Dan Gohman 487e250109 Fix LoopSimplify to notify ScalarEvolution when splitting a loop backedge 
into an inner loop, as the new loop iteration may differ substantially.
This fixes PR8078.

Duncan Sands 6778149f7e Reapply commit 112699, speculatively reverted by echristo, since 
I'm sure it is harmless.  Original commit message:
If PrototypeValue is erased in the middle of using the SSAUpdator
then the SSAUpdator may access freed memory.  Instead, simply pass
in the type and name explicitly, which is all that was used anyway.

Dan Gohman ca26f79051 Reapply r112091 and r111922, support for metadata linking, with a 
fix: add a flag to MapValue and friends which indicates whether
any module-level mappings are being made. In the common case of
inlining, no module-level mappings are needed, so MapValue doesn't
need to examine non-function-local metadata, which can be very
expensive in the case of a large module with really deep metadata
(e.g. a large C++ program compiled with -g).

This flag is a little awkward; perhaps eventually it can be moved
into the ClonedCodeInfo class.

Daniel Dunbar ce45863f0d Revert r111922, "MapValue support for MDNodes. This is similar to r109117,

Dan Gohman a209503467 Use MapValue in the Linker instead of having a private function 
which does the same thing. This eliminates redundant code and
handles MDNodes better. MDNode linking still doesn't fully
work yet though.

 2010-08-24 18:50:07 +00:00
Dan Gohman 6901283544 MapValue support for MDNodes. This is similar to r109117, except 
that it avoids a lot of unnecessary cloning by avoiding remapping
MDNode cycles when none of the nodes in the cycle actually need to
be remapped. Also it uses the new temporary MDNode mechanism.

Dan Gohman 4a63fad976 Teach SimplifyCFG how to simplify indirectbr instructions. 
- Eliminate redundant successors.
 - Convert an indirectbr with one successor into a direct branch.

Also, generalize SimplifyCFG to be able to be run on a function entry block.
It knows quite a few simplifications which are applicable to the entry
block, and it only needs a few checks to avoid trouble with the entry block.

Dan Gohman 0141c13b22 Remove LCSSA's bogus dependence on LoopSimplify and LoopSimplify's bogus 
dependence on DominanceFrontier. Instead, add an explicit DominanceFrontier
pass in StandardPasses.h to ensure that it gets scheduled at the right
time.

Declare that loop unrolling preserves ScalarEvolution, and shuffle some
getAnalysisUsages.

This eliminates one LoopSimplify and one LCCSA run in the standard
compile opts sequence.

Nick Lewycky 14b69d59dd Whether function-local or not, a MDNode may reference a Function in which case 
it needs to be mapped to refer to the function in the new module, not the old
one. Fixes PR7700.

Chris Lattner e41ab07c61 make various clients of ReplaceAndSimplifyAllUses tolerate

Owen Anderson 2cfe91379b Extend SimplifyCFG's common-destination folding heuristic to allow a single 
"bonus" instruction to be speculatively executed.  Add a heuristic to
ensure we're not tripping up out-of-order execution by checking that this bonus
instruction only uses values that were already guaranteed to be available.

This allows us to eliminate the short circuit in (x&1)&&(x&2).
