Chris Lattner 33900811ee Fix some bugs in the alpha backend, some of which I introduced yesterday, 
and some that were preexisting.  All alpha regtests pass now.

Nate Begeman 371e49515d Implement BR_CC and BRTWOWAY_CC. This allows the removal of a rather nasty 
fixme from the PowerPC backend.  Emit slightly better code for legalizing
select_cc.

Chris Lattner 53676dfd33 Change *EXTLOAD to use an VTSDNode operand instead of being an MVTSDNode. 
This is the last MVTSDNode.

This allows us to eliminate a bunch of special case code for handling
MVTSDNodes.

Also, remove some uses of dyn_cast that should really be cast (which is
cheaper in a release build).

Chris Lattner a7220851c0 Make several cleanups to Andrews varargs change: 
1. Pass Value*'s into lowering methods so that the proper pointers can be
   added to load/stores from the valist
2. Intrinsics that return void should only return a token chain, not a token
   chain/retval pair.
3. Rename LowerVAArgNext -> LowerVAArg, because VANext is long gone.
4. Now that we have Value*'s available in the lowering methods, pass them
   into any load/stores from the valist that are emitted

 2005-06-29 00:39:17 +00:00
Andrew Lenharth 1ef3c0c798 Get rid of all symbolic loads. I now do gernate all relocations sequences 
rather than relying on the assembler.  Only a few more pseudo instructions
left.  Also merge load code paths.

Andrew Lenharth a50adcf57d So, it turns out I forgot that one valid way of restoring GP after a call 
is to use RA, which assumes the called function uses RA for the register
holding the return address when it issues a ret.

Andrew Lenharth 7aba58ab89 Reduce use of pseudo ops 
Namely, output the rellocation flags explicitly when loading constants.
Added benifit: save a load when loading from the constant pool.

Andrew Lenharth 331380b2e2 With setOperationAction(ISD::UINT_TO_FP, MVT::i64, Expand), Legalize 
should be able to handle this case.  The code is there, so let's see
if it works.
