Jordan Rose 4938f276a5 Remove some stray uses of <ctype.h> functions.

Jordan Rose a7d03840e6 Excise <cctype> from Clang (except clang-tblgen) in favor of CharInfo.h.
Nearly all of these changes are one-to-one replacements; the few that
aren't have to do with custom identifier validation.

Jordan Rose a2100d755a Pull Lexer's CharInfo table out for general use throughout Clang.
Rewriting the same predicates over and over again is bad for code size and
code maintainence. Using the functions in <ctype.h> is generally unsafe
unless they are specified to be locale-independent (i.e. only isdigit and
isxdigit).

The next commit will try to clean up uses of <ctype.h> functions within Clang.

Bill Schmidt 2fe4c67374 Enable -fno-altivec, -mno-altivec for PowerPC.
Introduces these negation forms explicitly and uses them to control a new
"altivec" target feature for PowerPC.  This allows avoiding generating
Altivec instructions on processors that support Altivec.

The new test case verifies that the Altivec "lvx" instruction is not
used when -fno-altivec is present on the command line.

Tim Northover 9bb857a4f1 Add support for AArch64 target.
In cooperation with the LLVM patch, this should implement all scalar front-end

This patch excludes the NEON support also reviewed due to an outbreak of
batshit insanity in our legal department. That will be committed soon bringing
the changes to precisely what has been approved.

Douglas Gregor 6ddfca91e0 Implement parsing, AST, (de-)serialization, and placeholder global
metadata for linking against the libraries/frameworks for imported
modules.

The module map language is extended with a new "link" directive that
specifies what library or framework to link against when a module is
imported, e.g.,

  link "clangAST"

or

  link framework "MyFramework"

Importing the corresponding module (or any of its submodules) will
eventually link against the named library/framework.

For now, I've added some placeholder global metadata that encodes the
imported libraries/frameworks, so that we can test that this
information gets through to the IR. The format of the data is still
under discussion.

Benjamin Kramer 256f1dd0fc Speed up looking up static diagnostic infos.
Instead of doing a binary search over the whole diagnostic table (which weighs
a whopping 48k on x86_64), use the existing enums to compute the index in the
table. This avoids loading any unneeded data from the table and avoids littering
CPU caches with it. This code is in a hot path for code with many diagnostics.

1% speedup on -fsyntax-only gcc.c, which emits a lot of warnings.

have been upgraded to errors should not be treated as "errors" in this sense.

This required manually correcting all of the incorrect main-module

Bill Schmidt cec4cb151a This patch adds alignment information for long double to the 64-bit PowerPC
ELF subtarget.

The existing description string is moved from PPC64TargetInfo to its
DarwinTargetInfo subclass, to avoid any changes to the Darwin ABI.
PPC64TargetInfo now has two possible description strings: one for FreeBSD,
which requires 8-byte alignment, and a default string that requires
16-byte alignment.

I've added a test for PPC64 Linux to verify the 16-byte alignment.  If
somebody wants to add a separate test for FreeBSD, that would be great.

Note that there is a companion patch to update the alignment information
in LLVM, which I am committing now as well.

may not really work. It's on by default, but can be turned off with a flag if
you think you know what you're doing.

This is placed under a flag ('-Wasm-operand-widths') and flag group ('-Wasm').

Derek Schuff a202096dc0 Add pnaclcall convention to Native Client targets.
Because PNaCl bitcode must be target-independent, it uses some
different bitcode representations from other targets (e.g. byval and
sret for structures). This means that without additional type
information, it cannot meet some native ABI requirements for some
targets (e.g. passing structures containing unions by value on
x86-64). To allow generation of code which uses the correct native
ABIs, we also support triples such as x86_64-nacl, which uses
target-dependent IR (as opposed to le32-nacl, which uses byval and
sret).

To allow interoperation between the two types of code, this patch adds
a calling convention attribute to be used in code compiled with the
target-dependent triple, which will generate code using the le32-style
bitcode. This calling convention does not need to be explicitly
supported in the backend because it determines bitcode representation
rather than native conventions (the backend just needs to undersand
how to handle byval and sret for the Native Client OS).

This patch implements __attribute__((pnaclcall)) to generate calls in
bitcode according to the le32 bitcode conventions, an attribute which
is accepted by any Native Client target, but issues a warning
otherwise.

Dmitri Gribenko f26054f0fb Enable comment parsing and semantic analysis to emit diagnostics. A few
diagnostics implemented -- see testcases.

I created a new TableGen file for comment diagnostics,
DiagnosticCommentKinds.td, because comment diagnostics don't logically
fit into AST diagnostics file.  But I don't feel strongly about it.

This also implements support for self-closing HTML tags in comment
lexer and parser (for example, <br />).

In order to issue precise diagnostics CommentSema needs to know the
declaration the comment is attached to.  There is no easy way to find a decl by 
comment, so we match comments and decls in lockstep: after parsing one
declgroup we check if we have any new, not yet attached comments.  If we do --
then we do the usual comment-finding process.

It is interesting that this automatically handles trailing comments.
We pick up not only comments that precede the declaration, but also
comments that *follow* the declaration -- thanks to the lookahead in
the lexer: after parsing the declgroup we've consumed the semicolon
and looked ahead through comments.

Added -Wdocumentation-html flag for semantic HTML errors to allow the user to 
disable only HTML warnings (but not HTML parse errors, which we emit as
warnings in -Wdocumentation).

Argyrios Kyrtzidis 6d7833f1b6 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.

Jordan Rose 6f524ac9f0 Emit -verify diagnostics even when we have a fatal error.
Previously we'd halt at the fatal error as expected, but not actually emit
any -verify-related diagnostics. This lets us catch cases that emit a
/different/ fatal error from the one we expected.

This is implemented by adding a "force emit" mode to DiagnosticBuilder, which
will cause diagnostics to immediately be emitted regardless of current
suppression. Needless to say this should probably be used /very/ sparingly.

John McCall 5fb5df9c83 Restructure how the driver communicates information about the
target Objective-C runtime down to the frontend:  break this
down into a single target runtime kind and version, and compute
all the relevant information from that.  This makes it
relatively painless to add support for new runtimes to the
compiler.  Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime.  This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.

As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.

Meador Inge cdc0057e3c 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.

Hal Finkel 8eb5928514 Add PPC support for translating gcc-style -mcpu options into LLVM -target-cpu options.
This functionality is based on what is done on ARM, and enables selecting PPC CPUs
in a way compatible with gcc's driver. Also, mirroring gcc (and what is done on x86),
-mcpu=native support was added. This uses the host cpu detection from LLVM
(which will also soon be updated by refactoring code currently in backend).

In order for this to work, the target needs a list of valid CPUs -- we now accept all CPUs accepted by LLVM.
A few preprocessor defines for common CPU types have been added.

Jordan Rose ccf43ca05c Add pedantic warning -Wempty-translation-unit (C11 6.9p1).
In standard C since C89, a 'translation-unit' is syntactically defined to have
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.

Benjamin Kramer 543036a447 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

Daniel Dunbar c7c0089b44 [Basic] Fix up DiagnosticBuilder::{FlushCounts,Emit} to be inline.
- This is much more important than it appears at first glance...

The intended design of DiagnosticBuilder was that it never escape and that all
its members would get lowered to registers by the compiler. By fixing Emit here,
the compiler can completely eliminate the DiagnosticBuilder object and never
need to push those registers back into it.

Unfortunately, Sema has broken DiagnosticBuilder in other ways (by introducing
SemaDiagnosticBuilder), so we don't get the fill impact of this, but it is still
good for 30k reduction in code size. I'll work on fixing the
SemaDiagnosticBuilder problems next.

Argyrios Kyrtzidis 969fdfddd2 [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.

This seems to negatively affect compile time onsome ObjC tests

everywhere. Now adding a new diagnostic requires a full rebuild

Chad Rosier 4c17fa7620 In r149662, setDiagnosticMapping was modified to not allow warnings mapped to
MAP_ERROR to be remapped to MAP_WARNING.  These new APIs are being added to 
allow the diagnostic mapping's "no Werror" bit to be set, and potentially 
downgrade anything already mapped to be a warning.

Douglas Gregor 3ec6663be0 Back out my heinous hack that tricked the module generation mechanism
into using non-absolute system includes (<foo>)...

... and introduce another hack that is simultaneously more heineous
and more effective. We whitelist Clang-supplied headers that augment
or override system headers (such as float.h, stdarg.h, and
tgmath.h). For these headers, Clang does not provide a module
mapping. Instead, a system-supplied module map can refer to these
headers in a system module, and Clang will look both in its own
include directory and wherever the system-supplied module map
suggests, then adds either or both headers. The end result is that
Clang-supplied headers get merged into the system-supplied module for
the C standard library.

As a drive-by, fix up a few dependencies in the _Builtin_instrinsics
module.

each of the targets. Use this for module requirements, so that we can
pin the availability of certain modules to certain target features,

available.

Use these feature names to provide a nearly-complete module map for
Clang's built-in headers. Only mm_alloc.h and unwind.h are missing,
and those two are fairly specialized at the moment. Finishes

Douglas Gregor a686e1b05d Introduce module attributes into the module map grammar, along with a
single attribute ("system") that allows us to mark a module as being a
"system" module. Each of the headers that makes up a system module is

warnings there.

If a module is being inferred for a framework, and that framework
directory is within a system frameworks directory, infer it as a
system framework.

Bob Wilson a7a61e2701 Make clz/ctz builtins defined for zero on ARM targets. rdar://10732455
ARM supports clz and ctz directly and both operations have well-defined
results for zero.  There is no disadvantage in performance to using the
defined-at-zero versions of llvm.ctlz/cttz intrinsics.  We're running into
ARM-specific code written with the assumption that __builtin_clz(0) == 32,
even though that value is technically undefined.  The code is failing now
because of llvm optimizations that are taking advantage of the undef
behavior (specifically svn r147255).  There's nothing wrong with that
optimization on x86 where any incorrect assumptions about __builtin_clz(0)
will quickly be exposed.  For ARM, though, optimizations based on that undef
behavior are likely to cause subtle bugs.  Other targets with defined-at-zero
clz/ctz support may want to override the default behavior as well.

Sebastian Pop 86500280c6 remove assertions in the Hexagon backend specific clang driver
Patch from Jyotsna Verma:

I have made the changes to remove assertions in the Hexagon backend
specific clang driver. Instead of asserting on invalid arch name, it has
been modified to use the default value.

I have changed the implementation of the CPU flag validation for the
Hexagon backend. Earlier, the clang driver performed the check and
asserted on invalid inputs. In the new implementation, the driver passes
the last CPU flag (or sets to "v4" if not specified) to the compiler (and
also to the assembler and linker which perform their own check) instead of
asserting on incorrect values. This patch changes the setCPU function for
the Hexagon backend in clang/lib/Basic/Targets.cpp which causes the
compiler to error out on incorrect CPU flag values.

Douglas Gregor 9dc3212f98 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.

Argyrios Kyrtzidis c137d0d62f [PCH] Fix reading from PCH of diagnostic pragmas.
In certain cases ASTReader would call the normal DiagnosticsEngine API to initialize
the state of diagnostic pragmas but DiagnosticsEngine would try to compare source locations
leading to crash because the main FileID was not yet initialized.

Yet another case of the ASTReader trying to use the normal APIs and inadvertently breaking
invariants. Fix this by having the ASTReader set up the internal state directly.

Douglas Gregor 935bc7a214 Make the loading of information attached to an IdentifierInfo from an
AST file more lazy, so that we don't eagerly load that information for
all known identifiers each time a new AST file is loaded. The eager
reloading made some sense in the context of precompiled headers, since
very few identifiers were defined before PCH load time. With modules,
however, a huge amount of code can get parsed before we see an
@import, so laziness becomes important here.

The approach taken to make this information lazy is fairly simple:
when we load a new AST file, we mark all of the existing identifiers
as being out-of-date. Whenever we want to access information that may
come from an AST (e.g., whether the identifier has a macro definition,
or what top-level declarations have that name), we check the
out-of-date bit and, if it's set, ask the AST reader to update the
IdentifierInfo from the AST files. The update is a merge, and we now
take care to merge declarations before/after imports with declarations
from multiple imports.

The results of this optimization are fairly dramatic. On a small
application that brings in 14 non-trivial modules, this takes modules
from being > 3x slower than a "perfect" PCH file down to 30% slower
for a full rebuild. A partial rebuild (where the PCH file or modules
can be re-used) is down to 7% slower. Making the PCH file just a
little imperfect (e.g., adding two smallish modules used by a bunch of
.m files that aren't in the PCH file) tips the scales in favor of the
modules approach, with 24% faster partial rebuilds.

This is just a first step; the lazy scheme could possibly be improved
by adding versioning, so we don't search into modules we already
searched. Moreover, we'll need similar lazy schemes for all of the
other lookup data structures, such as DeclContexts.

Bob Wilson 73a4deb33d Change __extension__ to disable only diagnostics controlled by -pedantic.
This changes clang to match GCC's behavior for __extension__, which temporarily
disables the -pedantic flag.  Warnings that are enabled without -pedantic
are not affected.  Besides the general goodness of matching GCC's precedent,
my motivation for this is that macros in the arm_neon.h header need to use
__extension__ to avoid pedantic complaints about their use of statement
expressions, yet we still want to warn about incompatible pointer arguments
for those macros.

for strings which are not recognized (yay!). Finally it replaces
ridiculous if-chains with switches that cover all enumerators.

The last change required adding several missing entries to the features
function. These were obvious on inspection. Yay for a pattern that gives
warnings when we miss one.

No new test cases yet, as I want to get the 64-bit errors working first.

it an error if a CPU is provided for a target that doesn't implement

the CPU parameter from the getDefaultFeatures method. This parameter was
always filled in with the same value as setCPU was called with, and at
this point every single target implementation that referenced the CPU
within this function has needed to store the CPU via setCPU anyways in
order to implement other interface points.

which is roughly generated by inspecting the behavior of a trunk build

in the script that generates these so that others can use it to append
more tests for more architectures, etc.

Douglas Gregor faeb1d4658 When an import statement fails to find a module in the module cache,
but there is a corresponding umbrella header in a framework, build the
module on-the-fly so it can be immediately loaded at the import
statement. This is very much proof-of-concept code, with details to be
fleshed out over time.

Douglas Gregor 4a69c2e6c5 Modules hide macro definitions by default, so that silly things like
include guards don't show up as macro definitions in every translation
unit that imports a module. Macro definitions can, however, be
exported with the intentionally-ugly #__export_macro__
directive. Implement this feature by not even bothering to serialize
non-exported macros to a module, because clients of that module need
not (should not) know that these macros even exist.

Argyrios Kyrtzidis 2797df6a24 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".

Argyrios Kyrtzidis 61ef3db222 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.

Argyrios Kyrtzidis 92a47bd997 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.

Douglas Gregor 925296b4c2 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.
