2009-07-30I've changed the semantics of MERGE_VALUES a bit. It's now allowed to live ↵Evan Cheng
until scheduling. It's deleted when the scheduler translate DAG nodes to machine instructions. This is currently used by X86 to handle atomic_load_add when the output of the node is not used. I believe there is a better solution. But I find MERGE_VALUES useful for selecting multi-output node when the dead output can be selected as a IMPLICIT_DEF. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77583 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-30Optimize some common usage patterns of atomic built-ins ↵Evan Cheng
__sync_add_and_fetch() and __sync_sub_and_fetch. When the return value is not used (i.e. only care about the value in the memory), x86 does not have to use add to implement these. Instead, it can use add, sub, inc, dec instructions with the "lock" prefix. This is currently implemented using a bit of instruction selection trick. The issue is the target independent pattern produces one output and a chain and we want to map it into one that just output a chain. The current trick is to select it into a merge_values with the first definition being an implicit_def. The proper solution is to add new ISD opcodes for the no-output variant. DAG combiner can then transform the node before it gets to target node selection. Problem #2 is we are adding a whole bunch of x86 atomic instructions when in fact these instructions are identical to the non-lock versions. We need a way to add target specific information to target nodes and have this information carried over to machine instructions. Asm printer (or JIT) can use this information to add the "lock" prefix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77582 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-30Switch obvious clients to Twine instead of utostr (when they were already usingDaniel Dunbar
a Twine, e.g., for names). - I am a little ambivalent about this; we don't want the string conversion of utostr, but using overload '+' mixed with string and integer arguments is sketchy. On the other hand, this particular usage is something of an idiom. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77579 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-291. Introduce a new TargetOperandInfo::getRegClass() helper methodChris Lattner
and convert code to using it, instead of having lots of things poke the isLookupPtrRegClass() method directly. 2. Make PointerLikeRegClass contain a 'kind' int, and store it in the existing regclass field of TargetOperandInfo when the isLookupPtrRegClass() predicate is set. Make getRegClass pass this into TargetRegisterInfo::getPointerRegClass(), allowing targets to have multiple ptr_rc things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77504 91177308-0d34-0410-b5e6-96231b3b80d8
