We cannot use "GetMaxU64Bitfield" for non-power-of-two sizes, so just use
the same code that handles N > 8 for these.

We can't insert an insertelement after an invoke. We would have to split a
critical edge. So when we see a phi node that uses an invoke we just give up.

other in memory.
The motivation was to get rid of truncate and shift right instructions that get
in the way of paired load or floating point load.
E.g.,
Consider the following example:
struct Complex {
float real;
float imm;
};
When accessing a complex, llvm was generating a 64-bits load and the imm field
was obtained by a trunc(lshr) sequence, resulting in poor code generation, at
least for x86.
The idea is to declare that two load instructions is the canonical form for
loading two arithmetic type, which are next to each other in memory.
Two scalar loads at a constant offset from each other are pretty
easy to detect for the sorts of passes that like to mess with loads.

- searches frames beginning from the current frame, stops when an equivalent context is found
- not using GetStackFrameCount() for performance reasons
- fixes TestInlineStepping (clang/gcc buildbots)

Add llvm.x86.* intrinsics for all of the Intel SHA Extensions instructions, as
well as tests. Also remove mayLoad and hasSideEffects, which can be inferred
from the instruction patterns.

Before (with column limit 60):
aaaaaaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaa >
> aaaaa);
After:
aaaaaaaaaaaaaaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaa >> aaaaa);
(Not sure how that could have stayed in that long without being
detected..)

AssignConvertType::IncompatibleVectors means the two types are in fact
compatible. :)
No testcase; I don't think the extra init list has any actual visible effect
other than making the resulting AST dump look a bit strange.
llvm-svn: 190845
Like any other type, an init list for a vector can have the same type as
the vector itself; handle that case.

Instead of defining the relevant functions inline, we now just keep the
declarations in the class itself. This makes the class declaration a lot
easier to read as all functions can be seen at once. We also use this
opportunity to privatize all functions not used in the public interface of the
class.

This sets the sectionChoice property for DefinedAtoms. The output section name
is derived by the property of the atom. This also decreases native file size.
Adds a test.

This has a side effect of preventing a crash, which occurs because we get a
property getter declaration, which is overriding but is declared inside
@protocol. Will file a bug about this inconsistency internally. Getting a
small test case is very challenging.

We need to escape filenames the same way in InclusionRewriter whether
UseLineDirective is true or false.

Let the module building code handle the case of overwriting an existing file
itself, so the existing locking infrastructure works correctly.

When a truncate node defines a legal vector type but uses an illegal
vector type, the legalization process was splitting the vector until
<1 x vector> type, but then it was failing to scalarize the node because
it did not know how to handle TRUNCATE.

The test builds an object file to be able to get into linking mode
with a valid obj file on the command-line. Using clang-cl for this,
which targets win32, caused problems on some buildbots, so just
use regular clang.
llvm-svn: 190829
Previously we would warn about unused arguments such as /MD when linking.
Clang already has logic to ignore compile-only options, e.g. for -D and -U.
This patch extends that to include clang-cl's compile-only options too.
Also, some clang-cl options should always be ignored. Doing this earlier
means they get ignored both for compilation and link-only invocations.
