The outer switch only had one valid block so didn't provide any value.

The 3DNow instructions are encoded a little weird, but we can still represent it as an opcode map.

Summary:
As the title says, this makes following code compile:

```
template<typename> struct Foo {};
Foo() -> Foo<void>;

Foo f; // ok
```

Thanks Nicolas Lesser for coining the fix.

There were a few too many places duplicating this.

llvm-svn: 328402

Previously, we used 0 as an alias for VER_NDX_GLOBAL and had a dummy
entry in SharedFile::Verdefs so that the access to the array is within
its boundary. But that's not straightforwad. We can just stop doing both.

offsets for code models other than small/medium. For JIT application,
memory layout is less controlled and can result in truncations
otherwise.

Patch based on one by Olexa Bilaniuk!

llvm-svn: 328400

Fixes layering, since Transforms/Utils doesn't depend on CodeGen, so
shouldn't include headers from it.

llvm-svn: 328399

Should be NFC since nothing used the enum value. The instruction descriptions are generated from tablegen which had the correct value.

llvm-svn: 328398

ValueTypes.h is implemented in IR already.

llvm-svn: 328397

It's also used by utils/TableGen so needs to reside somewhere common to
TableGen and CodeGen.

llvm-svn: 328396

This is used by llvm tblgen as well as by LLVM Targets, so the only
common place is Support for now. (maybe we need another target for these
sorts of things - but for now I'm at least making them correct & we can
make them better if/when people have strong feelings)

llvm-svn: 328395

This includes llvm-c/TargetMachine.h which is logically part of
libTarget (since libTarget implements llvm-c/TargetMachine.h's
functions).

llvm-svn: 328394

This is used from llvm tblgen and the X86Disassembler - the only common
library (apart from TableGen, which probably doesn't make sense to have
as a dependency from a release tool (rather than a use-while-building-llvm
tool) of LLVM)

llvm-svn: 328393

It's implemented in Target & include from other Target headers, so the
header should be in Target.

llvm-svn: 328392

Since SectionBase::getOutputSection handles ICF replaces and
SectionBase::getOffset was handling it in some cases, it is more
consistent to have getOffset always handle it.

llvm-svn: 328391

SectionBase::getOutputSection handles replacement sections, so this
code doesn't have to.

This partially reverts commit r328261. The GCC bug has been fixed in
trunk and has never existed in a released version. Therefore the changes
to variant are unneeded.

However, the additional tests have been left in place.

Summary:
Porting HWASan to Linux x86-64, first of the three patches, compiler-rt part.

The approach is similar to ARM case, trap signal is used to communicate
memory tag check failure. int3 instruction is used to generate a signal,
access parameters are stored in nop [eax + offset] instruction immediately
following the int3 one

Had to add HWASan init on malloc because, due to much less interceptors
defined (most other sanitizers intercept much more and get initalized
via one of those interceptors or don't care about malloc), HWASan was not
initialized yet when libstdc++ was trying to allocate memory for its own
fixed-size heap, which led to CHECK-fail in AllocateFromLocalPool.

Also added the CHECK() failure handler with more detailed message and
stack reporting.

My future commits are going to populate this command and test

Summary:
This was motivated by absence of PrunEH functionality in new PM.
It was decided that a proper way to do PruneEH is to add NoUnwind inference
into PostOrderFunctionAttrs and then perform normal SimplifyCFG on top.

This change generalizes attribute handling implemented for (a removal of)
Convergent attribute, by introducing a generic builder-like class
   AttributeInferer

It registers all the attribute inference requests, storing per-attribute
predicates into a vector, and then goes through an SCC Node, scanning all
the instructions for not breaking attribute assumptions.

The main idea is that as soon all the instructions from all the functions
of SCC Node conform to attribute assumptions then we are free to infer
the attribute as set for all the functions of SCC Node.

It handles two distinct cases of attributes:
   - those that might break due to derefinement of the function code

     for these attributes we are allowed to apply inference only if all the
     functions are "exact definitions". Example - NoUnwind.

   - those that do not care about derefinement

     for these attributes we are allowed to apply inference as soon as we see
     any function definition. Example - removal of Convergent attribute.

Also in this commit:
* Converted all the FunctionAttrs tests to use FileCheck and added new-PM
  invocations to them

* FunctionAttrs/convergent.ll test demonstrates a difference in behavior between
   new and old PM implementations. Marked with FIXME.

* PruneEH tests were converted to new-PM as well, using function-attrs+simplify-cfg
  combo as intended

* some of "other" tests were updated since function-attrs now infers 'nounwind'
  even for old PM pipeline

* -disable-nounwind-inference hidden option added as a possible workaround for a supposedly
  rare case when nounwind being inferred by default presents a problem
