* Optimize some common usage patterns of atomic built-ins ↵Evan Cheng2009-07-305-14/+280
| | | | | | | | | | | | | __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
* Switch obvious clients to Twine instead of utostr (when they were already usingDaniel Dunbar2009-07-301-2/+1
| | | | | | | | | | 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

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
