Chandler Carruth 392357eea0 Rename a test case to a more generic name. This is a completely useless 
test, but David Sehr is looking at spiffing it up and adding some proper
tests for our alloca codegen.

Anna Zaks b60908db3a [analyzer] Add experimental "issue hash" to the plist diagnostic. 
CmpRuns.py can be used to compare issues from different analyzer runs.
Since it uses the issue line number to unique 2 issues, adding a new
line to the beginning of a file makes all issues in the file reported as
new. 

The hash will be an opaque value which could be used (along with the
function name) by CmpRuns to identify the same issues. This way, we only
fail to identify the same issue from two runs if the function it appears
in changes (not perfect, but much better than nothing).

Manman Ren 2cdc8afccf X86: optimize generated code for integer ABS 
This patch will generate the following for integer ABS:
      movl    %edi, %eax
      negl    %eax
      cmovll  %edi, %eax
INSTEAD OF
      movl    %edi, %ecx
      sarl    $31, %ecx
      leal    (%rdi,%rcx), %eax
      xorl    %ecx, %eax

There exists a target-independent DAG combine for integer ABS, which converts
integer ABS to sar+add+xor. For X86, we match this pattern back to neg+cmov. 
This is implemented in PerformXorCombine.

Anna Zaks a7dcc996a9 [analyzer] Fixit for r158136. 
I falsely assumed that the memory spaces are equal when we reach this
point, they might not be when memory space of one or more is stack or
Unknown. We don't want a region from Heap space alias something with
another memory space.

Chandler Carruth 48687a5a00 Fix many doxygen formatting errors. 
This patch affects docs only, and includes formatting changes only
(though those include some fixes for broken Doxygen markup that caused
some content to be missing from generated pages).  It avoids generating
many spurious pages such as
http://clang.llvm.org/doxygen/classRepresents.html, but likely not all
yet.

Patch by James Dennett.

Benjamin Kramer 5d4cff72b4 Reuse APInt's getNumWords, which gets rounding right (my ad-hoc solution missed it). 
llvm-svn: 158151
 2012-06-07 15:54:03 +00:00
Benjamin Kramer 6003ad5848 Plug a long standing memory leak in TemplateArgument. 
The integral APSInt value is now stored in a decomposed form and the backing
store for large values is allocated via the ASTContext. This way its not
leaked as TemplateArguments are never destructed when they are allocated in
the ASTContext. Since the integral data is immutable it is now shared between
instances, making copying TemplateArguments a trivial operation.

Currently getting the integral data out of a TemplateArgument requires creating
a new APSInt object. This is cheap when the value is small but can be expensive
if it's not. If this turns out to be an issue a more efficient accessor could
be added.

Anna Zaks 3563fde6a0 [analyzer] Anti-aliasing: different heap allocations do not alias 
Add a concept of symbolic memory region belonging to heap memory space.
When comparing symbolic regions allocated on the heap, assume that they
do not alias. 

Use symbolic heap region to suppress a common false positive pattern in
the malloc checker, in code that relies on malloc not returning the
memory aliased to other malloc allocations, stack.
