The NodeMetadata are maintained in an incremental way. When an edge between

the NodeMetadata need first to have the old edge cost removed, then the new

promotion was occuring right after the removing the old cost, and this was

9 years agoBugfix for missed dependency from store to load in buildSchedGraph().
Jonas Paulsson [Tue, 10 Feb 2015 13:03:32 +0000 (13:03 +0000)]
Bugfix for missed dependency from store to load in buildSchedGraph().

Background: When handling underlying objects for a store, the vector
of previous mem uses, mapped to the same Value, is afterwards cleared
(regardless of ThisMayAlias). This means that during handling of the
next store using the same Value, adjustChainDeps() must be called,
otherwise a dependency might be missed.

For example, three spill/reload (NonAliasing) memory accesses using
the same Value 'a', with different offsets:

    SU(2): store  @a
    SU(1): store  @a, Offset:1
    SU(0): load   @a

In this case we have:

* SU(1) does not need a dep against SU(0). Therefore,SU(0) ends up in
  RejectMemNodes and is removed from the mem-uses list (AliasMemUses
  or NonAliasMemUses), as this list is cleared.

* SU(2) needs a dep against SU(0). Therefore, SU(2) must check
  RejectMemNodes by calling adjustChainDeps().

Previously, for store SUs, adjustChainDeps() was only called if
MayAlias was true, missing the S(2) to S(0) dependency in the case
above. The fix is to always call adjustChainDeps(), regardless of
MayAlias, since this applies both for AliasMemUses and
NonAliasMemUses.

No testcase found for any in-tree target.

[X86][FastIsel] Avoid introducing legacy SSE instructions if the target has AVX.

This patch teaches X86FastISel how to select AVX instructions for scalar
float/double convert operations.

Before this patch, X86FastISel always selected legacy SSE instructions
for FPExt (from float to double) and FPTrunc (from double to float).

For example:
\code
  define double @foo(float %f) {
    %conv = fpext float %f to double
    ret double %conv
  }
\end code

Before (with -mattr=+avx -fast-isel) X86FastIsel selected a CVTSS2SDrr which is
legacy SSE:
  cvtss2sd %xmm0, %xmm0

With this patch, X86FastIsel selects a VCVTSS2SDrr instead:
  vcvtss2sd %xmm0, %xmm0, %xmm0

Added test fast-isel-fptrunc-fpext.ll to check both the register-register and
the register-memory float/double conversion variants.

Zachary Turner [Tue, 10 Feb 2015 05:04:37 +0000 (05:04 +0000)]
Teach llvm_add_library() to find include dirs.

Since header files are not compilation units, CMake does not require
you to specify them in the CMakeLists.txt file.  As a result, unless a
header file is explicitly added, CMake won't know about it, and when
generating IDE-based projects, CMake won't put the header files into
the IDE project.  LLVM currently tries to deal with this in two ways:

  1) It looks for all .h files that are in the project directory, and
     adds those.
  2) llvm_add_library() understands the ADDITIONAL_HEADERS argument,
     which allows one to list an arbitrary list of headers.

This patch takes things one step further.  It adds the ability for
llvm_add_library() to take an ADDITIONAL_HEADER_DIRS argument, which
will specify a list of folders which CMake will glob for header files.
Furthermore, it will glob not only for .h files, but also for .inc
files.

Included in this CL is an update to one of the existing users of
ADDITIONAL_HEADERS to use this new argument instead, to serve as an
illustration of how this cleans up the CMake.

The big advantage of this new approach is that until now, there was no
way for the IDE projects to locate the header files that are in the
include tree.  In other words, if you are in, for example,
lib/DebugInfo/DWARF, the corresponding includes for this project will
be located under include/llvm/DebugInfo/DWARF.  Now, in the
CMakeLists.txt for lib/DebugInfo/DWARF, you can simply write:

  ADDITIONAL_HEADER_DIRS
  ../../include/llvm/DebugInfo/DWARF

as an argument to llvm_add_library(), and all header files will get
added to the IDE project.
