I'll fix the file contents in the next commit.
This pass is currently expanding the COPY and SUBREG_TO_REG pseudos. I
am going to add a hook so targets can expand more pseudo-instructions
after register allocation.
Many targets have pseudo-instructions that assist the register
allocator. They can be expanded after register allocation, before PEI
and PostRA scheduling.

(this is always the case for scalars), otherwise use the promoted result type.
Fix test/CodeGen/X86/vsplit-and.ll when promote-elements is enabled.
llvm-svn: 140464
When generating the trunc-store of i1's, we need to use the vector type and not
the scalar type.
This patch fixes the assertion in CodeGen/Generic/bool-vector.ll when
running with -promote-elements.

cannot be converted.
This is in preparation for overload resolution of initializer lists.
Currently, you will always get this message when you try to pass an init
list to an overloaded function.
llvm-svn: 140461
the information on to Sema. There's still an incorrectness in the way template instantiation
works now, but that is due to a far larger underlying representational problem.
Also add a test case for various list initialization cases of scalars, which test this
commit as well as the previous one.
llvm-svn: 140460
Allow empty initializer lists for scalars, which mean value-initialization.
Constant evaluation for single-element and empty initializer lists for scalars.
Codegen for empty initializer lists for scalars.
Test case comes in next commit.
llvm-svn: 140459
builds a semantic (structured) initializer list, just reports on whether it can match
the given list to the target type.
Use this mode for doing init list checking in the initial step of initialization, which
will eventually allow us to do overload resolution based on the outcome.

This fixes a few errors when parsing MFC code with clang.
BTW clang trunk is now about 5 patches away to be able the parse the default wizard-generated MFC project.

contents starting at an offset (2 separate methods). This helps
the scripting interface stay more natural by allowing both from
Python.
Added the ability to dump data with address annotations when
call SBData::GetDescription().
Hooked up the SBSection to the __repr__ so you can print section
objects from within python.
Improved the dumping of symbols from python.
Fixed the .i interface references which were set to "Relative to this Group"
which somehow included Jim's "lldb-clean" root directory in the path. The
interfaces are now in a folder called "interfaces" withing the Xcode API
subfolder.

SBModule supports an additional SBSection iteration, besides the original SBSymbol iteration.
Add docstrings and implement the two SBSection iteration protocols.
llvm-svn: 140449
- New SBSection objects that are object file sections which can be accessed
through the SBModule classes. You can get the number of sections, get a
section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object
This should get us a lot closer to being able to symbolicate using LLDB through
the public API.
llvm-svn: 140437
set a watchpoint Pythonically. If the find-and-watch-a-variable operation
fails, an invalid SBValue is returned, instead.
Example Python usage:
value = frame0.WatchValue('global',
lldb.eValueTypeVariableGlobal,
lldb.LLDB_WATCH_TYPE_READ|lldb.LLDB_WATCH_TYPE_WRITE)
Add TestSetWatchpoint.py to exercise this API.
We have 400 test cases now.

The token stream was not getting properly reset when leaving
ParseLexedMethodDef in some error cases. In the testcase, that caused later
accesses to the token stream to touch memory which had been freed as we
finished parsing the class definition. Major hat-tip to AddressSanitizer for
helping pinpoint the use-after-free, including the allocation and deallocation
points:

Math is hard, and isScaledConstantInRange() always returned false for
negative constants. It was doing unsigned division of negative numbers
before casting back to signed.

too long, so that the jump from the line above the bad line to the line after
ends up in the middle of the bad line instead. Added a workaround to lldb to just
continue to the end if we find ourselves stopped in the middle of some other line.

Modify Target::DeleteCurrentProcess() to use DisableAllWatchpointLocations(false) to
disable the watchpoint locations, instead of removing them between process instances.
