Vikram S. Adve c228f7a077 Add option to disable scheduling. 
Destroy live-variable information after scheduling so it is
recomputed before later phases (e.g., reg. allocation).

llvm-svn: 1933
 2002-03-21 21:21:13 +00:00
Chris Lattner 06707765fa Make ConvertableToGEP handle cases where the user is indexing into the 
first element of a structure type.  Before this would not be handled because
getStructOffset would either stop immediately (because StopEarly was true
and Offset = 0), or blast past the level we wanted.

Now ConvertableToGEP steps down through the type one level at a time, checking
the Offset and Scale conditions at each step

Chris Lattner 0d984ef719 Fix the: test/Regression/Other/2002-03-20-LevelRaiseCrash.ll bug. It turned 
out that almost always the result of the add was the same as the GEP that
would be generated.  In this case, however, it wasn't, so bad things happened.

Chris Lattner f6c6be2891 1. Fix bug test/Regression/Other/2002-03-20-LevelRaiseBadCodegen.ll 
2. Allow negative scales in ConvertableToGEP, so that this loop from
   alloc_tree in the Olden health benchmark is correctly raised:

       for (i = 3; i >= 0; i--)
         fval[i] = alloc_tree(level - 1, label*4 + i + 1, new);

   Stepping through the array backwards caused a negative scale.

  inconsistent before looking for a type plane (caused a crash)

Chris Lattner 31e9e4d219 * Switch to operation on pointers with PointerTy more consistently 
* Fix misspeling
* Catch SIGFPE for traps
* info XXX now prints the raw contents of the GenericValue
* Switch to calloc instead of malloc (temporarily I hope) to bandaid Olden benchmarks
* Implement binary And & Or
* Convert expressions like this:
     PointerTy SrcPtr = getOperandValue(I->getPtrOperand(), SF).PointerVal;
  to:
    GenericValue SRC = getOperandValue(I->getPtrOperand(), SF);
    PointerTy SrcPtr = SRC.PointerVal;
  because the prior way confuses purify.
* Taint the initial values of the value planes
* Handling 'print bb4' in the interpreter without crashing
* Print nicer stack frames with concise return type
* printf doesn't suck nearly as badly as it used to

(2) Fix some incorrect branch opcodes.
(3) Don't try to move int register to float register!
(4) If an operand being forwarded is a constant and it doesn't fit
    into the immed field of the copy machine instruction, then
    generate a load-constant instead of a copy.
(5) Use (unsigned long) 0 for copying a pointer via "add 0, ptr -> ptr2".

(1) Ensure that delay slot instructions are not moved out of place (this

    along with the delayed control transfer instruction.
(2) Mark scheduled instructions correctly when instructions are scheduled
    in more than one cycle in a single step (due to delay slots).

Chris Lattner 0a823a062c This checkin represents some cleanup of the backend, implementing the following things: 
1. The TargetMachine structure is free to decide the process a particular target uses to generate code.
2. All of the gooee details of the sparc backend are now localized in the lib/CodeGen/TargetMAchine/Sparc directory.  The Sparc.h file that is globally visible is just a stub.
3. The Sparc.h file that esxists now will dissapear entirely someday when we have multiple backends chosen by a factory of some sort.
