Vikram S. Adve bbf45f6960 Added class MachineOptInfo as interface to target-specific 
routines supporting machine code optimization.
Also added method MachineInstrInfo::getNOPOpCode().

 2002-09-20 00:47:49 +00:00
Vikram S. Adve e008b2d62e Allow copy coalescing in more cases: if sum of node degrees is more than 
than #available regs, compute the sum excluding duplicates and if that
is less than #regs, go ahead and coalesce.
Add method IGNode::getCombinedDegree to count excluding duplicates.

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.

Chris Lattner 4e6598b325 Reenable these options because they break testing on sparc without them. 
Conditionalizing them on DISABLE_LLC means they aren't enabled under linux.

Chris Lattner 1e860c917a Native CC compiler has the same problem as CXX compiler.

Chris Lattner 67b9d7f7a9 Workaround for bug in GCC 3.1.1 iostreams library on sparc. It apprarently 
isn't flushing an ostream when it is deleted.

llvm-svn: 3834

Chris Lattner 9ae5cf5ca3 Minor non-functionality changing changes.

Chris Lattner 681bf7bbcc * Burg is no longer configured in Makefile.config 
* CXX now is configured in Makefile.config (optionally)
* The GCC command is now no longer bin/gcc, it's bin/llvm-gcc
* Minor cleanups

Chris Lattner 81c8476242 Platform specific makefiles specify where to find the GCC frontend for their 
architecture.  The location of the GCC frontend may be overridden by the
Makefile.config file.

llvm-svn: 3830
 2002-09-19 19:44:28 +00:00
Chris Lattner b6504001f0 * Move the burg option into Makefile.common, since it is no longer configurable 
* Makefile.config now should only specify the location of the gcc frontend if it
  is not in the place specified by the platform makefile.

 2002-09-19 19:43:29 +00:00
Chris Lattner c58930c52c Move the burg option out of Makefile.config into Makefile.common since 
it no longer needs to be configured.

Chris Lattner 1550ba2bc5 Add an optimization to support the most common access pattern for the 
library.  This speeds debug builds up significantly.

Chris Lattner 31a9e81713 Switch over to using the x86 version of the C frontend, by default.

 2002-09-19 19:21:18 +00:00
Chris Lattner 5a67f4725e It turns out that the cannonical name for the llvm-gcc compiler is, well 
llvm-gcc, not gcc.

 2002-09-19 16:54:57 +00:00
Chris Lattner a450397247 Make sure that we abort if an error happens as early as neccesary. Before 
it was possible for the passmanager to continue running passes after the
verifier even if the module was not well formed.

Vikram S. Adve 7369140fee Fix to work in new location (utils/) and to use gmake instead of gnumake 
since gnumake doesn't exist on our new spiffy Linux machines.

Vikram S. Adve 9c485d2165 gcc3.1.1 seems much more selective about what it loads from archives, and 
does not link in many passes that are loaded by gcc2.95.3.  So use object
files instead of archives in many more cases.
