5 years agoInitial check-in of Acxxel (StreamExecutor renamed)
Jason Henline [Tue, 25 Oct 2016 20:18:56 +0000 (20:18 +0000)]
Initial check-in of Acxxel (StreamExecutor renamed)

Acxxel is basically a simplified redesign of StreamExecutor.

Here are the major points where Acxxel differs from the current
StreamExecutor design:

* Acxxel doesn't support the kernel and kernel loader types designed for
  emission by the compiler to support type-safe kernel launches. For
  CUDA, kernels in Acxxel can be seamlessly launched using the standard
  CUDA triple-chevron kernel launch syntax that is available with clang
  and nvcc. For CUDA and OpenCL, kernel arguments can be passed in the
  old-fashioned way, as one array of pointers to arguments and another
  array of argument sizes. Although OpenCL doesn't get a type-safe
  kernel launch method, it does still get the benefit of all the memory
  management wrappers. In the future, clang may add support for
  triple-chevron OpenCL kernel launchs, or some other type-safe OpenCL
  kernel launch method.
* Acxxel does not depend on any other code in LLVM, so it builds
  completely independently from LLVM.

The goal will be to check in Acxxel and remove StreamExecutor, or
perhaps to remove the old StreamExecutor and rename Acxxel to
StreamExecutor, so I think Acxxel should be thought of as a new version
of StreamExecutor, not as a separate project.

This patch turns on `-fvisibility-inlines-hidden` when building  the dylib. This is important so that libc++.dylib doesn't accidentally export inline-functions which are ODR used somewhere in the dylib.

On OS X this change has no effect on the current ABI of the dylib. Unfortunately on Linux there are already ~20 inline functions which are unintentionally exported by the dylib. Almost all of these are implicitly generated destructors. I believe removing these function definitions is safe because every "linkage unit" which uses these functions has its own definition, and therefore shouldn't be dependent on libc++.dylib to provide them.

Also could a FreeBSD maintainer comment on the ABI compatibility of this patch?

Add -strip-nonlinetable-debuginfo capability

as input and removes all debug info metadata that is not directly
needed for line tables, thus effectively stripping all type and
variable information from the module.

The primary motivation for this feature was the bitcode work flow
(cf. http://lists.llvm.org/pipermail/llvm-dev/2016-June/100643.html
for more background). This is not wired up yet, but will be in
subsequent patches.  For testing, the new functionality is exposed to
opt with a -strip-nonlinetable-debuginfo option.

The secondary use-case (and one that works right now!) is as a
reduction pass in bugpoint. I added two new bugpoint options
(-disable-strip-debuginfo and -disable-strip-debug-types) to control
the new features. By default it will first attempt to remove all debug
information, then only the type info, and then proceed to hack at any
remaining MDNodes.

In vector-reduction arithmetic, the evaluation off is independent of the order of the input elements of V.

ELF: Simplify handling of *_start/*_end symbols.

We were previously using the (static) addSynthetic function to create
*_start/*_end symbols. This function was doing almost the same thing as
addOptionalSynthetic, except that it would also create the symbol in the
case where it is unreferenced. Because the symbol has hidden visibility,
creating it in that case would have no effect other than adding another
entry to the static symbol table. Remove addSynthetic and change callers to
use addOptionalSynthetic instead.

Add support for __builtin_os_log_format[_buffer_size]

This reverts commit r285007 and reapply r284990, with a fix for the
opencl test that I broke. Original commit message follows:

These new builtins support a mechanism for logging OS events, using a
printf-like format string to specify the layout of data in a buffer.
The _buffer_size version of the builtin can be used to determine the size
of the buffer to allocate to hold the data, and then __builtin_os_log_format
can write data into that buffer. This implements format checking to report
mismatches between the format string and the data arguments. Most of this
code was written by Chris Willmore.
