Vikram S. Adve d76d82b40f Return address register should be marked as "result" for the JMPL instruction 
since it is defined by the instruction.

llvm-svn: 3966
 2002-09-28 17:00:15 +00:00
Vikram S. Adve 6d1036d41b Live ranges for Return value and return address of a Call are no longer 
created here.  Instead they are created in LiveRangeInfo.cpp.  This
simplifies the code here quite a bit.

 2002-09-28 16:59:05 +00:00
Vikram S. Adve cce628aeaf Simplified code that handles call args and rets, so it no longer 
needs the RegClass list to be passed in.

Vikram S. Adve 4bb9866dc5 Simplify Call translation slightly.

Vikram S. Adve 34d16d64b0 Overhaul integer conversions to match C++ ISO standard. 
Don't allow direct FP-to-uint conversion (must be eliminated by preselection).
Address arithmetic for arrays is now entirely 64-bit so no sign-ext needed.

 2002-09-27 14:33:08 +00:00
Vikram S. Adve 40e2347b90 Modify operand order for Create{Sign,Zero}ExtensionInstructions. 
llvm-svn: 3960
 2002-09-27 14:29:45 +00:00
Vikram S. Adve d238de02c7 Bug fix: some redundant copies were not being deleted after detection :-|. 
llvm-svn: 3959
 2002-09-27 14:27:37 +00:00
Vikram S. Adve 46aeb8c7c2 Decompose FP-to-UInt casts into FP-to-ULong-toUInt.

Anand Shukla ca15c99c4d Initial version: it adds 2 empty slots at the top of stack 
llvm-svn: 3872
 2002-09-21 04:58:26 +00:00
Vikram S. Adve bbf45f6960 Added class MachineOptInfo as interface to target-specific 
routines supporting machine code optimization.
Also added method MachineInstrInfo::getNOPOpCode().

Vikram S. Adve e9ac29b475 Moving these files from Code/PreSelection to here. 
Original logs for PreSelection.cpp:

  revision 1.2
  date: 2002/09/17 23:50:32;  author: lattner;  state: Exp;  lines: +1 -3
  Don't put default parameter values into .cpp files, it breaks 3.x compilers

  revision 1.1
  date: 2002/09/16 15:31:13;  author: vadve;  state: Exp;
  New preselection pass that specializes LLVM code for a target machine,
  while remaining in legal portable LLVM form and preserving type
  information and type safety.

llvm-svn: 3838
 2002-09-20 00:29:28 +00:00
Anand Shukla ff0248c47c Removed debug info printing 
llvm-svn: 3778

Vikram S. Adve b048d6633d Use ulong instead of uint for size expressions. 
llvm-svn: 3744
 2002-09-16 15:56:45 +00:00
Vikram S. Adve fff5ffde27 Add methods to query about the representation of LLVM quantities (e.g., 
constants).  Useful for target-dependent LLVM transformations like
Preselection.

llvm-svn: 3743
 2002-09-16 15:56:01 +00:00
Vikram S. Adve 8cbdbd8e2e Don't print out global names unnecesssarily. Also, expose pass 
constructors so passes can be inserted by TargetMachine.cpp.

llvm-svn: 3742
 2002-09-16 15:54:02 +00:00
Vikram S. Adve 36d3e03fa0 Move all the code that creates code generation passes from Sparc.cpp to 
TargetMachine.cpp, since it is entirely machine-independent.
Also, add options to disable optional back-end passes (preselection and
instr. scheduling).

Misha Brukman 834885fb82 Again, including Module makes Function unnecessary.

 2002-09-14 02:07:43 +00:00
Chris Lattner e314bf5264 - Change getelementptr instruction to use long indexes instead of uint 
indexes for sequential types.

llvm-svn: 3683
 2002-09-11 01:21:35 +00:00
Vikram S. Adve d50fb11d18 Silly bug fix: Machine code vector could be empty for a no-op cast instruction, 
e.g., cast double to double.

llvm-svn: 3633

Vikram S. Adve f5d585d185 Add new function UltraSparcInstrInfo::CreateZeroExtensionInstructions.

llvm-svn: 3580

Vikram S. Adve 7bc45123d3 -- Use size of pointer element type instead of pointer type in array offsets! 
-- A few bug fixes in casting between floats and ints.
-- Use SRL reg, 0 instead of AND reg, 0xffffffff to clear high 32 bits.

llvm-svn: 3579
 2002-09-05 18:32:13 +00:00
Vikram S. Adve 93407286ed -- Bug fix: use byte offsets not typed offsets in output assembly! 
-- Add support for ConstantExpr constants (only cast and add operators so far)
-- Avoid generating label Bbss.bss, which sometimes came out twice.

Chris Lattner b0b412e66e - Renamed Type::isIntegral() to Type::isInteger() 
- Added new method Type::isIntegral() that is the same as isInteger, but
    also accepts bool.

Vikram S. Adve 541862fbf3 Sign-extend values used to index arrays (and Simplify 
SetOperandsForMemInstr significantly).  Load and Store
no longer have any indices.  Eliminate spurious sign-extension
on a cast to float/double.

 2002-08-22 02:58:36 +00:00
Vikram S. Adve 2d85a9976a Eliminate bool, boolreg and boolconst nonterminals, and just use 
reg and Constant instead.

llvm-svn: 3441
 2002-08-22 02:56:10 +00:00
Vikram S. Adve e56681c891 Change rules for Not, since it is now implemented as Xor(reg,11..1). 
Eliminate bool, boolreg and boolconst nonterminals, and just use
reg and Constant instead.

llvm-svn: 3440
 2002-08-22 02:55:21 +00:00
Chris Lattner 74469f858f This case JUST handles constantpointer nulls, not all pointers.

 2002-08-20 17:02:48 +00:00
Vikram S. Adve caed269085 Revise code generation for unary Not (boolean and bitwise), which is 
no longer a separate instruction but is instead implemented with XOR.

Chris Lattner 56e9166b84 - Clean up interface to Sparc register handling a bit: 
- Eliminate Sparc*Order classes, moving contents to Sparc*Class classes
   - get register name methods now return const char * const pointers instead
     of std::string's.
   - Added file header comments to SparcRegClassInfo.(cpp|h)
   - Moved BIG constant arrays out of SparcRegClassInfo.h, into
     SparcRegInfo.cpp.  This should allow a LOT of std::string constructors to
     not have to be called.

Chris Lattner 959a5fbf8e * Removed extraneous #includes
