8ce9f2956e Renamed MachineCodeEmitter.cpp -> X86CodeEmitter.cpp as it conflicts with the 
target-independent lib/CodeGen/MachineCodeEmitter.cpp; preserved CVS history.

1c70c3f7a3 * Removed SparcEmitter.cpp; rolled into lib/Target/Sparc/SparcV9CodeEmitter.cpp 
* No more createX86Emitter() vs. createSparcEmitter() -- there can be only one
* As a result, the memory management semantics must be handled according to
  platform -- the parameters to mmap() are particularly sensitive to the host
  architecture.

bbbe5d71d2 The flag modifications weren't picking up the old values of the 
flags before. Save them in a temporary variable, then restore them from the
temporary after creating the new constant.

 flags, for the flags that matter.

d43c10b583 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.

b2bb0dd8ca Allow explicit physical registers for implicit operands. 
llvm-svn: 6468
 2003-05-31 07:39:06 +00:00
Vikram S. Adve
2d906f4550 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.

83409b0b78 Several bug fixes: globals in call operands were not being pulled out; 
globals in some other places may not have been pulled out either;
globals in phi operands were being put just before the phi instead of
in the predecessor basic blocks.

194a5862e0 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.
