2001-11-12 19:42:27 +00:00

working with machine instructions alone.

Vikram S. Adve df6913549a Add edges between call instructions and (a) load/store instructions, and
(b) any instructions that use or set CC registers.  Whether or not the
latter are needed really should be machine-dependent.

Vikram S. Adve 6d19dc9080 1. Add a bottom-up pass on BURG trees that is used to fix constant operands.
Needs to be bottom up because constant values may be forward-substituted
   to their uses (i.e., into the parent in the BURG tree).
2. Move most of the constant-fixup code into machine-indepedent file
   InstrSelectionSupport.cpp.

llvm-svn: 859

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).

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.

   should be done with the instinfo, it just isn't now.

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.
