Douglas Gregor 250ffb1fcb When we're deserializing a template parameter declaration, temporarily
use the translation unit as its declaration context, then deserialize
the actual lexical and semantic DeclContexts after the template
parameter is complete. This avoids problems when the DeclContext
itself (e.g., a class template) is dependent on the template parameter
(e.g., for the injected-class-name).

Johnny Chen 930e3ad51e Add a test case ProcessAPITestCase.test_remote_launch() which tests SBProcess.RemoteLaunch()
API with a process not in eStateConnected, and checks that the remote launch failed.

Modify SBProcess::RemoteLaunch()/RemoteAttachToProcessWithID()'s log statements to fix a
crasher when logging is turned on.

Jakob Stoklund Olesen 4b598e156a Compute the constraints for global live range splitting from an interference pattern.
This simplifies the code and makes it faster too.

The interference patterns are saved for each candidate register. It will be
reused for actually executing the split. Work in progress.

Greg Clayton fc7117ae93 Added a DynamicLoaderStatic plug-in that will act as a static dynamic loader.
It will just load all files exactly where the files state they are (file
addresses == load addresses). This is used when the llvm::Triple::OSType is
set to llvm::Triple::UnknownOS or llvm::Triple::NoOS.

Argyrios Kyrtzidis 11e6f0a6c3 Currently we can only remap a file by creating a MemoryBuffer and replacing the file contents with it.
Allow remapping a file by specifying another filename whose contents should be loaded if the original
file gets loaded. This allows to override files without having to create & load buffers in advance.

high spill weight. Such a range should not be spilled.

Douglas Gregor 8c2d3f4248 After an error of any kind has occurred, don't assert when attempting
to find the instantiated declaration within a template instantiation
fails to do so. It's likely that the original instantiation got
dropped due to instantiation failures, which doesn't actually break
the invariants of the AST. This eliminates a number of
crash-on-invalid failures, e.g., PR9300.

Benjamin Kramer dfb0ad30a8 raw_ostream: while it is generally desirable to do larger writes, it can lead to
inefficient file system buffering if the writes are not a multiple of the desired
buffer size. Avoid this by limiting the large write to a multiple of the buffer
size and copying the remainder into the buffer.

Thanks to Dan for pointing this out.

Jakob Stoklund Olesen b8e6fdc23c Renumber slot indexes locally when possible.
Initially, slot indexes are quad-spaced. There is room for inserting up to 3
new instructions between the original instructions.

When we run out of indexes between two instructions, renumber locally using
double-spaced indexes. The original quad-spacing means that we catch up quickly,
and we only have to renumber a handful of instructions to get a monotonic
sequence. This is much faster than renumbering the whole function as we did
before.

Devang Patel d3a6b0f184 Emit a stop point before a call expression so that debugger has some chance of getting some footing when user wants to stop at 2nd bar() in following expression when all function calls are inlined.
= bar() + ... + bar() + ...

clang keeps track of column numbers, so we could put location entries for all subexpressions but that will significantly bloat debug info in general, but a location for call expression is helpful here.

Jakob Stoklund Olesen 348d8e8ba6 Number SlotIndexes uniformly without looking at the number of defs on each instruction.
You can't really predict how many indexes will be needed from the number of
defs, so let's keep it simple.

Also remove an extra empty index that was inserted after each basic block. It
was intended for live-out ranges, but it was never used that way.
