When promoting the result of fp_to_uint/fp_to_sint,
inform the optimizers that the result must be zero/
sign extended from the smaller type.  For example,
if a fp to unsigned i16 is promoted to fp to i32,
then we are allowed to assume that the extra 16 bits
are zero (because the result of fp to i16 is undefined
if the result does not fit in an i16).  This is
quite aggressive, but should help the optimizers
produce better code.  This requires correcting a
test which thought that fp_to_uint is some kind
of truncation, which it is not: in the testcase
(which does fp to i1), either the fp value converts
to 0 or 1 or the result is undefined, which is
quite different to truncation.

Add a new set of helper classes for creating and reading debug
information.  This logically replaces the "Desc" classes in
MachineModuleInfo.  Nice features of these classes are that they:

1. Are much more efficient than MMI because they don't create a
   temporary parallel data structure for debug info that has to be
   'serialized' and 'deserialized' into/out of the module.
2. These provide a much cleaner abstraction for debug info than
   MMI, which will make it easier to change the implementation in
   the future (to be MDNode-based).
3. These are much easier to use than the MMI interfaces, requiring
   a lot less code in the front-ends.
4. These can be used to both create (for frontends) and read (for
   codegen) debug information.  DebugInfoBuilder can only be used
   to create the nodes.

So far, this is implemented just enough to support the debug info
generation needs of clang.  This can and should be extended to
support the full set of debug info constructs, and we should switch
llvm-gcc and llc over to using this in the near future.

This code also has a ton of FIXMEs in it, because the way we
currently represent debug info in LLVM IR is basically insane in a
variety of details.  This sort of issue should be fixed when we
eventually reimplement debug info on top of MDNodes.

Correction for the last patch. Should match the conditional in the first part
of the select match, not the select instruction itself.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58947 91177308-0d34-0410-b5e6-96231b3b80d8

The method of doing the matching with a 'select' instruction was wrong. The
original code was matching like this:

if (match(A, m_Not(m_Value(B))))

B was already matched as a 'select' instruction. However, this isn't matching
what we think it's matching. It would match B as a 'Value', so basically
anything would match to it. In this case, a Constant matched. B was replaced
with a constant representation. And then the wrong value would be used in the
SelectInst::Create statement, causing a crash.

After thinking on this for a moment, and after Nick L. told me how the pattern
matching stuff was supposed to work, the solution was to match NOT an m_Value,
but an m_Select.

If the LHS of the FCMP is coming from a UIToFP instruction, then we don't want
to generate signed ICMP instructions to replace the FCMP. This would violate
the following:

  %2 = fcmp ole double %1, 0.000000e+00

Temporary revert my last commit: it seems it's triggering some subtle bug in backend
and breaks llvm-gcc

CMake: corrected library target name for dependency: LLVMCellSPU ->
LLVMCellSPUCodeGen.

CMake: Reflected changes on the CellSPU target build. May require a
clean start.

Fixed a pasto.

CellSPU: Bring SPU's assembly printer more in-line with current LLVM code
structure. Assembly printer now outputs the correct section for strings.

Try to produce better code when scalarizing VSETCC.

Factor out offset printing code into generic AsmPrinter.
FIXME: it seems, that most of targets don't support
offsets wrt CPI/GlobalAddress', was it intentional?

The Index field of an AttributeWithIndex is of type unsigned, not uint16_t.

StoreInst does not produce any result thus it's useless to create new
variable for it. This greatly reduces amount of unused variables in
llvm2cpp-generated code

Rename startFunctionStub to startGVStub since it's also used for GV non-lazy ptr.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58897 91177308-0d34-0410-b5e6-96231b3b80d8

Tell ARMJITInfo if codegen relocation is PIC. It changes how function stubs are generated.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58896 91177308-0d34-0410-b5e6-96231b3b80d8

Rename isString -> isExternalSymbol; getString -> getExternalSymbol since these work on externsym machine relocations.

CellSPU: Fix prologue/epilogue emission when function contains calls but
theframe size is 0; the prologue and epilogue should be emitted in this case.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58890 91177308-0d34-0410-b5e6-96231b3b80d8

Generated code for generic expansion of SETUGT etc.
is noticeably worse than previous PPC-specific code.
Since the latter was also wrong in some cases and
correctness is more important than efficiency, I'm
disabling this test temporarily while I fix it.

Make FP tests requiring two compares work on PPC (PR 642).
This is Chris' patch from the PR, modified to realize that
SETUGT/SETULT occur legitimately with integers, plus
two fixes in LegalizeDAG to pass a valid result type into
LegalizeSetCC.  The argument of TLI.getSetCCResultType is
ignored on PPC, but I think I'm following usage elsewhere.
