* Testcase for PR1638.Bill Wendling2008-10-151-0/+27
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57590 91177308-0d34-0410-b5e6-96231b3b80d8
* - Add target lowering hooks that specify which setcc conditions are illegal,Evan Cheng2008-10-151-0/+11
| | | | | | | | | | | | i.e. conditions that cannot be checked with a single instruction. For example, SETONE and SETUEQ on x86. - Teach legalizer to implement *illegal* setcc as a and / or of a number of legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ. - Move x86 target over. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57542 91177308-0d34-0410-b5e6-96231b3b80d8
* When doing the very-late shift-and address-mode optimization,Dan Gohman2008-10-131-0/+38
| | | | | | | | | | | | | | | create a new DAG node to represent the new shift to keep the DAG consistent, even though it'll almost always be folded into the address. If a user of the resulting address has multiple uses, the nodes may get revisited by a later MatchAddress call, in which case DAG inconsistencies do matter. This fixes PR2849. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57465 91177308-0d34-0410-b5e6-96231b3b80d8
