 2005-09-24 00:50:51 +00:00
Chris Lattner 0afb14cade Teach the DAG isel generator to emit code that creates nodes. 
Fix a few corner cases parsing things like (i32 imm:$foo)

 2005-09-24 00:40:24 +00:00
Chris Lattner cd093e868e Emit better code (no more copies for var references), and support DAG patterns 
(e.g. things like rotates).

Chris Lattner cc8a564cb1 Emit code that matches the incoming DAG pattern and checks predicates. 
This does not check that types match yet, but PPC only has one integer type
;-).

This also doesn't have the code to build the resultant dag.

llvm-svn: 23370
 2005-09-16 00:29:46 +00:00
Chris Lattner 59e96143a2 teach the type inference code how to infer types for instructions and node 
xforms.  Run type inference on result patterns, so we always have fully typed
results (and to catch errors in .td files).

llvm-svn: 23363
 2005-09-14 23:05:13 +00:00
Chris Lattner 991c7c973a Promote xform fns to be explicit nodes in result patterns, and clean off 
predicates since they will have already matched at this point.

llvm-svn: 23362
 2005-09-14 23:01:59 +00:00
Chris Lattner bc7aabce12 start building the instruction dest pattern correctly. Change the xform 
functions to preserve the Record for the xform instead of making it into a
function name.

Chris Lattner d7d31f3b06 Implement a complete type inference system for dag patterns, based on the 
constraints defined in the DAG node definitions in the .td files.  This
allows us to infer (and check!) the types for all nodes in the current
ppc .td file.  For example, instead of:

Inst pattern EQV:       (set GPRC:i32:$rT, (xor (xor GPRC:i32:$rA, GPRC:i32:$rB), (imm)<<Predicate_immAllOnes>>))

we now fully infer:

Inst pattern EQV:       (set:void GPRC:i32:$rT, (xor:i32 (xor:i32 GPRC:i32:$rA, GPRC:i32:$rB), (imm:i32)<<Predicate_immAllOnes>>))

from:  (set GPRC:$rT, (not (xor GPRC:$rA, GPRC:$rB)))
