Sanjiv Gupta 562d68e8db Pointer width on targets like PIC16 is 16-bit, while the valid index size to GEP is only 32 or 64. So promote index to 32 in such cases.

Ted Kremenek 605fee8445 New static analyzer check by Nikita Zhuk!
"The attached patch generates warnings of cases where an ObjC message is sent to
a nil object and the size of return type of that message is larger than the size
of void pointer. This may result in undefined return values as described in PR
2718.  The patch also includes test cases."

Daniel Dunbar ab7b2f5623 Set __PIC__ (more) correctly.
- Add -pic-level clang-cc option to specify the value for the define,
   updated driver to pass this.

 - Added __pic__

 - Added OBJC_ZEROCOST_EXCEPTIONS define while I was here (to match gcc).

Daniel Dunbar 3a148f2625 Driver: Forward remaining -f options to clang manually.
- Groups are really just intended to hold inherent structure of the
   options, not be abused for individual tool argument translation.

Fariborz Jahanian 9ecb84bb21 Now that we have __weak defined as attribute in all modes,

Daniel Dunbar d18049ab1d Driver: Manually translate a number of -f with no- variants options to
clang.
 - We will eventually want some more driver infrastructre for this
   probably.

 - For now, the clang-cc interface stays relatively the same, but we
   don't accept multiple instances anymore, or the [no-] variants
   directly.

Steve Naroff ebc790d4d8 Tweak Sema::ActOnInstanceMessage() to look for a class method when dealing with qualified id's. This change is motivated by our desire to not support the "Class<foo>" idiom. Note that the change makes perfect sense (since all ObjC classes are also id/instances).
This allow us to document a simple migration path...change "Class <foo>" to "id <foo>".

This effects: 
- <rdar://problem/6761939> TASK: File source change radars for "qualified Class" errors
- <rdar://problem/6761864> Protocol qualified Class is unsupported

Chris Lattner 0f98a286a3 implement rdar://6762183. I'm not sure if it is more insane that
GCC ignores macro definitions after \n's or that real code depends

2009-04-07 06:02:44 +00:00
Daniel Dunbar 15894b791b Various fixes to symbols used for Obj-C x86_64 metadata.
- Changed method names to match gcc (categories names still aren't
   mangled in).

 - Expose correct name for class and metadata symbols (although
   -fvisibility=hidden isn't yet correct).

 - Remove several things from llvm.used that didn't need to be there
   (I suspect this can still be trimmed).

 - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
   needed).

 - Hide EH type class info with -fvisibility=hidden

 - Change setGlobal[Option]Visibility to not change the visibility of
   functions with internal linkage.

2009-04-07 05:33:18 +00:00
Ted Kremenek 4d947facad Remove hack from LiveVariables analysis where variables whose address are taken
are considered 'live'. This hack isn't needed anymore because we have a
separation in the path-sensitive analyzer between variable names and bindings;
the analyzer can continue to reason about the storage of a variable after its
name is no longer directly referenced.  Now the live variables analysis literally means "is this name live".

Along this line, update the dead stores checker to explicitly look for variables
whose values have escaped.

Chris Lattner 33d840cc8f define __va_copy unconditionally, but va_copy only in c99 or non-ansi mode.

Chris Lattner c2d140156c The __weak and __strong defines are common to all darwin targets
and are even set in C mode.  As such, move them to Targets.cpp.

__OBJC_GC__ is also darwin specific, but seems reasonable to always
define it when in objc-gc mode.

This fixes rdar://6761450

Ted Kremenek c4c9ed0f9b Rewrite control-flow diagnostic generation "extensive" algorithm using "edge

Steve Naroff 837dc03222 Make casting 'super' a deprecated warning (instead of a hard error).
This will simplify clang adoption, and is probably better "etiquette" (since gcc has always accepted this idiom without warning). Once we are over the adoption hurdle, we can turn this into an error.

Daniel Dunbar f89733cfb8 Driver: Handle properly calling dsymutil when source input is
preceeded by a linker input flag.
 - <rdar://problem/6757236> clang should make a dSYM when going
   straight from source to binary

 - This still matches gcc, but the right way to solve this would be to
   detect the situation we care about (we are compiling from source
   and linking in one step), instead of looking at the suffix of the
   input file. The Tool doesn't quite have enough information to do
   this yet, however.

 - Also, find the suffix correctly.

Chris Lattner 49836b448e fix a FIXME, providing accurate source range info for DeclStmt's. The end
of the range is now the ';' location.  For something like this:

$ cat t2.c 

#define bool int
void f(int x, int y) {
bool b = !x && y;
}

We used to produce:
$ clang-cc t2.c -ast-dump 
typedef char *__builtin_va_list;

void f(int x, int y)
(CompoundStmt 0x2201f10 <t2.c:3:22, line:5:1>
  (DeclStmt 0x2201ef0 <line:2:14>                   <----
    0x2201a20 "int b =
      (BinaryOperator 0x2201ed0 <line:4:10, col:16> 'int' '&&'
        (UnaryOperator 0x2201e90 <col:10, col:11> 'int' prefix '!'
          (DeclRefExpr 0x2201c90 <col:11> 'int' ParmVar='x' 0x2201a50))
        (DeclRefExpr 0x2201eb0 <col:16> 'int' ParmVar='y' 0x2201e10))")


Now we produce:

$ clang-cc t2.c -ast-dump
typedef char *__builtin_va_list;

void f(int x, int y)
(CompoundStmt 0x2201f10 <t2.c:3:22, line:5:1>
  (DeclStmt 0x2201ef0 <line:2:14, line:4:17>         <------
    0x2201a20 "int b =
      (BinaryOperator 0x2201ed0 <col:10, col:16> 'int' '&&'

          (DeclRefExpr 0x2201c90 <col:11> 'int' ParmVar='x' 0x2201a50))
        (DeclRefExpr 0x2201eb0 <col:16> 'int' ParmVar='y' 0x2201e10))")

properly.

Similarly, be a bit smarter in our handling of ambiguities that occur
in Sema::getTypeName, to eliminate duplicate error messages about
ambiguous name lookup.

This eliminates two XFAILs in test/SemaCXX, one of which was crying
out to us, trying to tell us that we were producing repeated error
messages.

Douglas Gregor 2e0757f319 Give Type::getDesugaredType a "for-display" mode that can apply more
heuristics to determine when it's useful to desugar a type for display
to the user. Introduce two C++-specific heuristics:

  - For a qualified type (like "foo::bar"), only produce a new
    desugred type if desugaring the qualified type ("bar", in this
    case) produces something interesting. For example, if "foo::bar"
    refers to a class named "bar", don't desugar. However, if
    "foo::bar" refers to a typedef of something else, desugar to that
    something else. This gives some useful desugaring such as
    "foo::bar (aka 'int')".
  - Don't desugar class template specialization types like
    "basic_string<char>" down to their underlying "class
    basic_string<char, char_traits<char>, allocator<char>>, etc.";
    it's better just to leave such types alone. 

Update diagnostics.html with some discussion and examples of type
preservation in C++, showing qualified names and class template
specialization types.

Daniel Dunbar f524eff37d Add cocoa-pth.c test case, this got lost in shuffling PTH test cases.

Ted Kremenek 455de13de1 Re-enable PTH testing for cocoa.h and carbon.h. This tests that PTH works on
real-world header files and these tests have caught serious bugs in the past.

Daniel Dunbar e80bd1897c x86-32 Darwin ABI: Handle small structures correctly.
- Small structures are returned in a register if: 
    1. They fit nicely in a  register.
    2. All fields fit nicely in a register.
   (more or less)

 - We now pass the first 5000 ABITests if unions are disabled.

 - <rdar://problem/6497882> [irgen] x86-32 ABI compatibility with
   small structs

Daniel Dunbar 58e2971bb0 x86-32 Darwin ABI: Single element arrays can be part of "single
element structures", which have different ABI rules.
 - Current return-arguments-32 status is: 1 out of 1000 failures (-7)

 - Also, vectors inside "single element structs" require special
   handling.

Ted Kremenek 8b0dba358a Fix: <rdar://problem/6740387>. Sending nil to an object that returns a struct
should only be an error if that value is consumed. This fix was largely
accomplished by moving 'isConsumedExpr' back to ParentMap.

Chris Lattner 3088a31e96 remove ASTContext::buildObjCInterfaceType, which breaks canonical
types.  It is no longer needed now that the code generator 
re-lays-out interfaces if they are defines after being laid out
from a forward decl.

Ted Kremenek 0bb0909233 - Changed PathDiagnosticPiece::getLocation() to return a PathDiagnosticLocation
instead of a FullSourceLoc. This resulted in a bunch of small edits in various
  clients.
- Updated BugReporter to include an alternate PathDiagnostic generation
  algorithm for PathDiagnosticClients desiring more control-flow pieces.
