Bill Wendling c7b2ab9bdf Instead of yet another enum indicating the "assembly language flavor", 
just use the one that's in the subtarget.

Chris Lattner 5488ade154 Fix PR918 by only using typedefs to name struct types. This makes the later 
type ordering stuff work better.  This fixes PR918 and
CodeGen/CBackend/2007-01-15-NamedArrayType.ll

Chris Lattner 4dc4489286 Fix PR1114 and CodeGen/Generic/2007-01-15-LoadSelectCycle.ll by being 
careful when folding "c ? load p : load q" that C doesn't reach either load.
If so, folding this into load (c ? p : q) will induce a cycle in the graph.

Bill Wendling e21237e59a Fix for PR1095: 
LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for
the X86 and PPC backends. It defaults to "0", the first variant of a compound
inline asm expression.

Chris Lattner 479a9fc492 Fix a regression in my isIntegral patch that broke 471.omnetpp. This is 
because TargetData::getTypeSize() returns the same for i1 and i8.  This fix
is not right for the full generality of bitwise types, but it fixes the
regression.

Nick Lewycky 6ce36cff3a Don't print address of ETNode. Print the DFSNumIn which uniquely identifies 
the basic block and is stable across runs in gdb or valgrind.

Make Node::update handle edges which dominate and are tighter than
existing edges.

Replace makeEqual's "squeeze theorem" code. Fixes miscompilation.

Gate the calls to defToOps and opsToDef. Before this, we were getting IG
edges about values which weren't even defined in the dominated area. This
reduces the size of the IG by about half.

Chris Lattner 03c4953cdd rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger. 
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)

 2007-01-12 07:25:16 +00:00
Reid Spencer 7a9c62baa6 For PR1064: 
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.
