Andrew Lenharth 50d9caf6a4 let us get some do what I meant not what I said stuff checked in. You would think the alpha backend would be 64bit clean

Evan Cheng 14c53b45f5 Added field noResults to Instruction. 
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

Andrew Lenharth f520093eb3 add br pattern, unify JSR and BSR ISel instrs, and add BSR support for DAG 
llvm-svn: 25011

Andrew Lenharth 5b18ed9e60 All addressing modes are now exposed. The only remaining relocated forms 
are for function prologue.

TODO: move external symbols over to using RelLit.
    : have a pattern that matches constpool|globaladdr
    : have a pattern that matches (add x imm) -> x, imm or (...) -> ..., 0

 2005-12-24 08:29:32 +00:00
Andrew Lenharth b9aaea3564 Unify the patterns for loads and stores. Now offset addressing should be 
supported.  This almost completes memory operations.

Andrew Lenharth 4621488965 Let's see if we can break things. 
Lower GOT relative addresses to Lo and HI.
Update both ISels to select them when they can.
Saves instructions here and there.

Andrew Lenharth 873ed82a36 FPSelect and more custom lowering 
llvm-svn: 24535
 2005-11-30 16:10:29 +00:00
Andrew Lenharth 6db615df14 All sorts of stuff. 
Getting in on the custom lowering thing, yay
evilness with fp setcc, yuck
trivial int select, hmmm
in memory args for functions, yay
DIV and REM, always handy.  They should be custom lowered though.

Lots more stuff compiles now (go go single source!).  Of course, none of it
probably works, but that is what the nightly tester can find out :)

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).

1. Pass Value*'s into lowering methods so that the proper pointers can be

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

this should be in a different BB, but in the mean time, I use a branch
