Evan Cheng a5e595d23a If two instructions are both two-address code, favors (schedule closer to 
terminator) the one that has a CopyToReg use. This fixes
2006-05-11-InstrSched.ll with -new-cc-modeling-scheme.

Rafael Espindola 6c04ac1db0 Refactor the memcpy lowering for the x86 target. 
The only generated code difference is that now we call memcpy when
the size of the array is unknown. This matches GCC behavior and is
better since the run time value can be arbitrarily large.

Dan Gohman a1d46c7d0a TargetAsmInfo::getAddressSize() was incorrect for x86-64 and 64-bit targets 
other than PPC64. Instead of fixing it, just remove it and fix all the
places that use it to use TargetData::getPointerSize() instead, as there
aren't very many. Most of the references were in DwarfWriter.cpp.

Gordon Henriksen 613afce430 CollectorMetadata abstractly describes stack maps for a function. 
It includes:

 - location and of each safe point in machine code (identified by a
   label)
 - location of each root within the stack frame (identified by an
   offset), including the metadata tag provided to llvm.gcroot in
   the user program
 - size of the stack frame (for collectors which want to cheat on
   stack crawling :)
 - and eventually will include liveness

It is to be populated by back-ends during code-generation.

CollectorModuleMetadata aggregates this information across the
entire module.

Gordon Henriksen 658c57eb66 My previous Registry.h header, as well as Collectors.h, which is the 
registry for dynamically-loaded garbage collection compiler plugins.

Gordon Henriksen 0076a6727e GarbageCollection.html is expanded to encompass the coming 
capabilities. This is a major rewrite and is easier to read en toto
rather than patchwise.

 2007-09-26 21:38:03 +00:00
Evan Cheng 8e136a9dc4 - Move getPhysicalRegisterRegClass() from ScheduleDAG to MRegisterInfo. 
- Added ability to emit cross class register copies to the BBRU scheduler.
- More aggressive backtracking.

llvm-svn: 42373
 2007-09-26 21:33:42 +00:00
Evan Cheng 8728c3376a - Added MRegisterInfo::getCrossCopyRegClass() hook. For register classes where reg to reg copies are not possible, this returns another register class which registers in the specified register class can be copied to (and copy back from). 
- X86 copyRegToReg() now supports copying between EFLAGS and GR32 / GR64 registers.
