Teach regular and fast isel to set dead flags on unused implicit defs
on calls and similar instructions.

llvm-svn: 106353

Eliminate unnecessary uses of getZExtValue().

llvm-svn: 106279

isValueValidForType can be a static member function.

llvm-svn: 106278

Add const qualifiers to CodeGen's use of LLVM IR constructs.

llvm-svn: 101334

Split ISD::NodeType and a few related items out of SelectionDAGNodes.h
into a separate header to allow clients to use them without pulling in
SelectionDAG-specific declarations.

llvm-svn: 101268

Three changes:
1. Introduce some enums and accessors in the InlineAsm class
that eliminate a ton of magic numbers when handling inline
asm SDNode.
2. Add a new MDNodeSDNode selection dag node t

Three changes:
1. Introduce some enums and accessors in the InlineAsm class
that eliminate a ton of magic numbers when handling inline
asm SDNode.
2. Add a new MDNodeSDNode selection dag node type that holds
a MDNode (shocking!)
3. Add a new argument to ISD::INLINEASM nodes that hold !srcloc
metadata, propagating it to the instruction emitter, which
drops it.

No functionality change.

Make this hack more specific to the Apple gcc 4.2 non-LLVM compiler.

bump FIRST_TARGET_MEMORY_OPCODE back up, there is no reason to make it a tight bound anymore.

Reapply Kevin's change 94440, now that Chris has fixed the limitation on
opcode values fitting in one byte (svn r99494).

Add DAG nodes to represent FP16 <-> FP32 intrinsics

change the LabelSDNode to be EHLabelSDNode and make it hold

with an MCSymbol instead of ID. Fix a bug in MMI.cpp which
would return labels

Make sure HasDebugValue is initialized. This should fix

Add some new bits of debug info handling. No

When forming SSE min and max nodes for UGE and ULE comparisons, it's
necessary to swap the operands to handle NaN and negative zero properly.

Also, reintroduce logic for checking for NaN conditions

When forming SSE min and max nodes for UGE and ULE comparisons, it's
necessary to swap the operands to handle NaN and negative zero properly.

Also, reintroduce logic for checking for NaN conditions when forming
SSE min and max instructions, fixed to take into consideration NaNs and
negative zeros. This allows forming min and max instructions in more
cases.

getSplatIndex assumes that the first element of the mask contains the splat index
which is not always true if the mask contains undefs. Modified it to return
the first non undef value.

Make the non-temporal bit "significant" in MemSDNodes so they aren't
CSE'd or otherwise combined with temporal MemSDNodes.

llvm-svn: 96505

Add non-temporal flags and remove an assumption of default arguments.

give SDValue an operator->, allowing V->isTargetOpcode() and
many other natural things.

don't make insanely large node numbers for no reason,
packing somewhat densely is better than not.

When XDEBUG is enabled, check for SelectionDAG cycles at some key
points. This will help us find future problems like the one
described in PR6019.

llvm-svn: 94019

Add some new debugging APIs to print out "raw" SelectionDAGs to make
understanding CannotYTetSelect and other errors easier.
