2009-03-07 01:36:13 +00:00
Ted Kremenek 0666a6ce70 Selector: (changes made after discussing this more with Steve Naroff)
- Make Selector::getAsIdentifierInfo() private.  Using IdentifierInfo* in
  Selector is an implementation detail that clients shouldn't think about.
- Modify diagnostic emission in Sema::ProcessPropertyDecl to not use
  Selector::getAsIdentifierInfo() (which could crash when IdentifierInfo* is
  null) and instead use Selector::getAsString().
- Tidy up Selector::getAsString() implementation.

Chris Lattner 1a84994c46 allocate MultiKeywordSelector's out of a bump pointer allocator instead of malloc.
This has two advantages 1) no more leaking them, 2) fewer calls to malloc.

This changes us from calling malloc 3685/1390/883/2974/1185 times respectively on
16/20/24/28/32 byte objects when parsing cocoa.h with pth and -disable-free to
calling it 2816/1020/702/2903/1168 times each respectively.

Chris Lattner 5c3529634a implement support for propagating *features* down to the code generator
and defining target-specific macros based on them (like __SSE3__ and 
friends).  After extensive discussion with Daniel, this work will need
driver support, which will translate things like -msse3 into a -mattr 
feature.  Until this work is done, the code in clang.cpp is disabled and
the X86TargetInfo ctor still defaults to SSE2.  With these two things
changed, this code will work.  PR3634

Douglas Gregor 96977da72c Clean up and document code modification hints.
llvm-svn: 65641
2009-02-27 17:53:17 +00:00
Douglas Gregor 87f95b0a6a Introduce code modification hints into the diagnostics system. When we
know how to recover from an error, we can attach a hint to the
diagnostic that states how to modify the code, which can be one of:

  - Insert some new code (a text string) at a particular source
    location
  - Remove the code within a given range
  - Replace the code within a given range with some new code (a text
    string)

Right now, we use these hints to annotate diagnostic information. For
example, if one uses the '>>' in a template argument in C++98, as in
this code:

  template<int I> class B { };
  B<1000 >> 2> *b1;

we'll warn that the behavior will change in C++0x. The fix is to
insert parenthese, so we use code insertion annotations to illustrate
where the parentheses go:

test.cpp:10:10: warning: use of right-shift operator ('>>') in template
argument will require parentheses in C++0x
  B<1000 >> 2> *b1;
         ^
    (        )


Use of these annotations is partially implemented for HTML
diagnostics, but it's not (yet) producing valid HTML, which may be
related to PR2386, so it has been #if 0'd out.

In this future, we could consider hooking this mechanism up to the
rewriter to actually try to fix these problems during compilation (or,
after a compilation whose only errors have fixes). For now, however, I
suggest that we use these code modification hints whenever we can, so
that we get better diagnostics now and will have better coverage when
we find better ways to use this information.

This also fixes PR3410 by placing the complaint about missing tokens
just after the previous token (rather than at the location of the next
token).

Chris Lattner 810d330cd3 Fix a long standard problem with clang retaining "too much" sugar
information about types.  We often print diagnostics where we say 
"foo_t" is bad, but the user doesn't know how foo_t is declared 
(because it is a typedef).  Fix this by expanding sugar when present
in a diagnostic (and not one of a few special cases, like vectors).

Before:
t.m:5:2: error: invalid operands to binary expression ('typeof(P)' and 'typeof(F)')
 MAX(P, F);
 ^~~~~~~~~
t.m:1:78: note: instantiated from:
#define MAX(A,B)    ({ __typeof__(A) __a = (A); __typeof__(B) __b = (B); __a < __b ? __b : __a; })
                                                                             ^

After:
t.m:5:2: error: invalid operands to binary expression ('typeof(P)' (aka 'struct mystruct') and 'typeof(F)' (aka 'float'))
 MAX(P, F);
 ^~~~~~~~~
t.m:1:78: note: instantiated from:

Chris Lattner d2a2c13474 fix notes so that they are always filtered with the same logic
as the last non-note diagnostic that preceeded them.  This ensures
that diagnostics in main files which have notes with locations in 
system headers get all the bits and pieces emitted or not in a 
unit.  This fixes PR3215.

Chris Lattner 9dc9c206d3 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.

Ted Kremenek c8b740eade Add lightweight shim "clang::StatSysCallCache" that caches 'stat' system calls
for use by FileManager. FileManager now takes a StatSysCallCache* in its
constructor (which defaults to NULL). This will be used for evaluating whether
or not caching 'stat' system calls in PTH is a performance win. This shim adds
no observable performance impact in the case where the 'StatSysCallCache*' is
null.

DeclScope, during unqualified name lookup.

Chris Lattner f1ca7d3e02 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.

Implemented DiagCollector::IncludeInDiagnosticCounts() to return 'false' so that the batching of diagnostics for use with BugReporter doesn't mess up the count of real diagnostics.

Chris Lattner ad89ec013f Add a bit to IdentifierInfo that acts as a simple predicate which
tells us whether Preprocessor::HandleIdentifier needs to be called.
Because this method is only rarely needed, this saves a call and a
bunch of random checks.  This drops the time in HandleIdentifier 
from 3.52ms to .98ms on cocoa.h on my machine.

Ted Kremenek 52f73cad4a Fix: <rdar://problem/6510344> [pth] PTH slows down regular lexer considerably (when it has substantial work)
Changes to IdentifierTable:
- High-level summary: StringMap never owns IdentifierInfos.  It just
references them.
- The string map now has StringMapEntry<IdentifierInfo*> instead of
  StringMapEntry<IdentifierInfo>.  The IdentifierInfo object is
  allocated using the same bump pointer allocator as used by the
  StringMap.

Changes to IdentifierInfo:
- Added an extra pointer to point to the
  StringMapEntry<IdentifierInfo*> in the string map.  This pointer
  will be null if the IdentifierInfo* is *only* used by the PTHLexer
  (that is it isn't in the StringMap).

Algorithmic changes:
- Non-PTH case:
   IdentifierInfo::get() will always consult the StringMap first to
   see if we have an IdentifierInfo object.  If that StringMapEntry
   references a null pointer, we allocate a new one from the BumpPtrAllocator
   and update the reference in the StringMapEntry.
- PTH case:
   We do the same lookup as with the non-PTH case, but if we don't get
   a hit in the StringMap we do a secondary lookup in the PTHManager for
   the IdentifierInfo.  If we don't find an IdentifierInfo we create a
   new one as in the non-PTH case.  If we do find and IdentifierInfo
   in the PTHManager, we update the StringMapEntry to refer to it so
   that the IdentifierInfo will be found on the next StringMap lookup.
   This way we only do a binary search in the PTH file at most once
   for a given IdentifierInfo.  This greatly speeds things up for source
   files containing a non-trivial amount of code.

Performance impact:
   While these changes do add some extra indirection in
   IdentifierTable to access an IdentifierInfo*, I saw speedups even
   in the non-PTH case as well.

   Non-PTH: For -fsyntax-only on Cocoa.h, we see a 6% speedup.
   PTH (with Cocoa.h in token cache): 11% speedup.

   I also did an experiment where we did -fsyntax-only on a source file
   including a large header and Cocoa.h, but the token cache did not
   contain the larger header.  For this file, we were seeing a performance
   *regression* when using PTH of 3% over non-PTH.  Now we are seeing
   a performance improvement of 9%!

Tests:
   The serialization tests are now failing.  I looked at this extensively,
   and I my belief is that this change is unmasking a bug rather than
   introducing a new one.  I have disabled the serialization tests for now.

Chris Lattner d32480d3db 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.

Ted Kremenek a705b04d7f IdentifierInfo:
- IdentifierInfo can now (optionally) have its string data not be
  co-located with itself.  This is for use with PTH.  This aspect is a
  little gross, as getName() and getLength() now make assumptions
  about a possible alternate representation of IdentifierInfo.
  Perhaps we should make IdentifierInfo have virtual methods?

IdentifierTable:
- Added class "IdentifierInfoLookup" that can be used by
  IdentifierTable to perform "string -> IdentifierInfo" lookups using
  an auxilliary data structure.  This is used by PTH.
- Perform tests show that IdentifierTable::get() does not slow down
  because of the extra check for the IdentiferInfoLookup object (the
  regular StringMap lookup does enough work to mitigate the impact of
  an extra null pointer check).
- The upshot is that now that some IdentifierInfo objects might be
  owned by the IdentiferInfoLookup object.  This should be reviewed.

PTH:
- Modified PTHManager::GetIdentifierInfo to *not* insert entries in
  IdentifierTable's string map, and instead create IdentifierInfo
  objects on the fly when mapping from persistent IDs to
  IdentifierInfos.  This saves a ton of work with string copies,
  hashing, and StringMap lookup and resizing.  This change was
  motivated because when processing source files in the PTH cache we
  don't need to do any string -> IdentifierInfo lookups.
- PTHManager now subclasses IdentifierInfoLookup, allowing clients of
  IdentifierTable to transparently use IdentifierInfo objects managed
  by the PTH file.  PTHManager resolves "string -> IdentifierInfo"
  queries by doing a binary search over a sorted table of identifier
  strings in the PTH file (the exact algorithm we use can be changed
  as needed).

These changes lead to the following performance changes when using PTH on Cocoa.h:
- fsyntax-only: 10% performance improvement
- Eonly: 30% performance improvement

Ted Kremenek 763ea559ac 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.

2009-01-06 22:43:04 +00:00
Ted Kremenek 12c2af44e9 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.

  Line 10: duplicate interface declaration for category 'MyClass1' ('Category1')

instead of:

  Line 10: duplicate interface declaration for category 'MyClass1(Category1)'

I will fix this in a follow-up commit.

As part of this, I had to start switching stuff to use ->getDeclName() instead
of Decl::getName() for consistency.  This is good, but I was planning to do this

Chris Lattner 2b78690a9c Add the concept of "modifiers" to the clang diagnostic format
strings.  This allows us to have considerable flexibility in how
these things are displayed and provides extra information that
allows us to merge away diagnostics that are very similar.

Diagnostic modifiers are a string of characters with the regex
[-a-z]+ that occur between the % and digit.  They may 
optionally have an argument that can parameterize them.

For now, I've added two example modifiers.  One is a very useful
tool that allows you to factor commonality across diagnostics
that need single words or phrases combined.  Basically you can
use %select{a|b|c}4 with with an integer argument that selects
either a/b/c based on an integer value in the range [0..3).

The second modifier is also an integer modifier, aimed to help
English diagnostics handle plurality.  "%s3" prints to 's' if 
integer argument #3 is not 1, otherwise it prints to nothing.
I'm fully aware that 's' is an English concept and doesn't
apply to all situations (mouse vs mice).  However, this is very
useful and we can add other crazy modifiers once we add support
for polish! ;-)

I converted a couple C++ diagnostics over to use this as an
example, I'd appreciate it if others could merge the other
likely candiates.  If you have other modifiers that you want,
lets talk on cfe-dev.

Douglas Gregor 163c58502a Extend DeclarationName to support C++ overloaded operators, e.g.,
operator+, directly, using the same mechanism as all other special
names.

Removed the "special" identifiers for the overloaded operators from
the identifier table and IdentifierInfo data structure. IdentifierInfo
is back to representing only real identifiers.

Added a new Action, ActOnOperatorFunctionIdExpr, that builds an
expression from an parsed operator-function-id (e.g., "operator
+"). ActOnIdentifierExpr used to do this job, but
operator-function-ids are no longer represented by IdentifierInfo's.

Extended Declarator to store overloaded operator names. 
Sema::GetNameForDeclarator now knows how to turn the operator
name into a DeclarationName for the overloaded operator. 

Except for (perhaps) consolidating the functionality of
ActOnIdentifier, ActOnOperatorFunctionIdExpr, and
ActOnConversionFunctionExpr into a common routine that builds an
appropriate DeclRefExpr by looking up a DeclarationName, all of the
work on normalizing declaration names should be complete with this
commit.

2008-11-18 14:39:36 +00:00
Chris Lattner 8488c8297c This reworks some of the Diagnostic interfaces a bit to change how diagnostics
are formed.  In particular, a diagnostic with all its strings and ranges is now
packaged up and sent to DiagnosticClients as a DiagnosticInfo instead of as a 
ton of random stuff.  This has the benefit of simplifying the interface, making
it more extensible, and allowing us to do more checking for things like access
past the end of the various arrays passed in.

In addition to introducing DiagnosticInfo, this also substantially changes how 
Diagnostic::Report works.  Instead of being passed in all of the info required
to issue a diagnostic, Report now takes only the required info (a location and 
ID) and returns a fresh DiagnosticInfo *by value*.  The caller is then free to
stuff strings and ranges into the DiagnosticInfo with the << operator.  When
the dtor runs on the DiagnosticInfo object (which should happen at the end of
the statement), the diagnostic is actually emitted with all of the accumulated
information.  This is a somewhat tricky dance, but it means that the 
accumulated DiagnosticInfo is allowed to keep pointers to other expression 
temporaries without those pointers getting invalidated.

This is just the minimal change to get this stuff working, but this will allow
us to eliminate the zillions of variant "Diag" methods scattered throughout
(e.g.) sema.  For example, instead of calling:

  Diag(BuiltinLoc, diag::err_overload_no_match, typeNames,
       SourceRange(BuiltinLoc, RParenLoc));

We will soon be able to just do:

  Diag(BuiltinLoc, diag::err_overload_no_match)
      << typeNames << SourceRange(BuiltinLoc, RParenLoc));

This scales better to support arbitrary types being passed in (not just 
strings) in a type-safe way.  Go operator overloading?!

Douglas Gregor 993603d80d Add a new expression node, CXXOperatorCallExpr, which expresses a
function call created in response to the use of operator syntax that
resolves to an overloaded operator in C++, e.g., "str1 +
str2" that resolves to std::operator+(str1, str2)". We now build a
CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But
only for binary operators, where we actually implement overloading)

I decided *not* to refactor the current CallExpr to make it abstract
(with FunctionCallExpr and CXXOperatorCallExpr as derived
classes). Doing so would allow us to make CXXOperatorCallExpr a little
bit smaller, at the cost of making the argument and callee accessors
virtual. We won't know if this is going to be a win until we can parse
lots of C++ code to determine how much memory we'll save by making
this change vs. the performance penalty due to the extra virtual
calls.

Eli Friedman d50881c6a9 More fallout from r58501: primary fix is some more corrections to make
the types for size_t and ptrdiff_t more accurate.  I think all of these
are correct, but please compare the defines for __PTRDIFF_TYPE__ and 
__SIZE_TYPE__ to gcc to double-check; this particularly applies to 
those on BSD variants, since I'm not sure what they do here; I assume 
here that they're the same as on Linux.

Fixes wchar_t to be "int", not "unsigned int" (which I think is 
correct on everything but Windows).

Fixes ptrdiff_t to be "int" rather than "short" on PIC16; "short" is an 
somewhat strange choice because it normally gets promoted, and it's not 
consistent with the choice for size_t.

Sanjiv Gupta d79592448b Made the mechanism of defining preprocessor defs for maxint, ptrdiff_t, wchar
etc more generic. For some targets, long may not be equal to pointer size. For
example: PIC16 has int as i16, ptr as i16 but long as i32.

Also fixed a few build warnings in assert() functions in CFRefCount.cpp,
CGDecl.cpp, SemaDeclCXX.cpp and ParseDeclCXX.cpp.

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.

llvm-svn: 55101
2008-08-21 01:56:54 +00:00
Eli Friedman c968a6ab8e Initial implementation of Windows x86 target; at the moment, the only
difference from generic x86 is the defines.  The rest is non-trivial to 
implement.

I'm not planning on adding any more targets myself; if there are any 
targets anyone is currently using that are missing, feel free to add 
them, or ask me to add them.

This concludes the work I'm planning for the TargetInfo 
implementations at the moment; all the other issues with TargetInfo require
some API changes, and I haven't really thought it through.  Some of the
remaining issues: allowing targets to define size_t and wchar_t properly,
adding some sort of __builtin_type_info intrinsic so we can finish clang's 
limits.h and float.h and get rid of a massive number of macro 
definitions, allowing target-specific command-line options, allowing
target-specific defaults for certain command-line options like
-fms-extensions, exposing vector alignment outside of the description 
string, exposing endianness outside of the description string, allowing 
targets to expose special bit-field layout requirements, exposing some 
sort of custom hook for call generation in CodeGen, and adding CPU 
selection to control defines like __SSE__.

Eli Friedman 873f65afe8 First cut at OS detection, taking advantage of the new generic targets.
This approach allows adding OS-specific targets/defines/etc. without 
completely breaking unknown subtargets.  No new subtargets yet, although 
I plan to add x86-Linux soon.  Others can add targets that they use as 
needed; adding a new subtarget takes very little code.

Also does some fixups for description strings; a lot of them were 
unspecified.  I think all the ones I added are correct, but 
they're unverified; corrections are welcome.

but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
