[dsymutil] Add (unimplemented) --flat option

dsymutil should by default generate dSYM bundles which are filesystem
hierarchies containing the debug info and an additional Info.plist.
Currently llvm-dsymutil emits raw binaries containing the debug info.
This is what we call the 'flat mode'. Add a -f/-flat option that is
supposed to enable that flat mode, but don't wire it for now, only
pass it to the tests that will need it to stay functional once we
do bundle generation by default.
This basically makes this commit NFC and removes the noise from the
actual commit that adds support for bundle generation.

There is an infinite loop that can occur in Shrink Wrapping while searching

Part of this search checks whether the save/restore points are located in

immediate (post) dominator blocks. However, if the current block does not have
any immediate (post) dominators then this search will result in an infinite
loop. This can occur in code containing an infinite loop.

The modification checks whether the immediate (post) dominator is different from
the current save/restore block. If it is not, then the search terminates and the
current location is not considered as a valid save/restore point for shrink wrapping.

This patch changes the interface to enable the shrink wrapping optimization.

It adds a new constructor, which takes a std::function predicate function that
is run at the beginning of shrink wrapping to determine whether the optimization
should run on the given machine function. The std::function can be overridden by
each target, allowing target-specific decisions to be made on each machine
function.

This is necessary for PowerPC, as the decision to run shrink wrapping is
partially based on the ABI. Futhermore, this operates nicely with the GCC iFunc
capability, which allows option overrides on a per-function basis.

9 years agoValueMapper: Rotate distinct node remapping algorithm
Duncan P. N. Exon Smith [Wed, 5 Aug 2015 23:52:42 +0000 (23:52 +0000)]
ValueMapper: Rotate distinct node remapping algorithm

Rotate the algorithm for remapping distinct nodes in order to simplify
how uniquing cycles get resolved.  This removes some of the recursion,
and, most importantly, exposes all uniquing cycles at the top-level.
Besides being a little more efficient -- temporary MDNodes won't live as
long -- the clearer logic should help protect against bugs like those
fixed in r243961 and r243976.

What are uniquing cycles?  Why do they present challenges when remapping
metadata?

    !0 = !{!1}
    !1 = !{!0}

!0 and !1 form a simple uniquing cycle.  When remapping from one
metadata graph to another, every uniquing cycle gets "duplicated"
through a dance:

    !0-temp = !{!1?}     ; map(!0): clone !0, VM[!0] = !0-temp
    !1-temp = !{!0?}     ; ..map(!1): clone !1, VM[!1] = !1-temp
    !1-temp = !{!0-temp} ; ..map(!1): remap !1's operands
    !2      = !{!0-temp} ; ..map(!1): uniquify: !1-temp => !2
    !0-temp = !{!2}      ; map(!0): remap !0's operands
    !3      = !{!2}      ; map(!0): uniquify: !0-temp => !3

    ; Result
    !2 = !{!3}
    !3 = !{!2}

(In the two "uniquify" steps above, the operands of !X-temp are compared
to the operands of !X.  If they're the same, then !X-temp gets RAUW'ed
to !X; if they're different, then !X-temp is promoted to a new unique
node.  The latter case always hits in for uniquing cycles, so we
duplicate all the nodes involved.)

Why is this a problem?  Uniquable Metadata nodes that have temporary
node as transitive operands keep RAUW support until the temporary nodes
get finalized.  With non-cycles, this happens automatically: when a
uniquable node's count of unresolved operands drops to zero, it
immediately sheds its own RAUW support (possibly triggering the same in
any node that references it).  However, uniquing cycles create a
reference cycle, and uniqued nodes that transitively reference a
uniquing cycle are "stuck" in an unresolved state until someone calls
`MDNode::resolveCycles()` on a node in the unresolved subgraph.

Distinct nodes should help here (and mostly do): since they aren't
uniqued anywhere, they are guaranteed not to be RAUW'ed.  They
effectively form a barrier between uniqued nodes, breaking some uniquing
cycles, and shielding uniqued nodes from uniquing cycles.

Unfortunately, with this barrier in place, the unresolved subgraph(s)
can be disjoint from the top-level node.  The mapping algorithm needs to
find at least one representative from each disjoint subgraph.  But which
nodes are *stuck*, and which will get resolved automatically?  And which
nodes are in the unresolved subgraph?  The old logic was conservative.

This commit rotates the logic for distinct nodes, so that we have access
to unresolved nodes at the top-level call to `llvm::MapMetadata()`.
Each time we return to the top-level, we know that all temporaries have
been RAUW'ed away.  Here, it's safe (and necessary) to call
`resolveCycles()` immediately on unresolved operands.

This should also perform better than the old algorithm.  The recursion
stack is shorter, temporary nodes don't live as long, and there are
fewer tracking references to unresolved nodes.  As the debug info graph
introduces more 'distinct' nodes, remapping should incrementally get
cheaper and cheaper.

Aside from possible performance improvements (and reduced cruft in the
`LLVMContext`), there should be no functionality change here.
