Owen Anderson 27fb3dcbc7 Make TargetInstrInfo::copyRegToReg return a bool indicating whether the copy requested
was inserted or not.  This allows bitcast in fast isel to properly handle the case
where an appropriate reg-to-reg copy is not available.

Owen Anderson 4f6bf04616 Convert uses of std::vector in TargetInstrInfo to SmallVector. This change had to be propoagated down into all the targets and up into all clients of this API.
llvm-svn: 54802
2008-08-14 22:49:33 +00:00
Owen Anderson 30cc028e4a Make LiveVariables even more optional, by making it optional in the call to TargetInstrInfo::convertToThreeAddressInstruction
Also, if LV isn't around, then TwoAddr doesn't need to be updating flags, since they won't have been set in the first place.

Dan Gohman eabd647cd5 Change target-specific classes to use more precise static types.
This eliminates the need for several awkward casts, including
the last dynamic_cast under lib/Target.

Evan Cheng 3b3286d4bc It's not always safe to fold movsd into xorpd, etc. Check the alignment of the load address first to make sure it's 16 byte aligned.

Owen Anderson 2a3be7bb6c Move even more functionality from MRegisterInfo into TargetInstrInfo.
Some day I'll get it all moved over...

Chris Lattner 25568e4cef Fix a problem where lib/Target/TargetInstrInfo.h would include and use
a header file from libcodegen.  This violates a layering order: codegen
depends on target, not the other way around.  The fix to this is to 
split TII into two classes, TII and TargetInstrInfoImpl, which defines
stuff that depends on libcodegen.  It is defined in libcodegen, where 
the base is not.

Owen Anderson 7a73ae9a86 Move copyRegToReg from MRegisterInfo to TargetInstrInfo. This is part of the

Dan Gohman e8c1e428f2 Revert the earlier change that removed the M_REMATERIALIZABLE machine
instruction flag, and use the flag along with a virtual member function
hook for targets to override if there are instructions that are only
trivially rematerializable with specific operands (i.e. constant pool
loads).

llvm-svn: 37728
2007-06-26 00:48:07 +00:00
Dan Gohman 9e82064924 Replace M_REMATERIALIZIBLE and the newly-added isOtherReMaterializableLoad
with a general target hook to identify rematerializable instructions. Some
instructions are only rematerializable with specific operands, such as loads
from constant pools, while others are always rematerializable. This hook
allows both to be identified as being rematerializable with the same
mechanism.
