9 years ago[LoopAccesses] Create the analysis pass
Adam Nemet [Wed, 18 Feb 2015 03:43:24 +0000 (03:43 +0000)]
[LoopAccesses] Create the analysis pass

This is a function pass that runs the analysis on demand.  The analysis
can be initiated by querying the loop access info via LAA::getInfo.  It
either returns the cached info or runs the analysis.

Symbolic stride information continues to reside outside of this analysis
pass. We may move it inside later but it's not a priority for me right
now.  The idea is that Loop Distribution won't support run-time stride
checking at least initially.

This means that when querying the analysis, symbolic stride information
can be provided optionally.  Whether stride information is used can
invalidate the cache entry and rerun the analysis.  Note that if the
loop does not have any symbolic stride, the entry should be preserved
across Loop Distribution and LV.

Since currently the only user of the pass is LV, I just check that the
symbolic stride information didn't change when using a cached result.

On the LV side, LoopVectorizationLegality requests the info object
corresponding to the loop from the analysis pass.  A large chunk of the
diff is due to LAI becoming a pointer from a reference.

A test will be added as part of the -analyze patch.

Also tested that with AVX, we generate identical assembly output for the
testsuite (including the external testsuite) before and after.

This is part of the patchset that converts LoopAccessAnalysis into an
actual analysis pass.

so that it no longer required to create an LoopAccessInfo instance in

This was actually causing problems because it would have required
creating LAI much earlier that LV::canVectorizeMemory().

otherwise). Don't do so, however, if we're already seen a use of those bits by

[CMake] Create a custom target for generating extension module.

Previously we would create the extension module as a post-build
step of creating liblldb.  As part of this process, we created
symlinks and did other stuff.

This had several longstanding issues related to target
dependencies, such as not re-creating the symlink if liblldb.dll
failed to link, or if the build was Ctrl+C'ed from.

Then, the script that creates the symlinks began to grow to
include other things, such as argdumper, and it would try to
create symlinks before it had finished building the targets it
needed to symlink to.

This patches addresses all of these problems by creating an
explicit target for the script to run, and making it have a
dependency on all the targets it needs to create symlinks from/to.

* make_symlink_darwin_debug passes 2 arguments into make_symlink, but it required 4 arguments (was fixed by r229159)
* make_symlink doesn't work on OS X

As a quick fix, the r229148 and the r229159 were reverted. Now these errors are fixed.

Summary:
This patch fixes the following tests on OS X:

Revert "Revert "I had recently added a new SBFrame::GetVariables() overload with yet another bool argument""

Reverting this commit led to other failures which I did not see at
first.  This turned out to be an easy problem to fix, so I added
SBVariablesOptions.cpp to the CMakeLists.txt.  In the future please
try to make sure new files are added to CMake.

9 years agoCanonicalize splats as build_vectors (PR22283)

Canonicalize splats as build_vectors (PR22283)

This is a follow-on patch to:
http://reviews.llvm.org/D7093

That patch canonicalized constant splats as build_vectors,
and this patch removes the constant check so we can canonicalize
all splats as build_vectors.

This fixes the 2nd test case in PR22283:
http://llvm.org/bugs/show_bug.cgi?id=22283

The unfortunate code duplication between SelectionDAG and DAGCombiner
is discussed in the earlier patch review. At least this patch is just
removing code...

This improves an existing x86 AVX test and changes codegen in an ARM test.
