Anton Korobeynikov 415c3dc501 Add MSP430 mem-mem insts support. Patch by Brian Lucas with some my refinements 
llvm-svn: 83811
 2009-10-11 23:03:28 +00:00
Chris Lattner 2c2deae5ac remove some harmful code that would turn an insertelement on an undef 
into a shuffle even if it was used by another insertelement.  If the
visitation order of instcombine was wrong, this would turn a chain of
insertelements into a chain of shufflevectors, which was quite painful.

Since CollectShuffleElements handles these cases, the code can just
be nuked.

Chris Lattner 1639234775 cleanup, no functionality change. 
llvm-svn: 83795
 2009-10-11 21:36:10 +00:00
Chris Lattner fd27f8a5b3 generalize a transformation even more: we don't care whether the 
input the the mul is a zext from bool, just that it is all zeros
other than the low bit.  This fixes some phase ordering issues
that would cause us to miss some xforms in mul.ll when the worklist
is visited differently.

llvm-svn: 83791
 2009-10-11 21:05:34 +00:00
Chris Lattner bb058d3a23 populate instcombine's initial worklist more carefully, causing 
it to visit instructions from the start of the function to the
end of the function in the first path.  This greatly speeds up
some pathological cases (e.g. PR5150).

Torok Edwin 8b3081350e Remove CleanupDbgInfo, instcombine does this and its not worth duplicating it 
here.

Torok Edwin 907ec36943 LICM shouldn't sink/delete debug information. Fix this and add a testcase. 
For now the metadata of sinked/hoisted instructions is still wrong, but that'll
be fixed when instructions will have debug metadata directly attached.

Benjamin Kramer 3ce29858e9 CMake mingw build fixes. 
- llvm's libs must be linked after clang's
- libLLVMSystem depends on psapi on win32 (get_system_libs has it)
- CIndex builds successfully on mingw now

Sebastian Redl 8046049942 This ought to complete exception spec support. Man, am I glad.

Sebastian Redl 4915e63d3b Test exception spec compatibility on return type and parameters. 
Along the way, use RequireCompleteType when testing exception spec types.
Separate all the ugly spec stuff into its own file.

Zhongxing Xu b8edf2a4dd Introduces a new BindingVal which combines direct and 
default binding for regions. This allows us to simply a lot of code. A
further simplification could be done is that many methods of
regionstore can only work on Store instead of GRState.

 2009-10-11 08:08:02 +00:00
Chris Lattner e374382b8f implement rdar://7293527, a trivial instcombine that llvm-gcc 
gets but clang doesn't, because it is implemented in GCC's
fold routine.

Chris Lattner 97b1405207 implement a transformation in jump threading that is currently 
done by condprop, but do it in a much more general form.  The
basic idea is that we can do a limited form of tail duplication
in the case when we have a branch on a phi.  Moving the branch
up in to the predecessor block makes instruction selection
much easier and encourages chained jump threadings.

llvm-svn: 83759
 2009-10-11 07:24:57 +00:00
Chris Lattner 4140d8bd5c another testcase jump threading shouldn't crash on.
