10 years ago[PowerPC] Add feature for Power8 vector extensions
Bill Schmidt [Fri, 10 Oct 2014 15:09:43 +0000 (15:09 +0000)]
[PowerPC] Add feature for Power8 vector extensions

The current VSX feature for PowerPC specifies availability of the VSX
instructions added with the 2.06 architecture version.  With 2.07, the
architecture adds new instructions to both the Category:Vector and
Category:VSX instruction sets.  Additionally, unaligned vector storage
operations have improved performance.

This patch adds a feature to provide access to the new instructions
and performance capabilities of Power8.  For compatibility with GCC,
the feature is controlled via a new -mpower8-vector switch, and the
feature causes the __POWER8_VECTOR__ builtin define to be generated by
the preprocessor.

There is a companion patch for llvm being committed at the same time.

Fix IRGen for referencing a static local before emitting its decl

Summary:
Previously CodeGen assumed that static locals were emitted before they
could be accessed, which is true for automatic storage duration locals.
However, it is possible to have CodeGen emit a nested function that uses
a static local before emitting the function that defines the static
local, breaking that assumption.

Fix it by creating the static local upon access and ensuring that the
deferred function body gets emitted. We may not be able to emit the
initializer properly from outside the function body, so don't try.

Fixes PR18020.  See also previous attempts to fix static locals in
PR6769 and PR7101.

little endian targets since Power8 hardware is a minimum requirement,
and Power8 provides reasonable performance for unaligned vector loads
and stores.  Up till now we have not provided "correct" (i.e., big-
endian-compatible) code generation for these interfaces, as to do so
produces poorly performing code.  However, this has become the source
of too many questions.

With this patch, LLVM will now produce compatible code for these
interfaces, but will also produce a deprecation warning message for
PPC64LE when one of them is used.  This should make the porting direction
clearer to programmers.  A similar patch has recently been committed to

David Majnemer [Sun, 5 Oct 2014 05:05:40 +0000 (05:05 +0000)]
MS ABI: Implement thread_local for global variables

Summary:
This add support for the C++11 feature, thread_local global variables.
The ABI Clang implements is an improvement of the MSVC ABI.  Sadly,
further improvements could be made but not without sacrificing ABI
compatibility.

The feature is implemented as follows:
- All thread_local initialization routines are pointed to from the
  .CRT$XDU section.
- All non-weak thread_local variables have their initialization routines
  call from a single function instead of getting their own .CRT$XDU
  section entry.  This is done to open up optimization opportunities to
  the compiler.
- All weak thread_local variables have their own .CRT$XDU section entry.
  This entry is in a COMDAT with the global variable it is initializing;
  this ensures that we will initialize the global exactly once.
- Destructors are registered in the initialization function using
  __tlregdtor.

Emit @llvm.assume for non-parameter lvalue align_value-attribute loads

We already add the align parameter attribute for function parameters that have
the align_value attribute (or those with a typedef type having that attribute),
which is an important special case, but does not handle pointers with value
alignment assumptions that come into scope in any other way. To handle the
general case, emit an @llvm.assume-based alignment assumption whenever we load
the pointer-typed lvalue of an align_value-attributed variable (except for
function parameters, which we already deal with at entry).

I'll also note that this is more general than Intel's described support in:
  https://software.intel.com/en-us/articles/data-alignment-to-assist-vectorization
which states that the compiler inserts __assume_aligned directives in response
to align_value-attributed variables only for function parameters and for the
initializers of local variables. I think that we can make the optimizer deal
with this more-general scheme (which could lead to a lot of calls to
@llvm.assume inside of loop bodies, for example), but if not, I'll rework this
to be less aggressive.

MS ABI: Disallow dllimported/exported variables from having TLS

Windows TLS relies on indexing through a tls_index in order to get at
the DLL's thread local variables.  However, this index is not exported
along with the variable: it is assumed that all accesses to thread local
variables are inside the same module which created the variable in the
first place.

While there are several implementation techniques we could adopt to fix
this (notably, the Itanium ABI gets this for free), it is not worth the
heroics.

Instead, let's just ban this combination.  We could revisit this in the
future if we need to.
