Vikram S. Adve 1679709b71 Two bug fixes that were suppressing some "load-constant-into-register" instrs.

Chris Lattner b3368ac9db Move the burg file to here. Add .in suffix to indicate that it gets 
preprocessed before burg gets to it

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.

Vikram S. Adve 021d523b2f Insert code to load constants used as Call or Return arguments. 
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
* Rename Value::GlobalVal to Value::GlobalVariableVal to avoid confusion

Chris Lattner 0156ba6185 Fix emission of return instructions 
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".

Vikram S. Adve 514180ed83 Make class TargetMachine the common interface to all target-dependent 
information, including instr, sched, and reg information.
This allows us to allocate them all in one place and use them much
more uniformly.

Chris Lattner 8d44b99844 Chris seems fond of #include <vector>. Fix these. Also convert use list in 
Value to a vector instead of a list.

 2001-09-14 05:34:53 +00:00
Chris Lattner f8464e4b8d Checkin changes to: 
1. Clean up the TargetMachine structure.  No more wierd pointers that have to
   be cast around and taken care of by the target.
2. Instruction Scheduling now takes the schedinfo as an argument.  The same
   should be done with the instinfo, it just isn't now.
