v2: modify hasVALU32BitEncoding instead
v3: - add pseudoToMCOpcode helper to AMDGPUInstInfo, which is used by both
hasVALU32BitEncoding and AMDGPUMCInstLower::lower
- report an error if a pseudo can't be lowered

We are porting some of the checkers at a company we developed to the Clang Tidy
infrastructure. We would like to open source the checkers that may be useful
for the community as well. This patch is the first checker that is being ported
to Clang Tidy. We also added fix-it hints, and applied them to LLVM:
http://reviews.llvm.org/D6924
The code compiled and the unit tests are passed after the fixits was applied.
The documentation of the checker:
/// The emptiness of a container should be checked using the empty method
/// instead of the size method. It is not guaranteed that size is a
/// constant-time function, and it is generally more efficient and also shows
/// clearer intent to use empty. Furthermore some containers may implement the
/// empty method but not implement the size method. Using empty whenever
/// possible makes it easier to switch to another container in the future.
It also uses some custom ASTMatchers. In case you find them useful I can submit
them as separate patches to clang. I will apply your suggestions to this patch.

Avoid using unions for storing the return value from
LLVMGetGlobalValueAddress() and LLVMGetFunctionAddress() and accessing it as
a pointer through another pointer member. This causes problems on 32-bit big
endian machines since the pointer gets the higher part of the return value of
the aforementioned functions.

The new parser is a lot stricter about syntax, reports unrecognized
flags, and will make it easier to implemented some of the planned features.
llvm-svn: 226169
This patch was generated by a clang tidy checker that is being open sourced.
The documentation of that checker is the following:
/// The emptiness of a container should be checked using the empty method
/// instead of the size method. It is not guaranteed that size is a
/// constant-time function, and it is generally more efficient and also shows
/// clearer intent to use empty. Furthermore some containers may implement the
/// empty method but not implement the size method. Using empty whenever
/// possible makes it easier to switch to another container in the future.

TargetLibraryAnalysis pass.
There are actually no direct tests of this already in the tree. I've
added the most basic test that the pass manager bits themselves work,
and the TLI object produced will be tested by an upcoming patches as
they port passes which rely on TLI.
This is starting to point out the awkwardness of the invalidate API --
it seems poorly fitting on the *result* object. I suspect I will change
it to live on the analysis instead, but that's not for this change, and
I'd rather have a few more passes ported in order to have more
experience with how this plays out.
I believe there is only one more analysis required in order to start
porting instcombine. =]

object from the pass that provides access to it.
We should probably refactor the createTLI code here in Clang in light of
the new structure, but I wanted this patch to be a minimal one that just
patches the behavior back together.
llvm-svn: 226158
The pass is really just a means of accessing a cached instance of the
TargetLibraryInfo object, and this way we can re-use that object for the
new pass manager as its result.
Lots of delta, but nothing interesting happening here. This is the
common pattern that is developing to allow analyses to live in both the
old and new pass manager -- a wrapper pass in the old pass manager
emulates the separation intrinsic to the new pass manager between the
result and pass for analyses.

Types composed with certain implicit record types would have their RTTI
marked as hidden because the implicit record type didn't have any
visibility.
This manifests itself as triggering false positives from tools like
clang's -fsantize=function feature. The RTTI for a function type's
return type wouldn't match if the return type was an implicit record
type.

InputElement was named that because it's an element of an InputGraph.
It's losing the origin because the InputGraph is now being removed.
InputElement's subclass is FileNode, that naming inconsistency needed
to be fixed.
llvm-svn: 226147
They were the last member functions of InputGraph (besides members()).
Now InputGraph is just a container of a vector. We are ready to replace
InputGraph with plain File vector.
