Chris Lattner 4984e99b83 CR registers are not used by this "target" 
llvm-svn: 23552
 2005-09-30 06:43:58 +00:00
Chris Lattner 6169a78f46 these registers don't belong to any register classes, so don't mark them 
as callee save.  They can never be generated by the compiler.

Chris Lattner b509577605 Refactor this a bit to move ParsingTemplateArgs to only apply to classes, 
not defs.

Implement support for forward definitions of classes.  This implements
TableGen/ForwardRef.td.

llvm-svn: 23548
 2005-09-30 04:53:04 +00:00
Chris Lattner 41815f2aa2 Add a test that you can forward ref a class.

used on a def.

Chris Lattner 33ce5f8a73 Now that self referential classes are supported, get rid of a work-around.

Chris Lattner 5a6199f387 Change this code ot pass register classes into the stack slot spiller/reloader 
code.  PrologEpilogInserter hasn't been updated yet though, so targets cannot
use this info.

 2005-09-29 22:37:24 +00:00
Chris Lattner 366fe04301 Teach tablegen to reassociate operators when possible. This allows it to 
find all of teh pattern matches for EQV from one definition

llvm-svn: 23528
 2005-09-29 21:11:57 +00:00
Chris Lattner a748e3ae5b now that tblgen is smarter, this pattern is not needed. Also, tblgen 
now inverts commuted versions of ANDC/ORC with the current .td file.

llvm-svn: 23527
 2005-09-29 19:29:15 +00:00
Chris Lattner e86824e57a Teach tblgen to build permutations of instructions, so that the target author 
doesn't have to specify them manually.  It currently handles associativity,
e.g. knowing that (X*Y)+Z  also matches  X+(Y*Z)  and will be extended in
the future.

It is smart enough to not introduce duplicate patterns or patterns that can
never match.

Chris Lattner eca4f56646 Make the JIT default to the DAG isel instead of the pattern isel, like LLC. 
The Pattern isel has some strange memory corruption issues going on. :(

This should have been converted over anyway, but it got forgotten somehow
when switching to the dag isel.

Chris Lattner 5b2be1f890 Fix two bugs in my patch earlier today that broke int->fp conversion on X86.

bringing the LLC time down to the CBE time.

Chris Lattner 08c319fbdd Never rely on ReplaceAllUsesWith when selecting, use CodeGenMap instead. 
ReplaceAllUsesWith does not replace scalars SDOperand floating around on
the stack, permitting things to be selected multiple times.
