Vikram S. Adve 6c697526bf 1. Move most of the constant-fixup code into machine-independent file
InstrSelectionSupport.cpp.  It now happens in a bottom-up pass on
   each BURG tree after the original top-down selection pass on the tree.
2. Handle global values as constants (viz., constant addresses).

2001-10-14 18:10:33 +00:00
Chris Lattner b3368ac9db Move the burg file to here. Add .in suffix to indicate that it gets
preprocessed before burg gets to it

llvm-svn: 794
2001-10-14 17:26:21 +00:00
Chris Lattner 1a176f15dc Make the sparc.burg file be a little more flexible and rubust in the fact of
renumbering of instructions.  It is still horribly broken and grossly dependant on the number of instructions, but now it is a least a little better.

Oh yeah it also works now.

Also, note return value of a Call as an "implicitUse".

Chris Lattner 7fac070215 * Both Method & GlobalVariable now subclass GlobalValue
* ConstPoolPointerReference now represents a pointer to a GlobalValue
* Methods name references are now explicit pointers to methods

llvm-svn: 688
2001-10-01 02:32:34 +00:00
Vikram S. Adve 3652ef7587 Several fixes:
(1) Avoid hard-coding some register numbers.
(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".
