Chris Lattner d685514e2e switch TargetLowering::getConstraintType to take the entire constraint,
not just the first letter.  No functionality change.

Andrew Lenharth c4bdea012b FTOIT and ITOFT are bit converts, and if we drop 21264s, are always available

Reid Spencer e63b6518fa For PR950:
Three changes:
1. Convert signed integer types to signless versions.
2. Implement the @sext and @zext parameter attributes. Previously the
   type of an function parameter was used to determine whether it should
   be sign extended or zero extended before the call. This information is
   now communicated via the function type's parameter attributes.
3. The interface to LowerCallTo had to be changed in order to accommodate
   the parameter attribute information. Although it would have been
   convenient to pass in the FunctionType itself, there isn't always one
   present in the caller. Consequently, a signedness indication for the
   result type and for each parameter was provided for in the interface
   to this method. All implementations were changed to make the adjustment
   necessary.

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 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.
