Ted Kremenek 015c3561ad Use EvalSummary to process message expressions, thereby unifying the checker 
logic for function calls and message expressions.

Use the following heuristic to infer "allocating" instance methods:

  [ClassName classWithXXX]  allocates an object
  
Update testcase to reflect this heuristic.

Dan Gohman 38dc08f36f Instead of enumerating each opcode that isn't handled that 
ComputeMaskedBits handles, just use a 'default:'. This avoids
TargetLowering's list getting out of date with SelectionDAG's.

 2008-05-05 20:51:58 +00:00
Chris Lattner 8ed8e3d0e6 Fix a crash when threading a block that includes a MRV call result. 
DemoteRegToStack doesn't work with MRVs yet, because it relies on the
ability to load/store things.

This fixes PR2285.

properties declared in the protocol.

llvm-svn: 50662
 2008-05-05 18:51:55 +00:00
Ted Kremenek 627c3074dd Improve leak diagnostics to not report a leak on the same line where 
the object was last used.  This can be confusing to users.

For example:

 // 'y' is leaked
x = foo(y);

instead:

x = foo(y);
  // 'y' is leaked

Dan Gohman e3a63ba3cd Fix a bug in the ELF writer that caused it to produce malformed 
ELF headers. The ELF writer still isn't generally usable though.

llvm-svn: 50652

Dan Gohman 6fd71c6512 Use a dedicated IsLinux flag instead of an ELFLinux TargetType.

 2008-05-05 16:11:31 +00:00
Ted Kremenek db04a9e967 When reporting branch conditions that evaluate to an uninitialized value, 
highlight the most nested subexpression that appears most responsible (giving
the user better diagnostic feedback).

Updated test cases to illustrate this feature.

Chris Lattner 3565c8e343 Neil pointed out that clang doesn't generate ranges from diagnostics 
related to pp-expressions.  Doing so is pretty simple and this
patch implements it, yielding nice diagnostics like:

t.c:2:7: error: division by zero in preprocessor expression
#if 1 / (0 + 0)
    ~ ^ ~~~~~~~
t.c:5:14: error: expected ')' in preprocessor expression
#if (412 + 42
     ~~~~~~~~^
t.c:5:5: error: to match this '('
#if (412 + 42
    ^
t.c:10:10: warning: left side of operator converted from negative value to unsigned: -42 to 18446744073709551574
#if (-42 + 0U) / -2
     ~~~ ^ ~~
t.c:10:16: warning: right side of operator converted from negative value to unsigned: -2 to 18446744073709551614
#if (-42 + 0U) / -2
    ~~~~~~~~~~ ^ ~~
