-----------------------------------
Robustness testing: AOSP and FFMPEG
-----------------------------------
Polly can now compile all of Android. While most of Android is not the primary
target of polyhedral data locality optimizations, Android provides us with a
large and diverse set of robustness tests. Our new `nightly build bot
<http://lab.llvm.org:8011/builders/aosp-O3-polly-before-vectorizer-unprofitable>`_
ensures we do not regress.
Polly also successfully compiles `FFMPEG <http://fate.ffmpeg.org/>`_ and
obviously the `LLVM test suite
<http://lab.llvm.org:8011/console?category=polly>`_.
---------------------------------------------------------
C++ bindings for isl math library improve maintainability
---------------------------------------------------------
In the context of `Polly Labs <pollylabs.org>`_, a new set of C++ bindings was
developed for the isl math library. Thanks to the new isl C++ interface there
is no need for manual memory management any more and programming with integer
sets became easier in general.
Today::
void isDiffEmptyOrUnionTheUniverse(isl::set S1, isl::set S2) {
isl::set Difference = S1.subtract(S2);
isl::set Union = S1.unite(S2);
if (Difference.is_empty())
return true;
if (Union.is_universe())
return true;
return false;
}
Before::
void isDiffEmptyOrUnionTheUniverse(__isl_take isl_set S1,
__isl_take isl_set S2) {
isl_set *Difference = isl_set_subtract(isl_set_copy(S1),
isl_set_copy(S2));
isl_set *Union = isl_set_union(S1, S2);
isl_bool IsEmpty = isl_set_is_empty(Difference);
isl_set_free(Difference);
if (IsEmpty == isl_bool_error)
llvm_unreachable();
if (IsEmpty)
return true;
isl_bool IsUniverse = isl_set_is_Universe(Union);
isl_set_free(Union);
if (IsUniverse == isl_bool_error)
llvm_unreachable();
if (IsUniverse)
return true;
return false;
}
--------------------------
Improved Polly Diagnostics
--------------------------
Polly now uses the LLVM OptimizationDiagnosticInfo API for emitting diagnostic remarks.
This allows Polly remarks to appear in the yaml optimization record when compiling
with the flag -fsave-optimization-record. This also allow Polly remarks to appear in the opt-viewer
tool, allowing for remarks to be viewed next to the source code, and sorted by hotness.
