llvm-svn: 1295
 2001-11-13 23:12:53 +00:00
Ruchira Sasanka 36f13d1c2f Fixed a bug concering LR spilling. Earlier, added spilled code was not inserted 
into the instruction stream correctly.

llvm-svn: 1294
 2001-11-13 23:09:30 +00:00
Vikram S. Adve dafc8b909e Do the same for allocating spills to get their alignment right too. 
llvm-svn: 1285
 2001-11-12 23:40:22 +00:00
Vikram S. Adve 6e9422e14c When allocating space on stack for writing a register, 
use the size of the register, not the size of the Value type,
to get the right alignment.

llvm-svn: 1284
 2001-11-12 23:26:35 +00:00
Vikram S. Adve 4b9c46da24 Bug fix in offset alignment computations: don't subtract the padding 
value from size *before* subtracting size from offset!

llvm-svn: 1283
 2001-11-12 23:26:23 +00:00
Ruchira Sasanka c189997516 For phi elimination, now we are generating only one instruction 
using cpValue2Value instead of
passing vector to createCopyInstructionByType.

llvm-svn: 1272
 2001-11-12 19:42:27 +00:00
Vikram S. Adve 03fae5e5db Eliminate most uses of the machine instruction vector for each LLVM instr, 
since some m. instr. may be generated by LLVM instrs. in other blocks.
Handle non-SSA (anti and output) edges and true edges uniformly by
working with machine instructions alone.

 2001-11-11 21:23:33 +00:00
Vikram S. Adve 6cd83556e6 Only add true dep. edges from an earlier to a later instruction. 
This wasn't a problem until we started putting copies for Phi values
that produced cycles in the SchedGraph!

llvm-svn: 1254

llvm-svn: 1207
 2001-11-08 16:43:25 +00:00
Vikram S. Adve 621b90440b Major change to how defs are found when adding dependences (they 
are now found as part of the initial walk of the machine code).
Also memory load/store instructions can be generated for non-memory
LLVM instructions, which wasn't handled before.  It is now.

 2001-11-06 05:11:05 +00:00

llvm-svn: 1009
 2001-10-28 21:45:02 +00:00
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.

llvm-svn: 910
 2001-10-18 22:36:26 +00:00
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
 2001-10-17 23:57:50 +00:00
Vikram S. Adve ad97e4ed84 Separate VM instruction that generates the instructions that compute a value

a temporary used within the instruction sequence for the VM instruction.

llvm-svn: 679
 2001-09-30 23:44:19 +00:00
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.
2. Instruction Scheduling now takes the schedinfo as an argument.  The same
   should be done with the instinfo, it just isn't now.

 2001-09-14 03:46:34 +00:00
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.
