Chris Lattner 6b668f228f Further revisions of the FDHandle idea. In this version we use ownership 
semantics that are the same as those used by std::auto_ptr.  This allows
copying of FDHandle's, but copying transfers ownership.

John Criswell 1b921c486e Allow C++ programs to end in .cc. This allows C++ test programs in the 
test suite to compile.

Chris Lattner 0120e92b2b Add trivial exception specs to produce better code since the methods cannot 
be inlined.

Chris Lattner 5d236005b0 Clean up a lot of the code I added yesterday by exposing the IntrinsicLowering 
implementation from the TargetMachine directly.

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.

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: 10634
 2003-12-28 17:58:18 +00:00
Alkis Evlogimenos 52564b2071 Add TargetInstrInfo::isMoveInstr() to support coalescing in register 
allocation.

Reimplement the Interpreters implementation of va_* to be more direct.

Chris Lattner b697370e97 Add new interface that allows removal of some code from the code generators, 
provides for future extensibility, might help the LLVA project avoid having to
hack their own LLI, and provides support required for the experimental Venus
project.

Chris Lattner 079f4d5e71 * eliminate the -f argument to lli, as it was silly and never useful anyway 
* Inline callMain function
* Remove hack from the ExecutionEngines where the 'run' method would automatically
  run atExit functions.  Fixing this requires explicitly calling exit if main returns

Alkis Evlogimenos 2e8c984c58 Improve debugging output when choosing a register to spill. 
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).

Chris Lattner 547508d542 Hrm is a really nasty ommission. The lack of this destructor was causing abstract 
types to never be deleted, manifesting itself as many OpaqueType objects being
leaked.  Whoops.

llvm-svn: 10599
 2003-12-23 22:18:36 +00:00
Chris Lattner 601415ed84 Do not delete the type holder until after the call instruction has been 
constructed!
