Eli Friedman 8e12298192 Add proper type-checking for pointer additiion; before, we were accepting 
addition with a pointer and an integer even when it didn't make sense.

Eli Friedman f2442dcc8d Fix support for _Bool bitfields. The issue is that the bitfield width 
used for _Bool is not the same as the primitive width (which for _Bool 
is 1 bit).  The load and store changes add some casts to make the 
types consistent.  The EmitLValue changes make sure that the pointer is 
of an appropriate type for loading the bitfield.

This isn't perfect, but it's an improvement, and getting everything 
right depends on actually laying out structs in an ABI-compliant way.

Bill Wendling d70febc73b On Darwin, the string header file isn't 64-bit clean. The use of 
"-Wshorten-64-to-32 -Werror" will cause a failure when compiling this complex
program:

#include <string>

class Path {
  mutable std::string path;
public:
  bool operator == (const Path &that) {
    return path == that.path;
  }
};

Using strcmp gets us past this annoying error.

Dale Johannesen e7f5bc2c3b Weak functions not declared non-throwing might be 
replaced at linktime with a body that throws, even
if the body in this file does not.  Make PruneEH
be more conservative in this case.

Eli Friedman d5a4838e3d Backout of codegen-based fix to PR2334; this has been fixed differently 
at the Sema layer.

llvm-svn: 51203
 2008-05-16 20:38:39 +00:00
Eli Friedman 928ab4d546 Sema-based fix for PR2334. The issue is that even if the two sides of 
the condidtional have compatible types, they are not necessarily the 
same type.  Therefore, we cast to the composite type.  As a hack, for 
the moment we assume that the composite type is the type of the 
left-hand expression; this isn't correct, but it's good enough for most 
purposes.

Ted Kremenek c812b23ce8 Cache leaks by the allocation site, not the leak location. 
llvm-svn: 51198
 2008-05-16 18:33:44 +00:00
Ted Kremenek 590abd363e Partitioned BugTypeCachedLocation::isCached() into two methods: one that accepts and ExplodedNode, and the other that accepts a ProgramPoint. The default behavior is to cache bug reports by the 
location they occur (the end node).  Subclasses can override this behavior by providing a different ProgramPoint.

Owen Anderson c7d6eceb69 Remove ADCE's ability to delete loops. This ability is now implemented in a 
safer manner by loop deletion.

Owen Anderson bdcf408d67 Move this test from ADCE to loop deletion, where it is more appropriate.

Owen Anderson ad5f211b48 Clean ups for loop deletion based on Chris' feedback. 
Also, use SCEV to determine the trip count of the loop, which is more powerful
and accurate that Loop::getTripCount.

llvm-svn: 51178
 2008-05-16 04:27:38 +00:00
Owen Anderson a74d72d01f Fix this test. It was testing broken behavior in that it required ADCE to eliminate 
a potentially infinite loop, which is undesirable.  Instead, test the LICM behavior
that we're really interested in.
