David Goodwin 00822aabf6 Chain dependencies used to enforce memory order should have latency of 0 (except for true dependency of Store followed by aliased Load... we estimate that case with a single cycle of latency assuming the hardware will bypass)

Evan Cheng 2729543984 Initilize the machine LICM CSE map upon the first time an instruction is hoisted to
the loop preheader. Add instructions which are already in the preheader block that
may be common expressions of those that are hoisted out. These does get a few more
instructions CSE'ed.

Chris Lattner 879e05ab1f now that ip sccp *really* subsumes ipcp, remove ipcp again.

Chris Lattner 9d49f0c858 improve IPSCCP to be able to propagate the result of "!mayBeOverridden"
function to calls of that function, regardless of whether it has local
linkage or has its address taken.  Not escaping should only affect 
whether we make an aggressive assumption about the arguments to a 
function, not whether we can track the result of it.

a shared place instead of duplicating it 4 times.

Chris Lattner 4910b656b2 remove some confused code that dates from when we had
"multiple return values" but not "first class aggregates"

Chris Lattner e77c9aa04a Use the libanalysis 'ConstantFoldLoadFromConstPtr' function
instead of reinventing SCCP-specific logic.  This gives us
new powers.

2009-11-02 06:06:14 +00:00
Chris Lattner f548403989 switch the main 'ValueState' map from being an std::map to being
a DenseMap.  Doing this required being aware of subtle iterator
invalidation issues, but it provides a big speedup.  In a 
release-asserts build, this sped up optimizing 403.gcc from
1.34s -> 0.79s (IPSCCP) and 1.11s -> 0.44s (SCCP).

This commit also conflates in a bunch of general cleanups, sorry.

of the two loads agree.  Propagate that onto the new store.

Anton Korobeynikov 0f38d989bd Do not infer the target type for COPY_TO_REGCLASS from dest regclass, this won't work if it can contain several types. Require explicit result type for the node for now. This fixes PR5364.
PS: It seems that blackfin usage of copy_to_regclass is completely bogus!

Anton Korobeynikov 14635da94b Use NEON reg-reg moves, where profitable. This reduces "domain-cross" stalls, when we used to mix vfp and neon code (the former were used for reg-reg moves)

Chris Lattner ef94654363 fix two strange things in the default passmgr:
1. we'd run simplifycfg at the very start, even though
the per function passes have already cleaned this up.

2. In the main per-function pipeline that is interlaced with inlining 
   etc, we would do instcombine, jump threading, simplifycfg *before*
   doing SROA.  SROA is much more likely to expose opportunities for
   these passes than they are for SROA, so move SRoA up earlier.

also add some comments.

Douglas Gregor 0840cc02ce When determining whether a reference to a static data member is an
integral constant expression, make sure to find where the initializer
was provided---inside or outside the class definition---since that can
affect whether we have an integral constant expression (and, we need
to see the initializer itself).

Chris Lattner 3e6398baa5 merge phi-merge.ll into phi.ll
I don't know what Dan wants to do with phi-merge-gep.ll, I'll let
him deal with it because instcombine may end up sinking these.

Chris Lattner 328ef89bd1 when merging two loads, make sure to take the min of their alignment,
not the max.  This didn't matter until the previous patch because
instcombine would refuse to sink loads with differenting alignments.
