Evan Cheng 3df447d354 For each loop, keep track of all the IV expressions inserted indexed by 
stride. For a set of uses of the IV of a stride which is a multiple
of another stride, do not insert a new IV expression. Rather, reuse the
previous IV and rewrite the uses as uses of IV expression multiplied by
the factor.

e.g.
x = 0 ...; x ++
y = 0 ...; y += 4
then use of y can be rewritten as use of 4*x for x86.

 2006-03-15 19:23:40 +00:00
Chris Lattner 6d6084fd04 Teach the strip pass to strip type names in addition to value names. This 
is fallout from the type/value split in the symtab long long ago :)

Andrew Lenharth 3196422df0 Handle one offset with growth case seen in povray. Namely, if we have an offset, 
and the offset lands at a field boundary in the old type, construct a new type,
copying the fields masked by the offset from the old type, and unify with that.

llvm-svn: 26775

Chris Lattner d00dddeb41 Set TargetPrefix on target-specific intrinsics. That way, in theory, different

Robert Bocchino 81e95ba849 Split the 'vset' instruction into two instructions, 'vsetint' and

integer and fp values.
