10 years agoReplace PROLOG_LABEL with a new CFI_INSTRUCTION.
Rafael Espindola [Fri, 7 Mar 2014 06:08:31 +0000 (06:08 +0000)]
Replace PROLOG_LABEL with a new CFI_INSTRUCTION.

The old system was fairly convoluted:
* A temporary label was created.
* A single PROLOG_LABEL was created with it.
* A few MCCFIInstructions were created with the same label.

The semantics were that the cfi instructions were mapped to the PROLOG_LABEL
via the temporary label. The output position was that of the PROLOG_LABEL.
The temporary label itself was used only for doing the mapping.

The new CFI_INSTRUCTION has a 1:1 mapping to MCCFIInstructions and points to
one by holding an index into the CFI instructions of this function.

I did consider removing MMI.getFrameInstructions completelly and having
CFI_INSTRUCTION own a MCCFIInstruction, but MCCFIInstructions have non
trivial constructors and destructors and are somewhat big, so the this setup
is probably better.

The net result is that we don't create temporary labels that are never used.

10 years ago[X86] Teach the DAGCombiner how to fold a OR of two shufflevector nodes.
Andrea Di Biagio [Thu, 6 Mar 2014 20:19:52 +0000 (20:19 +0000)]
[X86] Teach the DAGCombiner how to fold a OR of two shufflevector nodes.

This patch teaches the DAGCombiner how to fold a binary OR between two
shufflevector into a single shuffle vector when possible.

The rules are:
  1. fold (or (shuf A, V_0, MA), (shuf B, V_0, MB)) -> (shuf A, B, Mask1)
  2. fold (or (shuf A, V_0, MA), (shuf B, V_0, MB)) -> (shuf B, A, Mask2)

The DAGCombiner can take advantage of the fact that OR is commutative and
compute two possible shuffle masks (Mask1 and Mask2) for the resulting
shuffle node.

Before folding a dag according to either rule 1 or 2, DAGCombiner verifies
that the resulting shuffle mask is legal for the target.
DAGCombiner would firstly try to fold according to 1.; If not possible
then it will try to fold according to 2.
If both Mask1 and Mask2 are illegal then we conservatively don't fold
the OR instruction.

[Modules] Fix a layering issue that is actually impacting the modules
selfhost.

The 'Core.h' C-API header is part of the IR LLVM library. (One might
even argue it should be called IR.h, but that's a separate point.) We
can't include it into a Support header without violating the layering,
and in a way that breaks modules. MemoryBuffer's opaque C type was being
defined in the Core.h C-API header despite being in the Support library,
and thus we ended up with this weird issue.

It turns out that there were other constructs from the Support library
in the Core.h header. This patch lifts all of them into Support.h and
then includes that into Core.h.

The only possible fallout is if someone was including Support.h and
relying on Core.h to be visible for their own uses. Considering the
narrow interface actually provided by the C-API for the Support library,
this seems a very, very unlikely mistake.

Fix an inconsistency in treatment of trailing / in path::const_iterator

When using a //net/ path, we were transforming the trailing / into a '.'
when the path was just the root path and we were iterating backwards.
Forwards iteration and other kinds of root path (C:\, /) were already
correct.

[LangRef] Improve llvm.mem.parallel_loop_access example

The following changes have been applied:

  - Removed 'align 4'. We can simplify this away, as it does not provide useful
    information in the example.
  - Use named instructions instead of '%0'. This is nicer, but more importantly
    this makes the IR valid. Before we had two assignments to %0 in a single
    example.
  - Add a missing branch instruction to make the loop structure clear.
  - Move one access into outer.for.body to make it not look that empty.
  - The statments that are only in the outer loop body should not reference the
    inner loop metadata, but only the outer loop. Only statements in both loops
    should reference both surrounding loops.
  - Rename the array indexes to make them all independent. Before there were
    identical array indexes in the inner and the outer loop. We want to
    avoid this special case as it may lead to confusion.
