Gabor Greif 638c823211 remove the private hack from CallInst, it was not supposed to hit the branch anyway
as a positive consequence the CallSite::getCallee() methods now can be rewritten to be
a bit more efficient

Jakob Stoklund Olesen 4583355a78 Remove double-def checking from MachineVerifier, so a register does not have to
be killed before being redefined.

These checks are usually disabled, and usually fail when enabled. We de facto
allow live registers to be redefined without a kill, the corresponding
assertions in RegScavenger were removed long ago.

Dan Gohman 5442c71f2e Thread const correctness through a bunch of AliasAnalysis interfaces and
eliminate several const_casts.

Make CallSite implicitly convertible to ImmutableCallSite.

Rename the getModRefBehavior for intrinsic IDs to
getIntrinsicModRefBehavior to avoid overload ambiguity with CallSite,
which happens to be implicitly convertible to bool.

Nate Begeman b69b182191 Add support for getting & setting the FPSCR application register on ARM when VFP is enabled.
Add support for using the FPSCR in conjunction with the vcvtr instruction, for controlling fp to int rounding.

Bruno Cardoso Lopes 7492a11f0c Support x86 AVX 256-bit instruction intrinsics. Right now support all of them, but
as soon as we properly codegen the simple vector operations in clang, remove the
unnecessary builti-ins/intrinsics from clang and llvm.

are unknown.

2010-08-03 00:56:30 +00:00
Dan Gohman 7cac95778f Make SCEVUnknown a CallbackVH, so that it can be notified directly
of Value deletions and RAUWs, instead of relying on ScalarEvolution's
Scalars map being notified, as that's complicated at best, and
insufficient in general.

This means SCEVUnknown needs a non-trivial destructor, so introduce
a mechanism to allow ScalarEvolution to locate all the SCEVUnknowns.

Rafael Espindola 40f18838b7 The BlockExtractorPass() constructor was not reading the BlockFile and that was
exactly what bugpoint expected it to do.

There was also only one user of
BlockExtractorPass(const std::vector<BasicBlock*> &B), so just remove it and
make BlockExtractorPass read BlockFile.

This fixes bugpoint's block extraction.

Nick, please review.

Bill Wendling 9b8d586039 Add a "Compare" flag to the target instruction descriptor. This will be used
later to identify and possibly remove superfluous compare instructions -- those
that are testing for and setting a status flag that should already be set.

getAdjustedAnalysisPointer. Part of a fix to PR7760.

Duncan Sands cb59bfa7ec Fix the ValueMap copy constructor. The issue is that the map keys are value
handles with a pointer to the containing map.  When a map is copied, these
pointers need to be corrected to point to the new map.  If not, then consider
the case of a map M1 which maps a value V to something.  Create a copy M2 of
M1.  At this point there are two value handles on V, one representing V as a
key in M1, the other representing V as a key in M2.  But both value handles
point to M1 as the containing map.  Now delete V.  The value handles remove
themselves from their containing map (which destroys them), but only the first
value handle is successful: the second one cannot remove itself from M1 as
(once the first one has removed itself) there is nothing there to remove; it
is therefore not destroyed.  This causes an assertion failure "All references
to V were not removed?".

Dan Gohman 3d6ac44d96 Factor out some of the code for updating old SCEVUnknown values, and
extend it to handle the case where multiple RAUWs affect a single
SCEVUnknown.

Add a ScalarEvolution unittest to test for this situation.

Kevin Enderby e5930f142a Added first bit of support for the dwarf .file directive. This patch collects
the info from the .file directive and makes file and directory tables that
will eventually be put out as part of the dwarf info in the output file.

Dan Gohman a7e5a24093 Define a maximum supported alignment value for load, store, and
alloca instructions (constrained by their internal encoding),
and add error checking for it. Fix an instcombine bug which
generated huge alignment values (null is infinitely aligned).
This fixes undefined behavior noticed by John Regehr.

Daniel Dunbar 19a3b37441 Support: Add CrashRecoveryContext helper object.
- Designed as a simple wrapper to allow clients to attempt to catch crashes
   (memory errors, assertion violations, etc.) and do some kind of recovery.

 - Currently doesn't actually attempt to catch crashes.
