Alkis Evlogimenos 13e8623a3f Cleanup debugging output. 
llvm-svn: 10824
 2004-01-13 21:53:20 +00:00
Alkis Evlogimenos 33f9cb1da7 Fix output of live intervals to show correctly its closed, open 
ranges, i.e. [a,b)

llvm-svn: 10822
 2004-01-13 21:17:47 +00:00
Alkis Evlogimenos 9d0c3d21c8 Remove unneeded check (with the recent change in live variables a use 
of a physical register is always dominated by a def).

Alkis Evlogimenos 6b1ec75da9 Fix bug introduced by previous commit: check if fixed intervals 
overlap before adding their spill weight.

Alkis Evlogimenos ebbd66c042 Correctly compute live variable information for physical registers 
when an implicitely defined register is later used by an alias. For example:

         call foo
         %reg1024 = mov %AL

The call implicitely defines EAX but only AL is used. Before this fix
no information was available on AL. Now EAX and all its aliases except
AL get defined and die at the call instruction whereas AL lives to be
killed by the assignment.

llvm-svn: 10813
 2004-01-13 06:24:30 +00:00
Alkis Evlogimenos 52a714b45b Make LiveVariables::HandlePhysRegUse and 
LiveVariables::HandlePhysRegDef private they use information that is
not in memory when LiveVariables finishes the analysis.

Also update the TwoAddressInstructionPass to not use this interface.

Chris Lattner a4ee66f3ea Finegrainify namespacification. 
This should get hunked over to the Sparc backend, along with
MachineCodeForInstruction and a bunch of files in include/llvm/Codegen,
but those battles will have to wait for a later time.

Alkis Evlogimenos ae5b3d4f74 Add a separate list of fixed intervals. This improves the running time 
of the register allocator as follows:

       before   after
mesa   2.3790  1.5994

Alkis Evlogimenos 08c5311729 Currently we cannot handle two-address instructions of the form: 
A = B op C where A == C, but this cannot really occur in practice
because of SSA form. Add an assert to check that just to be safe.

implementation from the TargetMachine directly.

llvm-svn: 10636
 2003-12-28 21:23:38 +00:00
Alkis Evlogimenos a158dc8104 Reserve ECX and EDI instead of EBX and EDI. Since EBX is a callee 
saved register it has a longer free range than ECX (which is defined
every time there is a fnuction call) which makes ECX a better register
to reserve.

llvm-svn: 10635
 2003-12-28 18:03:52 +00:00
Alkis Evlogimenos 43b587d94d Add coalescing to register allocator. A hint is added to each interval 
which denotes the register we would like to be assigned to (virtual or
physical). In register allocation, if this hint exists and we can map
it to a physical register (it is either a physical register or it is a
virtual register that already got assigned to a physical one) we use
that register if it is available instead of a random one in the free
pool.

llvm-svn: 10604
 2003-12-24 18:53:31 +00:00
Alkis Evlogimenos eeea81483f Do a separate pass to compute spill weights because doing it inline 
with live intervals was missing registers that were used before they
were defined (in the arbitrary order live intervals numbers
instructions).

llvm-svn: 10603
 2003-12-24 15:44:53 +00:00
Alkis Evlogimenos 7d7d7e89d4 Change the way free regusters are computed and perform better

llvm-svn: 10570
 2003-12-21 20:41:26 +00:00
Alkis Evlogimenos 2665d9c6f9 Change weight into a float so that we can take into account the 
nesting level when computing it. Right now the allocator uses:

    w = sum_over_defs_uses( 10 ^ nesting level );

llvm-svn: 10569
 2003-12-21 20:19:10 +00:00

llvm-svn: 10513
 2003-12-18 13:08:52 +00:00
Alkis Evlogimenos 725021cb6c Add TwoAddressInstructionPass to handle instructions that have two or 
more operands and the two first operands are constrained to be the
same. The pass takes an instruction of the form:

        a = b op c

and transforms it into:

        a = b
        a = a op c

and also preserves live variables.

llvm-svn: 10512
 2003-12-18 13:06:04 +00:00
Alkis Evlogimenos 4d87219486 Rename LiveIntervals::expired() to LiveIntervals::expiredAt(). 
llvm-svn: 10511
 2003-12-18 08:56:11 +00:00
Alkis Evlogimenos 15b8036b29 When a variable is killed and redifined in a basic block only one 
killing instruction is tracked. This causes the LiveIntervals to
create bogus intervals. The workaound is to add a range to the
interval from the redefinition to the end of the basic block.

llvm-svn: 10510
 2003-12-18 08:53:43 +00:00
Alkis Evlogimenos 40874c708f Handle multiple virtual register definitions gracefully. 
Move some of the longer LiveIntervals::Interval method out of the

Alkis Evlogimenos aaba4639f8 Change interface of MachineOperand as follows: 
a) remove opIsUse(), opIsDefOnly(), opIsDefAndUse()
    b) add isUse(), isDef()
    c) rename opHiBits32() to isHiBits32(),
              opLoBits32() to isLoBits32(),
              opHiBits64() to isHiBits64(),
              opLoBits64() to isLoBits64().

This results to much more readable code, for example compare
"op.opIsDef() || op.opIsDefAndUse()" to "op.isDef()" a pattern used
very often in the code.

Alkis Evlogimenos 5f1f337d95 Change MRegisterDesc::AliasSet, TargetInstrDescriptor::ImplicitDefs 
and TargetInstrDescriptor::ImplicitUses to always point to a null
terminated array and never be null. So there is no need to check for
pointer validity when iterating over those sets. Code that looked
like:

if (const unsigned* AS = TID.ImplicitDefs) {
  for (int i = 0; AS[i]; ++i) {
    // use AS[i]
  }
}

was changed to:

for (const unsigned* AS = TID.ImplicitDefs; *AS; ++AS) {
  // use *AS
}

llvm-svn: 7153
 2003-07-10 19:43:33 +00:00
Vikram S. Adve 5224b19deb Several fixes to handling of int CC register: 
(1) An int CC live range must be spilled if there are any interferences,
    even if no other "neighbour" in the interf. graph has been allocated
    that reg. yet.  This is actually true of any class with only one reg!

(2) SparcIntCCRegClass::colorIGNode sets the color even if the LR must
    be spilled so that the machine-independent spill code doesn't have to
    make the machine-dependent decision of which CC name to use based on
    operand type: %xcc or %icc.  (These are two halves of the same
register.)

(3) LR->isMarkedForSpill() is no longer the same as LR->hasColor().
    These should never have been the same, and this is necessary now for #2.

(4) All RDCCR and WRCCR instructions are directly generated with the
    phony number for %ccr so that EmitAssembly/EmitBinary doesn't have to
    deal with this.

Misha Brukman 366494ab0d Do not hastily change the Opcode from 'r' to 'i' type if we're not actually 
SETTING the operand to be an immediate or have verified that one of the operands
is really a SignExtended or Unextended immediate value already, which warrants
an 'i' opcode.

 2003-06-05 17:15:04 +00:00
Misha Brukman 4e7bad01ff I have finally seen the light. The code to change the opcode must live higher in 
the loop, and in both cases. In the first case, it is a VReg that is a constant
so it may be actually converted to a constant. In the second case, it is already
a constant, but then if it doesn't change its type (e.g. to become a register
and have the value loaded from memory if it is too large to live in its
instruction field), we must change the opcode BEFORE the 'continue', otherwise
we miss the opportunity.

Vikram S. Adve 24ce4d8eb8 Minor changes. 
llvm-svn: 6470
 2003-05-31 07:41:54 +00:00
Vikram S. Adve ad83684c77 Added MachineCodeForInstruction object as an argument to 
TmpInstruction constructors because every TmpInstruction object has
to be registered with a MachineCodeForInstruction to prevent leaks.
This simplifies the user's code.

llvm-svn: 6468
 2003-05-31 07:39:06 +00:00
Vikram S. Adve 465f9b6738 Changes to allow explicit physical register arguments that have been 
preallocated.  While reg-to-reg dependences were already handled, this
change required new code for adding edges to/from call instructions.
This was part of the extensive changes to the way code generation occurs
for function call arguments and return values.
See log for CodeGen/PhyRegAlloc.cpp.

llvm-svn: 6467
 2003-05-31 07:37:05 +00:00
Vikram S. Adve a83804a29a Extensive changes to the way code generation occurs for function 
call arguments and return values:
Now all copy operations before and after a call are generated during
selection instead of during register allocation.
The values are copied to virtual registers (or to the stack), but
in the former case these operands are marked with the correct physical
registers according to the calling convention.
Although this complicates scheduling and does not work well with
live range analysis, it simplifies the machine-dependent part of
register allocation.

llvm-svn: 6379
 2003-05-27 22:43:19 +00:00
Vikram S. Adve 7366fa1aa6 (1) Added special register class containing (for now) %fsr. 
Fixed spilling of %fcc[0-3] which are part of %fsr.

(2) Moved some machine-independent reg-class code to class TargetRegInfo
    from SparcReg{Class,}Info.

(3) Renamed MachienOperand::opIsDef to MachineOperand::opIsDefOnly()
    and related functions and flags.  Fixed several bugs where only
    "isDef" was being checked, not "isDefAndUse".

Also renamed a few variables, moved them into namespaces, converted outputting

do anyway.

No functional changes have been made. However, this code now compiles.

correctly: skipping instructions by incorrectly incrementing the pointer.

Also adds support for building a reg-to-regclass map, and splits the function
for saving register to stack into two, one suitable for virtual registers
(which also assigns it a physical register) and one for simply storing back
physical registers.

Vikram S. Adve 7228f0c404 Significant changes to correctly spill CC registers and to correctly 
handle conditional move instructions:
-- cpMem<->Reg functions now support CC registers (int and FP) correctly.
-- Scratch registers must be explicitly provided to cpMem<->Reg when
   needed, since CC regs need one to be copied to/from memory.
-- CC regs are saved to a scratch register instead of stack.
-- All regs used by a instruction are now recorded in MachineInstr::regsUsed,
   since regs used to save values *across* an instruction are not obvious
   either from the operands or from the LiveVar sets.
-- An (explicit or implicit) operand may now be both a def and a use.
   This is needed for conditional move operations.
   So an operand may need spill code both before and after the instruction.
-- class MachineCodeForBasicBlock is now an annotation on BasicBlock.

Vikram S. Adve 2780d2dacb Numerous bug fixes: 
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect coloring for CC registers (both int and FP): interferences
   were being completely ignored for int CC and were considered but no
   spills were marked for fp CC!

Also some code improvements:
-- better interface to generating machine instr for common cases
   (many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
   one codegen phase to another (now used to pass information about
   CALL/JMPLCALL operands from selection to register allocation)

Vikram S. Adve 819635eb7c Bug fixes:

    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).

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.
