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
* Rename Value::GlobalVal to Value::GlobalVariableVal to avoid confusion

Chris Lattner e63ddd8df7 Clean up parser, fix a bug that prevented this from working: 
%ListNode3 = global %list { %list* null, int 4 }

because %list is name and the parser expected a literal {..} type there.

In addition, simplified rules that the fix (Allow any Types there, not just a StructType)
made obsolete.  Simplified type propogation a bit.

Chris Lattner 571a6b07b6 * Add support for null as a constant 
* Allow multiple definitions of a type with the same name as long as they are the same type
* Eagerly resolve types to allow #2 to work instead of after the whole const pool has been processed
* Change grammar to require a const before a local constant definition

Chris Lattner ba1c1f2fb6 Pull predecessor and successor iterators out of the CFG*.h files, and plop them into 
the BasicBlock class where they should be.  pred_begin/pred_end become methods on BasicBlock,
and the cfg namespace isn't used anymore.

and the cfg namespace isn't used anymore.

Also pull Interval stuff into the Interval class out of the global namespace

Vikram S. Adve 35622c3fc0 Add different "cast constant value" for several possible types. 
Note these are actually generated by Phis with constant operands.

llvm-svn: 685
 2001-10-01 00:23:12 +00:00
Vikram S. Adve fd72440286 Add vector `implicitUses' to class MachineCodeForVMInstr to hold values 
that are used by the VM instruction but not explicit operands of the
m/c instruction.

llvm-svn: 684
 2001-10-01 00:18:12 +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".

Vikram S. Adve 819635eb7c Bug fixes: 
(1) Ensure that delay slot instructions are not moved out of place (this
    was happening for some CALL instructions).  Basically, we need to
    move all delay slot instructions out of the graph and handle them
    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).

(2) Add edges for LLVM operands that are not machine operands (e.g., Call args)
