We explicitly specifying all filenames instead of assuming some naming
convention used by clang and opt.

For complex examples it may happen that we do not compute dependences. In this
case we do not want to crash, but just not detect parallel loops.

It does not seem to add a lot of value, as it leaves unclear which parts are
mature and whichs not. Adding this informatin also does not make sense, as it
changes rapidly.

This patch enables vectorization of loops containing backward array
traversal (array stride is -1).

This ensures that the polly passes get properly registered both, when using
polly as a loadable module and when directly linking it into clang/opt/bugpoint.
llvm-svn: 204255
llvm.org/PR19081 reports that the polly dependence analysis causes some h264
compilation to hang. We adjust the compute out, to ensure we do not block on
expensive dependence calculations.
llvm-svn: 204168
This reverts the broken modularized build.
This builds the classic loadable module. The separation
of library and plugin is yet to be done in a future patch.

In case we are at the innermost band, we try to prepare for vectorization. This
means, we look for the innermost parallel loop and strip mine this loop to the
innermost level using a strip-mine factor corresponding to the number of vector
iterations.
For whatever reason, the code that implemented this feature was broken. We now
added a comment, a test case and obviously also the right code.

1) The isl_int -> isl_val changes are the ones Tobias suggested.
One additional isl_val_free is added (and needed)
2) Three scoplib_vector_free are added, maybe we would need even
more (and matrix_free) but it's hard to place them right.
3) Cleaned the includes (and removed 'extern C')
This fixes the broken compilation for the scoplib import and export.

This is necessary to avoid test failures in the CLooG test suite due to the
recent isl update.
We also need to update two polly test cases which rely on a certain order in the
textual description that isl chooses for its sets and maps. Changes here are not
often, but we should probably switch to a check that verifies such maps are
semantically equivalent instead of represented identically.
llvm-svn: 203476
Older isl versions did not properly guard all function declarations for the
use in C++. Specifically, the isl/val_gmp.h header was not properly guarded.
This patch ensures we have the proper guards in place and do not accidentally
link to name-mangled C++ versions of those functions that are not available in
libisl.so.

Value::user_iterator changes in LLVM r203364. Converts several of these
loops to nice range based loops in the process.
Built and tested cleanly for me, yay for being able to fully build and
test Polly changes!
llvm-svn: 203381
We currently need to always name instructions, as the polly test suite currently
matches for certain names. We should improve the test suite at some point.
This fixes 'make check-polly' in NDEBUG builds.
llvm-svn: 202855
For now we only mark innermost loops for the loop vectorizer. We could later
also mark not-innermost loops to enable the introduction of openmp parallelism.
llvm-svn: 202854
PollyIRBuilder is currently just a typedef to IRBuilder<>. Consequently, this
change should not affect behavior. In subsequent patches we will extend its
functionality to emit loop.parallel metadata.
