Brian Gaeke 187ff172b6 Support printing constant pool indices. 
If we see an "unknown operand", abort so it's easier to fix it.

 2004-06-27 22:50:44 +00:00
Brian Gaeke c81b5a5331 Trim whitespace. 
Support cast of ints (and narrower) to float and double.
Support cast double to double (using load and store).
Abort if we see a CallInst or SetCondInst with long/fp args, instead
of producing bad code.
Support add, sub, mul, div of float and double.

Chris Lattner d22d9cb800 Do not find these ugly sparc-specific objects by using the annotation API on 
instructions.  Instead, keep a map of instructions -> MCFI objects in the
already sparc-specific class MachineFunctionInfo.  This will slow down the
sparc backend a bit, but it does not penalize the rest of LLVM!

Tanya Lattner 23dbc8170c Made a fix so that you can print out MachineInstrs that belong to a MachineBasicBlock that is not yet attached to a MachineFunction. This change includes changing the third operand (TargetMachine) to a pointer for the MachineInstr::print function.

Misha Brukman 29b3dd7d35 In emitting code for a GEP instr, iterate over GEPTypes because there is one 
more operand in GEPOps than there are types in GEPTypes: the pointer that is the
first operand of the GEP instruction.

llvm-svn: 14375

llvm-svn: 14365
 2004-06-24 09:17:47 +00:00
Brian Gaeke c605ae6754 The long integer pseudo-regs are history. So long, we hardly knew ye. 
llvm-svn: 14364
 2004-06-24 08:55:21 +00:00
Brian Gaeke 4ed2826ce5 Use correct add*Imm form in more BuildMI calls. 
Fix bug in emitGEPOperation where we weren't passing MBB, IP to getReg.

Fix bug in emitGEPOperation where we might try to OR a constant into a
register which was too big to fit in the immediate field.
Support and, or, xor of longs.

llvm-svn: 14363
 2004-06-24 08:55:09 +00:00

llvm-svn: 14362
 2004-06-24 07:37:12 +00:00
Brian Gaeke c8e1b5abe8 Rename the load and store opcodes. The non-fp ones only have one

Brian Gaeke 9f455efff1 Rename the load and store opcodes. The non-fp ones only have one 
variant worth worrying about; the fp ones have two.
Stub out the case analysis of int-to-fp casts (no code yet).
I think the number of operands passed to BuildMI for loads was wrong.
Support load and store of float and double.

llvm-svn: 14359
 2004-06-24 06:52:20 +00:00
Chris Lattner 7a002d6010 Two fixes. First, stop using the ugly shouldSubstituteIndVar method. 
Second, disable substitution of quadratic addrec expressions to avoid putting
multiplies in loops!

llvm-svn: 14358
 2004-06-24 06:49:18 +00:00
Brian Gaeke 8863de761d Strange as it may sound, we'll not use LDD/STD to store longs. For reasons of 
representational consistency, we want to address the halves of each 64-bit value
separately.

llvm-svn: 14356
 2004-06-24 06:44:57 +00:00

 2004-06-24 06:33:00 +00:00
Brian Gaeke ae6fb8ae5c Make the most commonly preselected instructions add to the names of the 
instructions they augment, instead of replacing them.  It's good for debugging,
and it's OK for the sparcv9 backend.

 2004-06-22 17:52:30 +00:00

Chris Lattner f12c4a3d37 *FINALLY* Fix a really nasty nondeterministic bug that has been haunting us 
since May 1st.  In this code, the pred iterator was being invalidated sometimes
causing the wrong entries to be added to PHI nodes.

The fix for this is to defererence and safe the *PI value before we hack on
branch instructions, which changes use/def chains, which SOMETIMES invalidates
the iterator.
