Presently, the version number of the VSIX matches the LLVM version number. However, as this number doesn't change often, it means that as we release new versions of this VSIX, it will have the same version number, which means users must first uninstall the old version before installing the new one. With this change, we generate a 4th part to the version number that is a date stamp (year, month, day); for example: 4.0.0.161203.

When a macro expending to a literal is used in a comparison, use the macro name
in the diagnostic rather than the literal. This improves readability of path
notes.
Added tests for various macro literals that could occur. Only BOOl, Int, and
NULL tests have changed behavior with this patch.

Summary:
When reading an ASTRecord, each RecordData is logically contained within a
single ModuleFile, and global(er) state is contained by a single ASTReader. This
means that any operations that read from a RecordData and reference an ASTReader
or a ModuleFile, will always reference the same ASTReader or ModuleFile.
ASTRecordReader groups these together so that parameters don't need to be
duplicated ad infinitum. Most uses of the Idx variable seem to be redunant
aliases as well, but I'll leave that for now.

Extend the fix from rL286952 to unittests. The fix added clang built
library directories (via llvm_shlib_dir) to LD_LIBRARY_PATH.
The previous logic has used llvm_libs_dir only which points to installed
LLVM when doing stand-alone builds.
The patch also removes the redundant win32 code that is no longer
necessary now that shlibdir is used unconditionally.

This lets you build with one CUDA installation but use ptxas from

This is useful e.g. if you want to avoid bugs in an old ptxas without
actually upgrading wholesale to a newer CUDA version.

The UBSAN runtime is built static on Windows. This requires that we give local
storage always. This impacts Windows where the linker would otherwise have to
generate a thunk to access the symbol via the IAT. This should repair the
windows clang build bots.
llvm-svn: 289829
Summary:
This implements execute-only support for ARM code generation, which
prevents the compiler from generating data accesses to code sections.
The following changes are involved:
* Add the CodeGen option "-arm-execute-only" to the ARM code generator.
* Add the clang flag "-mexecute-only" as well as the GCC-compatible
alias "-mpure-code" to enable this option.
* When enabled, literal pools are replaced with MOVW/MOVT instructions,
with VMOV used in addition for floating-point literals. As the MOVT
instruction is required, execute-only support is only available in
Thumb mode for targets supporting ARMv8-M baseline or Thumb2.
* Jump tables are placed in data sections when in execute-only mode.
* The execute-only text section is assigned section ID 0, and is
marked as unreadable with the SHF_ARM_PURECODE flag with symbol 'y'.
This also overrides selection of ELF sections for globals.

Unfortunately _setjmp3 can be both import or local. The ASAN tests try to
emulate the flags which makes this harder to detect. Rely on the linker
creating or using thunks here instead. Should repair the ASAN windows bots.

Properly attribute DLL storage to runtime functions. When generating the
runtime function, scan for an existing declaration which may provide an explicit
declaration (local storage) or a DLL import or export storage from the user.
Honour that if available. Otherwise, if building with a local visibility of the
public or standard namespaces (-flto-visibility-public-std), give the symbols
local storage (it indicates a /MT[d] link, so static runtime). Otherwise,
assume that the link is dynamic, and give the runtime function dllimport
storage.
This allows for implementations to get the correct storage as long as they are
properly declared, the user to override the import storage, and in case no
explicit storage is given, use of the import storage.

Most of the PowerPC64 code generation already creates PIC access. This
changes to a full PIC default, similar to what GCC is doing.
Overall, a monolithic clang binary shrinks by 600KB (about 1%). This can
be a slight regression for TLS access and will use the TOC more
aggressively instead of synthesizing immediates. It is expected to be
performance neutral.

Summary:
D27549 (partial fix for PR26619) emits a constant value in the debug
metadata for a floating-point static const that does not exceed 64
bits in size. Whether or not a long double exceeds 64 bits in size
depends on the target. Modify the test case so that it expects a
constant value for long double if and only if the long double is no
larger than 64 bits.

r289225 broke AST invariants by reparenting enumerators into function
decl contexts. This improves things by only reparenting TagDecls while
also attempting to preserve the lexical declcontext chain. The
interesting example here is:
int f(struct S { enum E { a = 1 } b; } c);
The semantic contexts of E and S should be f, and the lexical context of
S should be f and the lexical context of E should be S. We didn't do
that with r289225, but now we should.
This change should also improve our behavior on this example:
void f() {
extern void ext(struct S { } o);
// S injected here
}
Before r289225 we would only remove 'S' from the surrounding tag
injection context if it was the TU, but now we properly reparent S from
f to ext.

At least the plugin used by the LibreOffice build
(<https://wiki.documentfoundation.org/Development/Clang_plugins>) indirectly
uses those members (through inline functions in LLVM/Clang include files in turn
using them), but they are not exported by utils/extract_symbols.py on Windows,
and accessing data across DLL/EXE boundaries on Windows is generally
problematic.
