The problem is that the struct file_status on UNIX systems has two
members called st_dev and st_ino; those are also members of the
struct stat, and they are reserved identifiers which can also be
provided as #define (and this is the case for st_dev on Hurd).
The solution (attached) is to rename them, for example adding a
"fs_" prefix (= file status) to them.

Fix issue 67 by checking that the interface functions weren't redefined in the compiled source file.

llvm-svn: 155346

llvm-svn: 155341

Use MVT instead of EVT through all of LowerVECTOR_SHUFFLEtoBlend and not just the switch. Saves a little bit of binary size.

llvm-svn: 155339

Make getZeroVector and getOnesVector more alike as far as how they detect 128-bit versus 256-bit vectors. Be explicit about both sizes and use llvm_unreachable. Similar changes to getLegalSplat.

llvm-svn: 155337

llvm-svn: 155336

Tidy up spacing in LowerVECTOR_SHUFFLEtoBlend. Remove code that checks if shuffle operand has a different type than the the shuffle result since it can never happen.

fixes an assert reading "1239123123123123" when the result is already 64-bit.

intructions are processed. So there's no need to look at them if they're used as
operands of other instructions.

llvm-svn: 155327

Make Extract128BitVector and Insert128BitVector take an unsigned instead of an ConstantNode SDValue. getConstant was almost always called just before only to have the functions take it apart and build a new ConstantSDNode.

llvm-svn: 155325

llvm-svn: 155321

Make calls to getVectorShuffle more consistent. Use shuffle VT for calls to getUNDEF instead of requerying. Use &Mask[0] instead of Mask.data().

llvm-svn: 155320

llvm-svn: 155319

Simplify code by converting multiple places that were manually concatenating 128-bit vectors to use either CONCAT_VECTORS or a helper function. CONCAT_VECTORS will itself be lowered to the same pattern as before. The helper function is needed for concats of BUILD_VECTORs since getNode(CONCAT_VECTORS) will just return a large BUILD_VECTOR and we may be trying to lower large BUILD_VECTORS when this occurs.

The X86 target is editing the selection DAG while isel is selecting
nodes following a topological ordering. When the DAG hacking triggers
CSE, nodes can be deleted and bad things happen.

Now that multiple DAGUpdateListeners can be active at the same time,
ISelPosition can become a local variable in DoInstructionSelection.

We simply register an ISelUpdater with CurDAG while ISelPosition exists.

llvm-svn: 155249

Instead of passing listener pointers to RAUW, let SelectionDAG itself
keep a linked list of interested listeners.

This makes it possible to have multiple listeners active at once, like
RAUWUpdateListener was already doing. It also makes it possible to
register listeners up the call stack without controlling all RAUW calls
below.

DAGUpdateListener uses an RAII pattern to add itself to the SelectionDAG
list of active listeners.

The <undef> flag on a def operand only applies to partial register
redefinitions. Only print the flag when relevant, and print it as
<def,read-undef> to make it clearer what it means.
