Brian Gaeke a1640d2427 I think this will handle double args.

 2004-09-30 19:44:32 +00:00
Brian Gaeke 7efd5fcb3a Mark the instructions that have delay slots with the hasDelaySlot flag. 
Add some comments.

 2004-09-30 04:04:48 +00:00
Brian Gaeke 1f48ef2a9a Use TargetMachine::hasDelaySlot() instead of our old switch statement 
to find instrs that have delay slots.

Brian Gaeke fb1fd0cb5f Update list of shootout programs that should be working.

Brian Gaeke ede068a8d3 Tell the target description that calls clobber registers O0...O5.

Brian Gaeke 3a340dd7cd FITOD is spelled "fitod", not "fitos". Ouch. 
llvm-svn: 16591
 2004-09-29 19:59:07 +00:00
Brian Gaeke 47095da661 Don't use .quad to output double constants. The assembler must have a bug or 
something, because the wrong bit patterns get output.

 2004-09-29 19:59:06 +00:00
Brian Gaeke 81f5e08573 Recognize FpMOVD as a move.

Brian Gaeke 4023d4e191 Simplify copyConstantToRegister() for longs, using a pair of recursive calls. 
Copy constant-pool entries' addresses into registers before loading out of them,
to avoid errors from the assembler.
Handle loading call args past the 6th one off the stack.
Add IMPLICIT_DEF pseudo-instrs for double and long arguments passed in register
pairs.
Use FpMOVD to copy doubles around instead of the horrible store-load thing we
were doing before.
Handle 'ret double' and 'ret long'.
Fix a bug in handling 'and/or/xor long'.

llvm-svn: 16577
 2004-09-29 03:34:41 +00:00
Brian Gaeke eae5b17dba Fix bug recognizing moves: isMoveInstr should only treat ORs with %g0 as 
moves, not all ORs.

llvm-svn: 16576
 2004-09-29 03:28:15 +00:00
Brian Gaeke 069bb989e4 Use FpMOVD pseudo-instruction to move doubles around.

llvm-svn: 16574
 2004-09-29 03:27:29 +00:00
Brian Gaeke 7f11dd4825 Fix double and long alignment. 
Call the FPMover pass after register allocation.

llvm-svn: 16573
 2004-09-29 03:26:27 +00:00
Brian Gaeke ead8e39832 Put quotes around argument to .section directive. 
llvm-svn: 16572
 2004-09-29 03:25:40 +00:00
Brian Gaeke 457180c597 Add createSparcV8FPMoverPass(). 
llvm-svn: 16571
 2004-09-29 03:25:39 +00:00
Brian Gaeke ce0ba4857b Pass which converts FpMOVD (double move pseudoinstructions) to pairs 
of FMOVS instrs.

Misha Brukman d409d38151 SparcV8 int regs are not only 32-bits in width, but they are 32-bit aligned! 
llvm-svn: 16526
 2004-09-27 18:22:18 +00:00
Misha Brukman a68d76ebfa Fix the copy-pasto that Brian noticed: V8 int regs are 32-bits wide, not 64. 
llvm-svn: 16518

 2004-09-22 20:08:52 +00:00
Chris Lattner 247c29e4b0 Changes to make this work with Jason's patch. I checked this by hand, but 
would appreciate if others would also look at this to make sure I didn't
botch something obvious

llvm-svn: 16312
 2004-09-13 21:32:03 +00:00
Misha Brukman 04bbe6fa25 Renamed file to SparcV8ISelSimple.cpp 
llvm-svn: 16267
 2004-09-10 18:51:12 +00:00
Brian Gaeke acafb39cc3 This file does not need <iostream>, I think. 
llvm-svn: 16245

llvm-svn: 15791
 2004-08-15 23:07:40 +00:00
Chris Lattner a0b38d3cb1 Code insertion methods now return void instead of an int.

 2004-08-15 22:15:11 +00:00
Chris Lattner 98de1d7795 These methods no longer take a TargetRegisterClass* operand. 
llvm-svn: 15774
 2004-08-15 21:56:44 +00:00
Chris Lattner b08d2a2a11 Update to no longer take MF as an argument

 2004-08-14 22:57:22 +00:00
Misha Brukman 8f951e579b Remove ClassPrefix variable as it's no longer used. 
llvm-svn: 15586
 2004-08-09 19:13:29 +00:00
Misha Brukman 0eb9cee698 The (future) SparcV8 JIT would do well to have a class prefix.

 2004-08-04 17:27:27 +00:00
Chris Lattner 4504b95801 I'm pretty sure that ba is branch always, which is a barrier. Brg should 
check this :)

llvm-svn: 15357
 2004-07-31 02:24:37 +00:00
Chris Lattner 51ebdec5c0 I think that V8 should coallesce registers, don't you? 
llvm-svn: 15192
 2004-07-25 06:19:04 +00:00
Chris Lattner 9ce34cb323 CPR fixes 
llvm-svn: 14960
 2004-07-18 07:26:17 +00:00
Brian Gaeke 135b870f72 Add a class for pseudo-instructions. Use it. 
Add IMPLICIT_USE and IMPLICIT_DEF, a la X86.

llvm-svn: 14884
 2004-07-16 10:32:10 +00:00
Brian Gaeke a57943154e Add what will eventually be the TSFlags. Big switch(opcode) statements are bad. 
llvm-svn: 14883
 2004-07-16 10:31:59 +00:00
Brian Gaeke f486726c56 Add special handling for pseudo-instructions (print them as comments). 
llvm-svn: 14882
 2004-07-16 10:31:47 +00:00
Brian Gaeke 97b71c9fa9 Add to-do list. 
llvm-svn: 14881
 2004-07-16 10:31:36 +00:00
Brian Gaeke 5ce1408537 Do IMPLICIT_DEFs on incoming args' hard regs, to avoid confusing the regalloc. 
Support single-fp incoming args.
Support single-fp outgoing args ('call' operands).
Support double-fp return values.

 2004-07-16 10:31:25 +00:00
Chris Lattner c2726e63ed Delete the allocate*TargetMachine function, which is now dead . 
The shared command line options are now in a header that makes sense.

llvm-svn: 14687
 2004-07-08 09:08:35 +00:00
Brian Gaeke 7b4722e62c Add floating-point branches and compares. Compares don't complete 
until the next cycle, and there's no interlock, so they effectively
have a delay slot.
