"In order to ease automatic bindings generation, it would be helpful if boolean values were distinguishable from integers. The attached patch introduces "typedef int LLVMBool;", and uses LLVMBool instead of int throughout the C API, wherever a boolean value is called for."

Disable  copy ctor and operator= for NamedMDSymTable. Hide typedef that should be public.

Compare the dominance information calculated using a dominance tree walk to the
information calculated based on DFS numbers, if XDEBUG is enabled.

llvm-svn: 92969

Remove a FIXME and unify code that was necessary to work around broken
updateDFSNumbers().  Before updateDFSNumbers() did not work correctly for post
dominators.

llvm-svn: 92968

The DFS number calculation for postdominators was broken. In the case of
multiple exits that form the post dominator root nodes, do not iterate over
all exits, but start from the virtual root node. Otherwise bbs, that are not
post dominated by any exit but by the virtual root node, will never be assigned
a DFS number.

Revert r92939.  These intrinsics get matched to LLVM instructions,
so removing at Chris' request.

llvm-svn: 92947

Add some "missing" instrinsics to make the SSE intrinsic set a bit more
orthogonal.

Some instructions refer to unique labels, and so cannot be trivially cloned
with CloneMachineInstr.

(OP (trunc x), (trunc y)) -> (trunc (OP x, y))

Unfortunately this simple change causes dag combine to infinite looping. The problem is the shrink demanded ops optimization tend to canonicalize expressions in the opposite manner. That is badness. This patch disable those optimizations in dag combine but instead it is done as a late pass in sdisel.

This also exposes some deficiencies in dag combine and x86 setcc / brcond lowering. Teach them to look pass ISD::TRUNCATE in various places.

memcpy, memset and other intrinsics that only access their arguments
to be readnone if the intrinsic's arguments all point to local memory.
This improves the testcase in the README to readonly, but it could in
theory be made readnone, however this would involve more sophisticated
analysis that looks through the memcpy.

llvm-svn: 92829

An instruction like this:

  %reg1097:1<def> = VMOVSR %R3<kill>, 14, %reg0

Must be replaced with this when substituting physical registers:

  %S0<def> = VMOVSR %R3<kill>, 14, %reg0, %D0<imp-def>

uses several kinds of opcode values which are not declared within
that enum. This fixes PR5946.

a single pointer (PointerIntPair) member. In "small" mode, the
pointer field is reinterpreted as a set of bits. In "large" mode,
the pointer points to a heap-allocated object.

Also, give BitVector empty and swap functions.

And, add some simple unittests for BitVector and SmallBitVector.

Fix a build error by adding a missing commit.

This is also a micro-optimization, as passing a SDNode * around is
simpler than passing a { SDNode *, int } by value or reference.
