Duncan Sands d9834b29dd If the value types are equal then this routine 
asserts in later checks rather than producing
the ordinary load it is supposed to.  Avoid all
such hassles by directly returning an ordinary
load in this case.

Rafael Espindola 813a0b1d29 Test byval with a 8 bit aligned struct 
llvm-svn: 43173
 2007-10-19 11:29:21 +00:00
Rafael Espindola 846c19dd70 Add support for byval function whose argument is not 32 bit aligned. 
To do this it is necessary to add a "always inline" argument to the
memcpy node. For completeness I have also added this node to memmove
and memset.  I have also added getMem* functions, because the extra
argument makes it cumbersome to use getNode and because I get confused
by it :-)

Owen Anderson ca831a829d Move Split<...>() into DomTreeBase. This should make the #include's of DominatorInternals.h

Ted Kremenek da9639d1a7 Changed the return type of type-specific Allocate() methods to return 
void*.  This is hint that we are returning uninitialized memory rather
than a constructed object.

entries.

llvm-svn: 43089
 2007-10-17 21:13:50 +00:00
Ted Kremenek a26294201f Added member template functions to MallocAllocator and 
BumpPtrAllocator that implement allocations that return a properly
typed pointer.  For BumpPtrAllocator, the allocated memory is
automatically aligned to the minimum alignment of the type (as
calculated by llvm::AlignOf::Alignment).

llvm-svn: 43087
 2007-10-17 21:10:21 +00:00
Ted Kremenek 391b728a99 Added llvm::AlignOf, a template class whose purpose is to portably

Hartmut Kaiser ec8a8d1f51 Updated VC++ build system. 
Silenced some VC warnings.

I'm getting linker errors, though: unresolved externals:

llvm::Split<class llvm::BasicBlock *,struct llvm::GraphTraits<class llvm::BasicBlock *> >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *)

and

llvm::Split<struct llvm::Inverse<class llvm::BasicBlock *>,struct llvm::GraphTraits<struct llvm::Inverse<class llvm::BasicBlock *> > >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *)

Where are these defined?

Duncan Sands d42c812f4a Return Expand from getOperationAction for all extended 
types.  This is needed for SIGN_EXTEND_INREG at least.
It is not clear if this is correct for other operations.
On the other hand, for the various load/store actions
it seems to correct to return the type action, as is
currently done.
Also, it seems that SelectionDAG::getValueType can be
called for extended value types; introduce a map for
holding these, since we don't really want to extend
the vector to be 2^32 pointers long!
Generalize DAGTypeLegalizer::PromoteResult_TRUNCATE
and DAGTypeLegalizer::PromoteResult_INT_EXTEND to handle
the various funky possibilities that apints introduce,
for example that you can promote to a type that needs
to be expanded.

Duncan Sands ce042d0bc0 Document the fact that the verifier currently requires the 
top bit of a ValueType to be zero.  Enforce this by ensuring
an assertion failure if someone tries to create a ValueType
without this property.  I chose this minimal approach rather
than a more official integration of the notion of reserved
bits into ValueType because I'm hoping that the verifier will
be changed to no longer require this :)

Duncan Sands bbbfbe95f7 Initial infrastructure for arbitrary precision integer 
codegen support.  This should have no effect on codegen
for other types.  Debatable bits: (1) the use (abuse?)
of a set in SDNode::getValueTypeList; (2) the length of
getTypeToTransformTo, which maybe should be refactored
with a non-inline part for extended value types.

Duncan Sands 052c843559 Fixes due to lack of type-safety for ValueType: (1) ValueType

Arnold Schwaighofer b3d58b98d0 Correction to tail call optimization code. The new return address 
was stored to the acutal stack slot before the parameters were

parameters than the caller function. The update should remove the
last failing test case of llc-beta: SPASS.

Chris Lattner 06a4954e6e Change LowerFP_TO_SINT to create the specific code it needs instead of
