these as options to the user of scan-build.

Owen Anderson 53d546e40b Have GVN do a pre-pass over the CFG that folds away unconditional branches where possible. This allows local PRE to be more aggressive.

Matthijs Kooijman 121a206292 Remove a few tests which no longer hold for deadargelim (since it is now
allowed to canonicalize return values).

Add a test that checks if return value and function attributes are not removed.

Matthijs Kooijman d881fb0a5b Add a testcase for the canonicalizations now performed by deadargelim.

2008-07-15 14:42:58 +00:00
Matthijs Kooijman c893bf472d Allow deadargelim to change return types even though now values were dead. This
again canonicalizes {i32} into i32 and {} into void.

Matthijs Kooijman 5e8c022e21 Revert r53606. It turns out that explicitely tracking the liveness of the
return value as a whole in deadargelim is really not needed now that we simply
rebuild the old return value and actually prevents some canonicalization from
taking place.

This revert stops deadargelim from changing {i32} into i32 for now, but I'll
fix that next.

2008-07-15 14:39:36 +00:00
Matthijs Kooijman c1da874478 Make deadargelim a bit less smart, so it doesn't choke on nested structs as
return values that are still (partially) live. Instead of updating all uses of
a call instruction after removing some elements, it now just rebuilds the
original struct (With undef gaps where the unused values were) and leaves it to
instcombine to clean this up.

The added testcase still fails currently, but this is due to instcombine which
isn't good enough yet. I will fix that part next.

Matthijs Kooijman 04d4c328ac Don't use isa when we can reuse a previous dyn_cast.
llvm-svn: 53607
2008-07-15 13:39:08 +00:00
Matthijs Kooijman 84194b6768 Make DeadArgElim keep liveness of the return value as a whole in addition to
only the liveness of partial return values (for functions returning a struct).
This is more explicit to prevent unwanted changes in the return value. 

In particular, deadargelim now canonicalizes a function returning {i32} to
returning i32 and {} to void, if the struct returned is not used in its
entirety, but only the single element is used.

Duncan Sands 6162e0377c LegalizeTypes support for promotion of bswap.
In LegalizeDAG the value is zero-extended to
the new type before byte swapping.  It doesn't
matter how the extension is done since the new
bits are shifted off anyway after the swap, so
extend by any old rubbish bits.  This results
in the final assembler for the testcase being
one line shorter.

Matthijs Kooijman 79a8eb547c Let DAE keep a list of live functions, instead of simply marking all arguments
and return values live for those functions. This doesn't change anything yet,
but prepares for the coming commits.

Ted Kremenek 3063b73773 Break off declaration of Analysis enum into Analyses.def. The driver options in
clang.cpp now #include these definitions to create the command line options, and
AnalysisConsumer #includes this file to generate the switch statement to create
actions.

Renamed -check-objc-methodsigs to -warn-objc-methodsigs.

The "missing -dealloc" check is now optional: -warn-objc-missing-dealloc

Nate Begeman 191a6b1f1b http://llvm.org/bugs/show_bug.cgi?id=2523
Add some code to handle vector comparisons, which is the language side
of the llvm vicmp/vfcmp instructions.  Also make the vector-vector and
vector-scalar asign checks a bit more sane under the presence of lax vector
conversions.

Duncan Sands 693185bcee According to the docs, it is possible to have an
extending load of a vector.  Handle this case when
splitting vector loads.  I'm not completely sure
what is supposed to happen, but I think it means
hi should be set to undef.  LegalizeDAG does not
consider this case.
