Andrew Lenharth a6bbf33cbf Jimptables working again on alpha. 
As a bonus, use the GOT node instead of the AlphaISD::GOT for internal stuff.

Chris Lattner aa2372562e Patches to make the LLVM sources more -pedantic clean. Patch provided 
by Anton Korobeynikov!  This is a step towards closing PR786.

Nate Begeman 595ec734fc Implement Promote for VAARG, and allow it to be custom promoted for people 
who don't want the default behavior (Alpha).

Nate Begeman e74795cd70 First part of bug 680: 
Remove TLI.LowerVA* and replace it with SDNodes that are lowered the same
way as everything else.

Andrew Lenharth ba97ea52d4 yea, lowering this stuff will basically work

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

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 :)

Andrew Lenharth 5a990417f8 Well, the Constant matching pattern works. Can't say much about calls or globals yet.

Andrew Lenharth 7b69867052 ret 0; works, not much else 
still lots of uglyness.
Maybe calls will come soon.
Fixing the return value of things will be necessary to make alpha work.
