Joerg Sonnenberger afb36fad99 Restore r125595 (reverted in r126336) with modifications:

Cameron Zwarich a62fc89a04 Merge information about the number of zero, one, and sign bits of live-out 
registers at phis. This enables us to eliminate a lot of pointless zexts during
the DAGCombine phase. This fixes <rdar://problem/8760114>.

llvm-svn: 126380

 2011-02-24 10:00:20 +00:00
Cameron Zwarich 97eb52da7b Add a mechanism for invalidating the LiveOutInfo of a PHI, and use it whenever 
a block is visited before all of its predecessors.

Richard Osborne bfa5cc0e08 Add XCore intrinsic for clre instruction. 
llvm-svn: 126322
 2011-02-23 18:52:05 +00:00
Richard Osborne 4995b05f56 Add llvm.xcore.waitevent intrinsic. The effect of this intrinsic is to enable 
events on the thread and wait until a resource is ready to event. The vector
of the resource that is ready is returned.

Stuart Hastings bf83659d11 Omit private_extern declarations of extern symbols; followup to 
r124468.  Patch by Rafael Avila de Espindola!

llvm-svn: 126297
 2011-02-23 02:27:05 +00:00
Nick Lewycky fc7222bfc4 Fix C++0x incompatibility. The signature of std::make_pair<> changes from: 
template <class T1, class T2> pair<T1,T2> make_pair(const T1&, const T2&);
to
  template <class T1, class T2> pair<V1, V2> make_pair(T1&&, T2&&);
so explicitly specifying the template arguments to make_pair<> is going to break
when C++0x rolls through. Replace them with equivalent std::pair<>. Patch by
James Dennett!

Devang Patel 9b4127349c Follow LLVM coding style. 
clang uses DBuilder, so it requries corresponding change.

llvm-svn: 126231
 2011-02-22 18:56:12 +00:00
Cameron Zwarich 7cf88763e0 MachineConstantPoolValues are not uniqued, so they need to be freed if they 
share entries. Add a DenseSet to MachineConstantPool for the MachineCPVs that
it owns.

This will hopefully fix the MC/ARM/elf-reloc-01.ll failure on the leaks bots.

 2011-02-22 08:54:30 +00:00

Devang Patel f3292b2196 Revert r124611 - "Keep track of incoming argument's location while emitting LiveIns." 
In other words, do not keep track of argument's location.  The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body.
This requires some coordination with debugger to get this working. 
 - The debugger needs to be aware of prolog_end attribute attached with line table entries.
 - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+)

Richard Osborne 1ae65c7cb8 Add XCore intrinsics for various instructions on ports.

Duncan Sands ecbbf0825b If the phi node was used by an unreachable instruction that ends up using 
itself without going via a phi node then we could return false here in
spite of making a change.  Also, tweak the comment because this method
can (and always could) return true without deleting the original phi node.
For example, if the phi node was used by a read-only invoke instruction
which is used by another phi node phi2 which is only used by and only uses
the invoke, then phi2 would be deleted but not the invoke instruction and
not the original phi node.

Chris Lattner 7e5d8aa6f9 Now that -loop-idiom uses TargetLibraryInfo properly, it doesn't 
need to be pulled out of the pass manager when the user specifies 
-fno-builtin.  It can intelligently determine which libcalls to
optimize based on what is enabled in TargetLibraryInfo.  This 
allows -fno-builtin-foo to work someday.
