Chad Rosier 95cd27265e [driver, ms-inline asm] -fms-compatibility enables -fms-extensions, so this should enable
the AsmBlocks language extension as well.

Chad Rosier 636386753a [driver, ms-inline asm] Have -fms-extensions enable the AsmBlocks language
option.  MS-style inline asm can now be enabled by either -fasm-blocks or
-fms-extensions.

Chad Rosier c8e56e8931 [driver, ms-inline asm] MS-Style inline assembly is controlled by the
-fasm-blocks flag, not the -fms-extensions flag.

Richard Smith f89e2e2583 PR14049: Don't say "expanded from macro 'foo'" when 'foo' just happens to be
the LHS of a token paste. Use "expanded from here" instead when we're not sure
it's actually a macro.

Richard Smith aebee680b6 Simplify slightly by seperating out the responsibility for emission of a caret
diagnostic from the emission of macro backtraces. Incidentally, we now get the
displayed source location for a diagnostic and the location for the caret from
the same place, rather than computing them separately. No functionality change.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Argyrios Kyrtzidis f3d587ea7c Refactor recording the preprocessor conditional directive regions out of
PreprocessingRecord and into its own class, PPConditionalDirectiveRecord.

Decoupling allows a client to use the functionality of PPConditionalDirectiveRecord

Douglas Gregor fa686fb4ed Teach the serialized diagnostic writer to clone() itself, sharing
state so that all of the various clones end up rendering their
diagnostics into the same serialized-diagnostics file. This is
important when we actually want failures during module build to be
reported back to the translation unit that tried to import the
not-yet-built or out-of-date module. <rdar://problem/12565727>

Douglas Gregor 22103e3416 When we're emitting a diagnostic with a source location in an imported
module, provide a module import stack similar to what we would get for
an include stack, e.g.,

In module 'DependsOnModule' imported from build-fail-notes.m:4:
In module 'Module' imported from DependsOnModule.framework/Headers/DependsOnModule.h:1:
Inputs/Module.framework/Headers/Module.h:15:12: note: previous definition is here

Douglas Gregor af8f02634b When an error occurs while building a module on demand, provide "While
building module 'Foo' imported from..." notes (the same we we provide
"In file included from..." notes) in the diagnostic, so that we know
how this module got included in the first place. This is part of
<rdar://problem/12696425>.

Douglas Gregor 7a626570ef Keep track of modules that have failed to build. If we encounter an
import of that module elsewhere, don't try to build the module again:
it won't work, and the experience is quite dreadful. We track this
information somewhat globally, shared among all of the related
CompilerInvocations used to build modules on-the-fly, so that a
particular Clang instance will only try to build a given module once.

Fixes <rdar://problem/12552849>.

Argyrios Kyrtzidis 2bafa0076d [libclang] When caching code-completion results, pass the CachedCompletionAllocator
to the CodeCompletionTUInfo that is going to be used to get the results.

Previously we would use ASTUnit's CodeCompletionTUInfo which has its own allocator
that will go away when we reparse. That could result in a use-after-free bug when
getting the parent context name from a CodeCompletionString.

Addresses rdar://12568377.

Lang Hames 65992f454c Make -ffp-contract a codegen option, rather than a laguage option. This makes

Richard Smith 0b50cb79ad Add -cc1 option -fno-diagnostics-use-presumed-location, a handy mode for
working with preprocessed testcases. This causes source locations in

while still keeping the semantic effects of the line directives (entering and
leaving system-header mode, primarily).

Daniel Dunbar e2951f48bf Frontend: Add support for reading named pipes as the main file.

Richard Smith b1b0ab41e7 Use the individual -fsanitize=<...> arguments to control which of the UBSan

Richard Smith 52be619c84 Add -fsanitize=<sanitizers> argument to driver and frontend, and add
-fno-sanitize=<sanitizers> argument to driver. These allow ASan, TSan, and the
various UBSan checks to be enabled and disabled separately. Right now, the
different modes can't be combined, but the intention is that combining UBSan
and the other sanitizers will be permitted in the near future.

Currently, the UBSan checks will all be enabled if any of them is; that will be
fixed by the next patch.
