in an empty file, as we were overwriting the EOF token.  Overwriting an arbitrary token
never seems like a good idea in the error case.  This fixes a bug reported on the GCC
list :)

Add assembler dialect attribute in asm parser which lets target specific asm parser change dialect on the fly.

[asan] fix the wrong __WORDSIZE definition on Win x64, add ASAN_INTERFACE_FUNCTION_ATTRIBUTE. Patch by timurrrr@google.com

Splitting test case for Python synthetic children: part 1 test is only testing the synthetic children feature itself. More test cases will be commited for individual STL containers

Found and fixed bug in personality function:  Don't dive into the action table if the action entry is zero.

This commit provides a new default summary for Objective-C boolean variables, which shows YES or NO instead of the character value. A new category named objc is added to contain this summary provider. Any future Objective-C related formatters would probably fit here

llvm-svn: 149388

This fixes the case where Clang would output:
 error: format specifies type 'wchar_t *' (aka 'wchar_t *')

ArgTypeResult::getRepresentativeTypeName needs to take into account
that wchar_t can be a built-in type (as opposed to in C, where it is a
typedef).

Such a dead code elimination can remove redundant stores to arrays. It can also
eliminate calculations where the results are stored to memory but where they are
overwritten before ever being read. It may also fix bugs like:

This commit just adds a sceleton without any functionality.

If anybody is interested to learn about polyhedral optimizations this would be
a good task. Well definined, self contained and pretty simple. Ping me if you
want to start and you need some pointers to get going.

It is only needed for PoCC. We may update our openscop support which is
expected to be wider used. If this is the case we could automatically build
openscop.

As we now have a scheduler that works, I do not believe a lot of people need
PoCC right ahead. People who want to do an in depth investigation of the
different schedulers can install it as well manually.

unspecified unless the pointers are equal; therefore, such a comparison is not
a constant expression unless the pointers are equal.

ConstantDataArray::getString instead.

ConstantDataArray::getString instead.

Many instances of ConstantArray::get() could be moved to 
use more efficient ConstantDataArray methods that avoid a ton
of intermediate Constant*'s for each element (e.g. 
GetConstantArrayFromStringLiteral).  I don't plan on doing this
in the short-term though.

llvm-svn: 149363

with recent changes, ConstantArray is never a "string".  Remove the associated
methods and constant fold the clients to false.

llvm-svn: 149362

update this to ConstantDataArray.  There are no tests and this isn't using the preferred functionality for ripping apart strings, so I have no way to test this.

This removes implicit assumption about the form of MI coming into regalloc. In particular, it should be independent of ProcessImplicitDefs which will eventually become a standard part of coming out of SSA--unless we simply can eliminate IMPLICIT_DEF completely. Current unit tests expose this once I remove incidental pass ordering restrictions.

This is not a final fix. Just a temporary workaround until I figure out the right way.

Don't warn about -Wshorten-64-to-32 in unreachable code.  Fixes <rdar://problem/10759934>.  Apparently this is a common idiom in Linux (among other places).

Also cleaned up some shutdown delays.

eliminate the last uses of GetConstantStringInfo from this file, I didn't realize I was that close...

llvm-svn: 149354

These are very useful for frontends and other utilities reasoning about
or selecting between triples.

dramatically more efficient than GetConstantStringInfo.
