Test out some basic constant-checking.

Add a global CreateGlobalInitOrDestructFunction and use it for creating global init or destruction functions.

llvm-svn: 105649

Rename __tcf_ to __cxx_global_array_dtor. Remove the UniqueAggreDestructorCount from CodeGenFunction and let LLVM handle uniquing the internal functions instead.

build a new declaration for that tag type that will be visible for
future lookups of that tag.

Makefiles: Set Clang CPP compiler flags in a single location, instead of scattered throughout the project Makefiles.

llvm-svn: 105638

 - This eliminates most dependencies on how Clang is installed relative to LLVM.

copy-in of c++ class objects into blocks.

pointer. Original patch by Troy D. Straszheim; fixes PR7283.

llvm-svn: 105621

When checking whether we can place a base subobject at an offset, we don't need to go past the highest offset that's known to contain an empty base subobject.

Fix NEON intrinsic argument passing, support vext.  Most now successfully make it through codegen to the .s file

Since the enum values for each arch's builtins overlap, it is not appropriate to check them when compiling or other archs.  Fixes a problem where compiling for NEON would use x86 sema rules.

ARM.

Fixes PR7310.

llvm-svn: 105590

Extend __builtin_shufflevector to expose the full power of the llvm shufflevector instruction.  This means it can now be used for vector truncation and concatenation.  This will be used for the ARM NEON implementation.

llvm-svn: 105589

 - We actually pretend that we have two separate types for LLVM assembly/bitcode because we need to use the standard suffixes with LTO ('clang -O4 -c t.c' should generate 't.o').

It is now possible to do something like:
  $ clang -emit-llvm -S t.c -o t.ll ... assorted other compile flags ...
  $ clang -c t.ll -o t.o ... assorted other compile flags ...
and expect that the output will be almost* identical to:
  $ clang -c t.c -o t.o ... assorted other compile flags ...
because all the target settings (default CPU, target features, etc.) will all be initialized properly by the driver/frontend.

*: This isn't perfect yet, because in practice we will end up running the optimization passes twice. It's possible to get something equivalent out with a well placed -mllvm -disable-llvm-optzns, but I'm still thinking about the cleanest way to solve this problem more generally.

llvm-svn: 105584

 - This magically enables using 'clang -cc1' as a replacement for most of 'llvm-as', 'llvm-dis', 'llc' and 'opt' functionality.

For example, 'llvm-as' is:
  $ clang -cc1 -emit-llvm-bc FOO.ll -o FOO.bc
and 'llvm-dis' is:
  $ clang -cc1 -emit-llvm    FOO.bc -o -
and 'opt' is, e.g.:
  $ clang -cc1 -emit-llvm -O3 -o FOO.opt.ll FOO.ll
and 'llc' is, e.g.:
  $ clang -cc1 -S -o - FOO.ll

The nice thing about using the backend tools this way is that they are guaranteed to exactly match how the compiler generates code (for example, setting the same backend options).

llvm-svn: 105583

 - These inputs follow an abbreviated execution path, but are still worth handling by FrontendAction so they reuse all the other clang -cc1 features.

Frontend: Move some initialization from CompilerInstance to FrontendAction, to parallel what is done for AST inputs.
