This adds support for the .short and its alias .hword for adding literal values
into the object file.  This is similar to the .word directive, however, rather
than inserting a value of 4 bytes, adds a 2-byte value.

The DiagnosticBuilder's lifetime in parser typo recovery was overlapping with
the subsequent consume which can itself emit PP diagnostics.

Patch by Olivier Goffart!

Now that the integrated assembler is considered a first class feature of the
compiler and has a proper feature flag, document the change in the compiler
flags.  Ensure that we indicate that the legacy flags are still available, but,
encourage users to switch to the feature flags.

llvm-svn: 201964

The integrated assembler is a feature.  This makes the new flags the default
option, and the previous versions aliases.  Ideally, at some point the aliases
would be entirely removed.

In r199283 I switched the name of this variable to CCC_OVERRIDE_OPTIONS, but
I kept some code to continue recognizing the old name temporarily. As far as
I know, the only use of this was for some internal testing at Apple, and we've
now switched to use the new name. If anyone else is still using this and needs
more time to switch names, I guess we'll find out! <rdar://problem/15821425>

Forward the -no-integrated-as option to -cc1 rather than simply invoking the
appropriate tool.  This is useful since this option has been overloaded to
permit disabling of parsing inline assembly at the MC layer.

This re-applies the previous version of the patch with a renaming of the driver
option to the public name rather than the internal name (-target vs -triple).
The actual failure is fixed separately of an overly aggressive negative pattern
match in the MIPS driver tests.  It also fixes the incorrect test for targets
that have the integrated assembler disabled by default.

llvm-svn: 201960

The tests attempt to validate the invocation of the assembler program with the
integrated assembler disabled.  However, the match pattern for the negative
tests are lax and will match both the driver invocation as well as the assembler
invocation.  Make the tests more strict by ensuring that we only match the
assembler invocation.

llvm-svn: 201959

This seems to break a MIPS test.  Revert until I figure out the root cause.

Offsets past the range of single-slash encoding are encoded as base64,
padded to 6 characters, and prefixed with two slashes. This encoding is
undocumented but used by MSVC.

Fix historical #ifdef. Use __cplusplus instead of __GXX_EXPERIMENTAL_CXX0X__ when compiling with clang. No functionality change. Noteto self: It is important to run the regression tests on the copy of the code that you've changed.

This commit moves getSLEB128Size() and getULEB128Size() from
MCAsmInfo to LEB128.h and removes some copy-and-paste code.

Besides, this commit also adds some unit tests for the LEB128
functions.

Polly has been fixed to work with this.

This will make sure polly finds libisl.so at runtime even if the parent
CMakeLists.txt sets CMAKE_INSTALL_RPATH.

This reverts commit r201921.

This should bring the polly bots back. I will try to build it locally to
understand how cmake was setting the rpath of LLVMPolly.so.

The operator+() and operator-() do not change the member

llvm/test/CodeGen/X86/shift-pcmp.ll: Tweak to appease FileCheck. "CHECK-LABEL" doesn't identify labels magically and CHECK-LABEL behaves free from other contexts.

For targeting pecoff, ".def foo" appears before ".short 32".

          .def    foo;
  ...
  .LCPI0_0:
          .short  32
  foo:

CHECK-LABEL seeks not from ".short 32" but from the top of the input.

The language forbids defining enums in prototypes, so this check is normally
redundant, but if an enum is defined during template instantiation it should
not be added to the prototype scope.

While at it, clean up the code that deals with tag definitions in prototype
scope and expand the visibility warning to cover the case where an anonymous
enum is defined.

Per feedback from Aaron Ballman, push cast-to-ObjCProtocolDecl inside handleObjCSuppresProtocolAttr().

This works by asking cmake to use the "install rpath", but setting that rpath
to be relative.

Thanks a lot to Brad King for the help with CMake!

No functional change.  It's unclear if the word FIXME is relevant given

MSVC allows extra-qualification on member functions, it lets you repeat

A recent change caused multi-dimensional arrays not to be handled

This reverts commit r201910.

While __func__ may be standard in C++11, it was only recently added to
MSVC in 2013 CTP, and LLVM supports MSVC 2012.  __FUNCTION__ may not be
standard, but it's *very* portable.
