Chris Lattner f96c8befe0 Minor changes: 
* Reword comment to make more clear
  * Don't print out BB's after modification made
  * Don't delete and new an instruction when we need to move something, just move it.

Chris Lattner 371a878863 New testcase 
llvm-svn: 5018
 2002-12-13 12:10:16 +00:00
Misha Brukman 3374ec7c1b Cleaned up the code: factored out switch/case into a separate function, put 
constants in an array for quick lookup. Stole the idea from elsewhere in
Jello.

llvm-svn: 5017
 2002-12-13 12:00:06 +00:00
Misha Brukman 86ca8840a1 Need to insert all moves due to PHI nodes before *ALL* jumps in a predecessor 
basic block, as there could be multiple.

Brian Gaeke 61edd534b4 lib/Target/X86/InstSelectSimple.cpp: 
The MachineBasicBlock variable name patrol hereby fines Chris Lattner
one bag of nachos, for shadowing global names while his license to do so
was under suspension.

llvm-svn: 5014
 2002-12-13 11:39:18 +00:00
Misha Brukman 35a358d981 This should be more correct: invalidates physical registers that are used in 
an instruction to avoid using them to allocate to other virtual registers.

Brian Gaeke 85b78b7372 Rename all BMI MachineBasicBlock operands to MBB. 
Try to mess around with emitGEPOperation's elementSizeReg to make it work,
again.

llvm-svn: 5009
 2002-12-13 10:50:40 +00:00
Misha Brukman 121ae7d3a7 Treat longs as ints => pretend they're all 32-bit values and squeeze them into 
32-bit registers.

llvm-svn: 5008
 2002-12-13 10:43:09 +00:00
Misha Brukman 89ff3fbcd6 Fixed bug with running out of registers. Also, reinstated namespace which 
disappeared during the last checkin.

llvm-svn: 5003
 2002-12-13 09:59:26 +00:00
Misha Brukman a739167305 This should handle register allocating PHI nodes. 
llvm-svn: 5002
 2002-12-13 09:54:36 +00:00
Misha Brukman 78401cbb3c Added moveReg2Reg() and moveImm2Reg() to accomodate moving data around due to 
PHI nodes.

Brian Gaeke eaeacc5872 lib/Target/X86/InstSelectSimple.cpp: Start counting arguments with 2, 
because arguments start two stack slots off of EBP. Break out of the
 for loop once the argument is found. Increment the counter at the end
 of the loop instead of the beginning. Use addRegOffset and compute
 the scale * index part at compile time instead of using the fancy
 load instruction. Just because an instruction set has wacky addressing
 modes doesn't mean we ought to use them (at least, if you believe Dave
 Patterson).

lib/Target/X86/X86InstrBuilder.h: Add some comments.

test/Regression/Jello/test-loadstore.ll:  Let main return int 0.

llvm-svn: 4999
 2002-12-13 09:28:50 +00:00
Brian Gaeke 44876fdee4 InstSelectSimple.cpp: Give promote32 a comment. Add initial 
implementation of getReg() for arguments.

MachineCodeEmitter.cpp: Fix using EBP with index, scale and no
 displacement (whew!) due to Chris.

Printer.cpp: Fix printing out index and scale in memory references.

Implement ConstantPointerRefs
Treat long/ulongs as if they were integers.  A hack, but an effective one

InstSelectSimple.cpp: Add stub implementation of visitFreeInst.

 Add initial implementation of visitAllocaInst.
