
'Tti', 'Se', etc. This appears to have been in an attempt to not overlap
with the names of member variables 'TTI', 'SE', etc. However,
constructor arguments can very safely alias members, and in fact that's
the conventional way to pass in members. I've fixed all of these I saw,
along with making some strang abbreviations such as 'Lp' be simpler 'L',
or 'Lgl' be the word 'Legal'.
However, the code I was touching had indentation and formatting somewhat
all over the map. So I ran clang-format and fixed them.
I also fixed a few other formatting or doxygen formatting issues such as
using ///< on trailing comments so they are associated with the correct
entry.
There is still a lot of room for improvement of the formating and
cleanliness of this code. ;] At least a few parts of the coding
standards or common practices in LLVM's code aren't followed, the enum
naming rules jumped out at me. I may mix some of these while I'm here,
but not all of them.

First check only wrapped with i==8, second wrapped at i==2,8,18,28,...
This fix restores the intended behavior: i==8,18,28,...
Found with -fsanitize=integer.
llvm-svn: 171718
We would format:
#define A \
int f(a); int i;
as
#define A \
int f(a);\
int i
The fix will break up macro definitions that could fit a line, but hit
the last column; fixing that is more involved, though, as it requires
looking at the following line.

I'm sorry for duplicating bad style here, but I wanted to keep
consistency. I've pinged the code review thread where this style was
reviewed and changes were requested.
llvm-svn: 171714
Previously, we'd format
int i;\
// comment
as
int i; // comment
The problem is that the escaped newline is part of the next token, and
thus the raw token text of the comment doesn't start with "//".

This c'tor takes the AttributeSet class as the parameter. It will eventually

with those attributes.
