generated files from a previous in-source builds.

Chris Lattner 67e70971cc fix PR6858: a dangling pointer use bug which was caused 
by switching CachedFunctionInfo from a std::map to a 
ValueMap (which is implemented in terms of a DenseMap).

DenseMap has different iterator invalidation semantics
than std::map.

This should hopefully fix the dragonegg builder.

llvm-svn: 101636
 2010-04-17 15:31:16 +00:00
Dan Gohman 21cea8ac2e Use const qualifiers with TargetLowering. This eliminates several 
const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

llvm-svn: 101635
 2010-04-17 15:26:15 +00:00
Dan Gohman 31ae586c74 Move per-function state out of TargetLowering subclasses and into 
MachineFunctionInfo subclasses.

Benjamin Kramer 95c7c427aa Add printName to DeclarationName which prints the human-readable name on a 
raw_ostream. Use it in getAsString and NamedDecl's raw_ostream operator.

llvm-svn: 101633
 2010-04-17 09:56:45 +00:00
Benjamin Kramer b11416d061 Add raw_ostream operators to NamedDecl for convenience. Switch over all users of getNameAsString on a stream. 
The next step is to print the name directly into the stream, avoiding a temporary std::string copy.

Chandler Carruth ca0a53ac52 Name these stub files consistently with the SPU and PPC targets' conventions. 
Also rename the classes appropriately. The CMake build already used these
names.

Chris Lattner 7f5088e6de a bunch of ssse3 instructions are misencoded to think they have an 
i8 field when they really do not.  This fixes rdar://7840289

llvm-svn: 101629
 2010-04-17 07:38:24 +00:00
Chris Lattner 7c4f14bf90 reenable r101565, removing a problematic assertion. 
CGSCC can delete nodes in regions of the callgraph that
have already been visited.  If new CG nodes are allocated
to the same pointer, we shouldn't abort, just handle it
correctly by assigning a new number.  This should restore
stability by removing invalidated pointers that *will* be
reused from the densemap in the iterator.

Evan Cheng 5fdb57cc10 Postra machine licm must add registers defined by loop invariants to *all* of 
the live-in sets of BBs in the loop. Otherwise later pass may end up using the
registers and override the invariant. rdar://7852937
No reasonablly sized test case possible.

Nick Lewycky 04b8eec241 Refresh this documentation. Things have changed a bit in the mean time: 
- LLVMgold.so --> libLLVMgold.so
 - the GCC LTO project is no longer 'upcoming'
 - document the plugin support for 'ar' and 'nm'

Chris Lattner b714a4b4a0 revert r101568, which miscompiles this testcase, distilled from ldecod:

Bob Wilson 59b70eacad Revise my previous change to ExpandBIT_CONVERT. I hadn't realized that this 
may be called when either the source or destination type is i64, and my
change also hadn't fixed the most obvious problem -- assuming that i64 will
only be bitconverted to f64, ignoring the various vector types.
Radar 7873160.

Bob Wilson ca51425d94 Re-commit my previous SSAUpdater changes. The previous version naively tried 
to determine where to place PHIs by iteratively comparing reaching definitions
at each block.  That was just plain wrong.  This version now computes the
dominator tree within the subset of the CFG where PHIs may need to be placed,
and then places the PHIs in the iterated dominance frontier of each definition.
The rest of the patch is mostly the same, with a few more performance
improvements added in.

Eric Christopher 8d0c621ca6 Consolidate most of the integer constant expression builtin requirement 
checking into a single function and use that throughout. Remove some

Eric Christopher 7258dcd77f Revert 101465, it broke internal OpenGL testing. 
Probably the best way to know that all getOperand() calls have been handled
is to replace that API instead of updating.
