Refine SourceManager's isBeforeInTranslationUnit() cache to have more entries.
isBeforeInTranslationUnit() uses a cache to reduce the expensive work
to compute a common ancestor for two FileIDs. This work is very
expensive, so even caching the latest used FileIDs was a big win.
A closer analysis of the cache before, however, shows that the cache
access pattern would oscillate between a working set of FileIDs, and
thus caching more pairs would be profitable.
This patch adds a side table for extending caching. This side table
is bounded in size (experimentally determined in this case from
a simple Objective-C project), and when the table gets too large
we fall back to the single entry caching before as before.
On Sketch (a small example Objective-C project), this optimization
reduces -fsyntax-only time on SKTGraphicView.m by 5%. This is
for a project that is already using PCH.

Replace some typically large vectors with SmallVector.
This may seem counter-intuitive but the POD-like optimization helps when the
vectors grow into multimegabyte buffers. SmallVector calls realloc which knows
how to twiddle virtual memory bits and avoids large copies.

Fix -Wunused-comparison for comparisons in arguments to function-like macros.
Previously, -Wunused-comparison ignored comparisons in both macro bodies and
macro arguments, but we would still emit a -Wunused-value warning for either.
Now we correctly emit -Wunused-comparison for expressions in macro arguments.
Also, add isMacroBodyExpansion to SourceManager, to go along with
isMacroArgExpansion.

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.

Introduce a flag in SourceManager to treat non-system source files
as "volatile", meaning there's a high enough chance that they may
change while we are trying to use them.
This flag is only enabled by libclang.
Currently "volatile" source files will be stat'ed immediately
before opening them, because the file size stat info
may not be accurate since when we got it (e.g. from the PCH).
This avoids crashes when trying to reference mmap'ed memory
from a file whose size is not what we expect.
Note that there's still a window for a racing issue to occur
but the window for it should be way smaller than before.
We can consider later on to avoid mmap completely on such files.

Revert predefined decl tracking.
r158085 added some logic to track predefined declarations. The main reason we
had predefined declarations in the input was because the __builtin_va_list
declarations were injected into the preprocessor input. As of r158592 we
explicitly build the __builtin_va_list declarations. Therefore the predefined
decl tracking is no longer needed.

at least one "external-declaration", which is either a decl or a function
definition. In Clang the latter gives us a declaration as well.
The tricky bit about this warning is that our predefines can contain external
declarations (__builtin_va_list and the 128-bit integer types). Therefore our
AST parser now makes sure we have at least one declaration that doesn't come
from the predefines buffer.
Also, remove bogus warning about empty source files. This doesn't catch source
files that only contain comments, and never fired anyway because of our
predefines.

[PCH] When validating that the files coming from PCH did not change, also
validate that we didn't override the contents of any of such files.
If this is detected, emit a diagnostic error and recover gracefully
by using the contents of the original file that the PCH was built from.

SourceManager: Vectorize ComputeLineNumbers for SSE2.
This method is very hot, it is called when emitting diagnostics, in -E mode
and for many #pragma handlers. It scans through the whole source file to
count newlines, records and caches them in a vector.
The speedup from vectorization isn't very large, as we fall back to bytewise
scanning when we hit a newline. There might be a way to avoid leaving the sse
loop but everything I tried didn't work out because a call to push_back
clobbers xmm registers.
About 2% speedup on average on "clang -E > /dev/null" of all .cpp files in
clang's lib/Sema.

[PCH] Recover gracefully if the ASTReader detects that a file is different
from the one stored in the PCH/AST, while trying to load a SLocEntry.
We verify that all files of the PCH did not change before loading it but this is not enough because:
- The AST may have been 1) kept around, 2) to do queries on it.
- We may have 1) verified the PCH and 2) started parsing.
Between 1) and 2) files may change and we are going to have crashes because the rest of clang
cannot deal with the ASTReader failing to read a SLocEntry.
Handle this by recovering gracefully in such a case, by initializing the SLocEntry
with the info from the PCH/AST as well as reporting failure by the ASTReader.

Implement (de-)serialization of the buffer contents for an overridden
file in the source manager. This allows us to properly create and use
modules described by module map files without umbrella headers (or
with incompletely umbrella headers). More generally, we can actually
build a PCH file that makes use of file -> buffer remappings, which
could be useful in libclang in the future.

Amend r138129 (reduction of SLocEntries) which introduced performance regression due
to increased calls to SourceManager::getFileID. (rdar://9992664)
Use a slightly different approach that is more efficient both in terms of speed
(no extra getFileID calls) and in SLocEntries reduction.
Comparing pre-r138129 and this patch we get:
For compiling SemaExpr.cpp reduction of SLocEntries by 26%.
For the boost enum library:
-SLocEntries -34% (note that this was -5% for r138129)
-Memory consumption -50%
-PCH size -31%
Reduced SLocEntries also benefit the hot function SourceManager::getFileID,
evident by the reduced "FileID scans".

Boost the efficiency of SourceManager::getMacroArgExpandedLocation.
Currently getMacroArgExpandedLocation is very inefficient and for the case
of a location pointing at the main file it will end up checking almost all of
the SLocEntries. Make it faster:
-Use a map of macro argument chunks to their expanded source location. The map
is for a single source file, it's stored in the file's ContentCache and lazily
computed, like the source lines cache.
-In SLocEntry's FileInfo add an 'unsigned NumCreatedFIDs' field that keeps track
of the number of FileIDs (files and macros) that were created during preprocessing
of that particular file SLocEntry. This is useful when computing the macro argument
map in skipping included files while scanning for macro arg FileIDs that lexed from
a specific source file. Due to padding, the new field does not increase the size
of SLocEntry.

Introduce SourceManager::getMacroArgExpandedLocation function.
If we pass it a source location that points inside a function macro argument,
the returned location will be the macro location in which the argument was expanded.
If a macro argument is used multiple times, the expanded location will
be at the first expansion of the argument.
e.g.
MY_MACRO(foo);
^
Passing a file location pointing at 'foo', will yield a macro location
where 'foo' was expanded into.
Make SourceManager::getLocation call getMacroArgExpandedLocation as well.

Revamp the SourceManager to separate the representation of parsed
source locations from source locations loaded from an AST/PCH file.
Previously, loading an AST/PCH file involved carefully pre-allocating
space at the beginning of the source manager for the source locations
and FileIDs that correspond to the prefix, and then appending the
source locations/FileIDs used for parsing the remaining translation
unit. This design forced us into loading PCH files early, as a prefix,
whic has become a rather significant limitation.
This patch splits the SourceManager space into two parts: for source
location "addresses", the lower values (growing upward) are used to
describe parsed code, while upper values (growing downward) are used
for source locations loaded from AST/PCH files. Similarly, positive
FileIDs are used to describe parsed code while negative FileIDs are
used to file/macro locations loaded from AST/PCH files. As a result,
we can load PCH/AST files even during parsing, making various
improvemnts in the future possible, e.g., teaching #include <foo.h> to
look for and load <foo.h.gch> if it happens to be already available.
This patch was originally written by Sebastian Redl, then brought
forward to the modern age by Jonathan Turner, and finally
polished/finished by me to be committed.

Keep track of which source locations are part of a macro argument
instantiation and improve diagnostics which are stem from macro
arguments to trace the argument itself back through the layers of macro
expansion.
This requires some tricky handling of the source locations, as the
argument appears to be expanded in the opposite direction from the
surrounding macro. This patch provides helper routines that encapsulate
the logic and explain the reasoning behind how we step through macros
during diagnostic printing.
This fixes the rest of the test cases originially in PR9279, and later
split out into PR10214 and PR10215.
There is still some more work we can do here to improve the macro
backtrace, but those will follow as separate patches.

Make the Preprocessor more memory efficient and improve macro instantiation diagnostics.
When a macro instantiation occurs, reserve a SLocEntry chunk with length the
full length of the macro definition source. Set the spelling location of this chunk
to point to the start of the macro definition and any tokens that are lexed directly
from the macro definition will get a location from this chunk with the appropriate offset.
For any tokens that come from argument expansion, '##' paste operator, etc. have their
instantiation location point at the appropriate place in the instantiated macro definition
(the argument identifier and the '##' token respectively).
This improves macro instantiation diagnostics:
Before:
t.c:5:9: error: invalid operands to binary expression ('struct S' and 'int')
int y = M(/);
^~~~
t.c:5:11: note: instantiated from:
int y = M(/);
^
After:
t.c:5:9: error: invalid operands to binary expression ('struct S' and 'int')
int y = M(/);
^~~~
t.c:3:20: note: instantiated from:
\#define M(op) (foo op 3);
~~~ ^ ~
t.c:5:11: note: instantiated from:
int y = M(/);
^
The memory savings for a candidate boost library that abuses the preprocessor are:
- 32% less SLocEntries (37M -> 25M)
- 30% reduction in PCH file size (900M -> 635M)
- 50% reduction in memory usage for the SLocEntry table (1.6G -> 800M)

Fix bug in SourceManager::getDecomposedInstantiationLocSlowCase.
It would add up relative (decomposed) offsets like in getDecomposedSpellingLocSlowCase, but while
it makes sense to preserve the offset among lexed spelling locations, it doesn't make
sense to add anything to the offset of the instantiation location. The instantiation
location will be the same regardless of the relative offset in the tokens that were
instantiated.
This bug didn't actually affect anything because, currently, in practice we never create macro
locations with relative offset greater than 0.

Teach SourceManager::getLocation() how to cope with a source file
whose inode has changed since the file was first created and that is
being seen through a different path name (e.g., due to symlinks or
relative path elements), such that its FileEntry pointer doesn't match
a known FileEntry pointer. Since this requires a system call (to
stat()), we only perform this deeper checking if we can't find the
file by comparing FileEntry pointers.
Also, add a micro-optimization where we don't bother to compute line
numbers when given the location (1, 1). This improves the
efficiency of clang_getLocationForOffset().

Partially revert Doug's PCH validation patch (r98585).
This patch completely defeated the "passing in a prestat'd size
to MemoryBuffer" optimization, leading to an extra fstat call for
every buffer opened, in order to find out if the datestamp and size
of the file on disk matches what is in the stat cache.
I fully admit that I don't completely understand what is going on here:
why punish code when a stat cache isn't in use? what is the point of a
stat cache if you have to turn around and stat stuff to validate it?
To resolve both these issues, just drop the modtime check and check the
file size, which is the important thing anyway. This should also resolve
PR6812, because presumably windows is stable when it comes to file sizes.
If the modtime is actually important, we should get it and keep it on the
first stat.
This eliminates 833 fstat syscalls when processing Cocoa.h, speeding up
system time on -Eonly Cocoa.h from 0.041 to 0.038s.

Implement -working-directory.
When -working-directory is passed in command line, file paths are resolved relative to the specified directory.
This helps both when using libclang (where we can't require the user to actually change the working directory)
and to help reproduce test cases when the reproduction work comes along.
--FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains
the working directory value if set).
--FileSystemOptions are passed around to various interfaces that perform file operations.
--Opening & reading the content of files should be done only through FileManager. This is useful in general since
file operations will be abstracted in the future for the reproduction mechanism.
FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same
FileManager but with different FileSystemOptions.

Introduce basic support for loading a precompiled preamble while
reparsing an ASTUnit. When saving a preamble, create a buffer larger
than the actual file we're working with but fill everything from the
end of the preamble to the end of the file with spaces (so the lexer
will quickly skip them). When we load the file, create a buffer of the
same size, filling it with the file and then spaces. Then, instruct
the lexer to start lexing after the preamble, therefore continuing the
parse from the spot where the preamble left off.
It's now possible to perform a simple preamble build + parse (+
reparse) with ASTUnit. However, one has to disable a bunch of checking
in the PCH reader to do so. That part isn't committed; it will likely
be handled with some other kind of flag (e.g., -fno-validate-pch).
As part of this, fix some issues with null termination of the memory
buffers created for the preamble; we were trying to explicitly
NULL-terminate them, even though they were also getting implicitly
NULL terminated, leading to excess warnings about NULL characters in
source files.

Introduce the notion of a single "delayed" diagnostic into the
Diagnostic subsystem, which is used in the rare case where we find a
serious problem (i.e., an inconsistency in the file system) while
we're busy formatting another diagnostic. In this case, the delayed
diagnostic will be emitted after we're done with the other
diagnostic. This is only to be used for fatal conditions detected at
very inconvenient times, where we can neither stop the current
diagnostic in flight nor can we suppress the second error.

Fix a longstanding (but previously unknown) bug in the lazy
deserialization of precompiled headers, where the deserialization of
the source location entry for a buffer (e.g., macro instantiation
scratch space) would overwrite a one-element FileID cache in the
source manager. When tickled at the wrong time, we would return the
wrong decomposed source location and eventually cause c-index-test to
crash.

Add a pretty horrible hack to prevent clang from crashing with inconsistent PCH
files.
- The issue is that PCH uses a stat cache, which may reference files which have
been deleted or moved. In such cases ContentCache::getBuffer was returning 0
but most clients are incapable of dealing with this (i.e., they don't).
For the time being, resolve this issue by just making up some invalid file
contents and. Eventually we should detect that we are in an inconsistent
situation and error out with a nice message that the PCH is out of date.

In SourceManager::isBeforeInTranslationUnit, if we are trying to compare two source locations with no common ancestor in the include stack, determine order by assuming memory buffers preceed files, and then that FileIDs are created in order.
The later assumption is patently false, but this was already broken -- this situation is conceptually impossible, my feeling is we should fix SourceManager and friends to make it impossible in practice as well. However, we need to fix PR5662 and perhaps some other things involving memory buffers first. In the short term I'm pretty sure this is reliable.
Chris, Argiris, is this going to break anything that wasn't already broken?

pass the reason for failure up from MemoryBuffer and report it
in diagnostics when we fail to open a file. This allows us to
report things like:
$ clang test.c -I.
test.c:2:10: fatal error: error opening file './foo.h': Permission denied
#include "foo.h"

Replace the -code-completion-dump option with
-code-completion-at=filename:line:column
which performs code completion at the specified location by truncating
the file at that position and enabling code completion. This approach
makes it possible to run multiple tests from a single test file, and
gives a more natural command-line interface.

Be more careful in our teardown of the PCHReader after deciding to

Load most of the source manager's information lazily from the PCH
file. In particular, only eagerly load source location entries for
files and for the predefines buffer. Other buffers and
macro-instantiation source location entries are loaded lazily.
With the Cocoa-prefixed "Hello, World", we only load 815/26555 source
location entities. This halves the amount of user time we spend in
this "Hello, World" program with -fsyntax-only (down to .007s).
This optimization is part 1 of 2 for the source manager. This
eliminates most of the user time in loading a PCH file. We still spend
too much time initialize File structures (especially in the calls to
stat), so we need to either make the loading of source location
entries for files lazy or import the stat cache from the PTH
implementation.

track "just a little more" location information for macro instantiations.
Now instead of just tracking the expansion history, also track the full
range of the macro that got replaced. For object-like macros, this doesn't
change anything. For _Pragma and function-like macros, this means we track
the locations of the ')'.
This is required for PR3579 because apparently GCC uses the line of the ')'
of a function-like macro as the location to expand __LINE__ to.

switch SourceManager from using an std::map and std::list of
ContentCache objects to using a densemap and list, and allocating
the ContentCache objects from a bump pointer. This does not speed
up or slow down things substantially, but gives us control over
their alignment.

Introduce a new PresumedLoc class to represent the concept of a location
as reported to the user and as manipulated by #line. This is what __FILE__,
__INCLUDE_LEVEL__, diagnostics and other things should follow (but not
dependency generation!).
This patch also includes several cleanups along the way:
- SourceLocation now has a dump method, and several other places
that did similar things now use it.
- I cleaned up some code in AnalysisConsumer, but it should probably be
simplified further now that NamedDecl is better.
- TextDiagnosticPrinter is now simplified and cleaned up a bit.
This patch is a prerequisite for #line, but does not actually provide
any #line functionality.

this massive patch introduces a simple new abstraction: it makes
"FileID" a concept that is now enforced by the compiler's type checker
instead of yet-another-random-unsigned floating around.
This is an important distinction from the "FileID" currently tracked by
SourceLocation. *That* FileID may refer to the start of a file or to a
chunk within it. The new FileID *only* refers to the file (and its
#include stack and eventually #line data), it cannot refer to a chunk.
FileID is a completely opaque datatype to all clients, only SourceManager
is allowed to poke and prod it.

SourceManager: Implement "lazy" creation of MemBuffers for source files.
- Big Idea:
Source files are now mmaped when ContentCache::getBuffer() is first called.
While this doesn't change the functionality when lexing regular source files,
it can result in source files not being paged in when using PTH.
- Performance change:
- No observable difference (-fsyntax-only/-Eonly) on Cocoa.h when doing
regular source lexing.
- No observable time difference (-fsyntax-only/-Eonly) on Cocoa.h when using
PTH. We do observe, however, a reduction of 279K in memory mapped source
code (3% reduction). The majority of pages from Cocoa.h (and friends) are
still being pulled in, however, because any literal will cause
Preprocessor::getSpelling() to be called (causing the source for the file to
get pulled in). The next possible optimization is to cache literal strings
in the PTH file to avoid the need for the original header sources entirely.
- Right now there is a preprocessor directive to toggle between "lazy" and
"eager" creation of MemBuffers. This is not permanent, and is there in the
short term to just test additional optimizations.

Misc changes to SourceManager::ContentCache:
- 'Buffer' is now private and must be accessed via 'getBuffer()'.
This paves the way for lazily mapping in source files on demand.
- Added 'getSize()' (which gets the size of the content without
necessarily accessing the MemBuffer) and 'getSizeBytesMapped()'.
- Modifed SourceManager to use these new methods. This reduces the
number of places that actually access the MemBuffer object for a file
to those that actually look at the character data.
These changes result in no performance change for -fsyntax-only on Cocoa.h.

Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfo
to whether the fileid is a 'extern c system header' in addition to whether it
is a system header, most of this is spreading plumbing around. Once we have that,
PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to
base the system header state on FileIDInfo instead of HeaderSearch. Finally,
in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness
of a file being entered can be set due to the #includer or the #includee.

* Make DiagClient optional for Diagnostic

* nothing crashes if one forgets to call setHeaderSearch() on

Hack ReadFileFast() to raise the threshold of memory mapped files (from 4->12 pages).
This is a temporary solution to avoid running out of file descriptors (which defaults to 256).
Need to benchmark to understand the speed benefit. If the benefit is small, the simple solution is to avoid memory mapping files. If the benefit is significant, more thought is necessary.

Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it. This follows the main
llvm tree, and allows the libraries to be built in parallel. The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in. This speeds
up parallel builds, particularly incremental ones.
