major surgery on tblgen: generalize TreePatternNode
to maintain a list of types (one for each result of
the node) instead of a single type.  There are liberal
hacks added to emulate the old behavior in various
situations, but they can start disolving now.

two inputs (which have to be the same type) and *returning an i32*.
This is how the SDNodes get made in the graph, but we weren't able
to model it this way due to deficiencies in the pattern language.

 def UCOM_FpIr80: FpI_<(outs), (ins RFP80:$lhs, RFP80:$rhs), CompareFP,
-                  [(X86cmp RFP80:$lhs, RFP80:$rhs),

+                  [(set EFLAGS, (X86cmp RFP80:$lhs, RFP80:$rhs))]>;

-def : Pat<(parallel (X86cmp GR8:$src1, 0), (implicit EFLAGS)),
+def : Pat<(X86cmp GR8:$src1, 0),
           (TEST8rr GR8:$src1, GR8:$src1)>;

This relies on matching the result of TEST8rr (which is EFLAGS, which is
an implicit def) to the result of X86cmp, an i32.

Bob Wilson [Thu, 18 Mar 2010 18:42:41 +0000 (18:42 +0000)]
Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() to
always create a new jump table.  The intention was to avoid merging jump
tables in SelectionDAGBuilder, and to wait for the branch folding pass to
merge tables.  Unfortunately, the same getJumpTableIndex() method is also
used to merge tables in branch folding, so as a result of this change
branch tables are never merged.  Worse, the branch folding code is expecting
getJumpTableIndex to always return the index of an existing table, but with
this change, it never does so.  In at least some cases, e.g., pr6543, this
creates references to non-existent tables.

I've fixed the problem by adding a new createJumpTableIndex function, which
will always create a new table, and I've changed getJumpTableIndex to only
look at existing tables.
