Jun Bum Lim [Fri, 3 Nov 2017 20:41:16 +0000 (20:41 +0000)]
Recommit r317351 : Add CallSiteSplitting pass

This recommit r317351 after fixing a buildbot failure.

Original commit message:

    Summary:
    This change add a pass which tries to split a call-site to pass
    more constrained arguments if its argument is predicated in the control flow
    so that we can expose better context to the later passes (e.g, inliner, jump
    threading, or IPA-CP based function cloning, etc.).
    As of now we support two cases :

    1) If a call site is dominated by an OR condition and if any of its arguments
    are predicated on this OR condition, try to split the condition with more
    constrained arguments. For example, in the code below, we try to split the
    call site since we can predicate the argument (ptr) based on the OR condition.

    Split from :
          if (!ptr || c)
            callee(ptr);
    to :
          if (!ptr)
            callee(null ptr)  // set the known constant value
          else if (c)
            callee(nonnull ptr)  // set non-null attribute in the argument

    2) We can also split a call-site based on constant incoming values of a PHI
    For example,
    from :
          BB0:
           %c = icmp eq i32 %i1, %i2
           br i1 %c, label %BB2, label %BB1
          BB1:
           br label %BB2
          BB2:
           %p = phi i32 [ 0, %BB0 ], [ 1, %BB1 ]
           call void @bar(i32 %p)
    to
          BB0:
           %c = icmp eq i32 %i1, %i2
           br i1 %c, label %BB2-split0, label %BB1
          BB1:
           br label %BB2-split1
          BB2-split0:
           call void @bar(i32 0)
           br label %BB2
          BB2-split1:
           call void @bar(i32 1)

[globalisel][tablegen] Skip src child predicates

as SMLABB or similar, but without properly checking for the sext_16_node

[llvm-objcopy] Fix bug in how segment alignment was being handled

Just aligning segment offsets to segment alignment is incorrect and also
wastes more space than is needed. The requirement is that p_offset ==
p_addr modulo p_align *not* that p_offset == 0 modulo p_align. Generally
speaking we've been using p_addr == 0 modulo p_align. In fact yaml2obj
can't even produce a valid situation which causes llvm-objcopy to
produce incorrect results because alignment and offset were both
inherited from the sections the program header covers. This change fixes
this bad behavior in llvm-objcopy.

Summary:
Currently the block frequency analysis is an approximation for irreducible

The new irreducible loop metadata is used to annotate the irreducible loop
headers with their header weights based on the PGO profile (currently this is

Summary:
This patch allows us to predicate range checks that have a type narrower than
the latch check type. We leverage SCEV analysis to identify a truncate for the
latchLimit and latchStart.
There is also safety checks in place which requires the start and limit to be
known at compile time. We require this to make sure that the SCEV truncate expr
for the IV corresponding to the latch does not cause us to lose information
about the IV range.
Added tests show the loop predication over range checks that are of various
types and are narrower than the latch type.
This enhancement has been in our downstream tree for a while.
