* Enable first-class aggregates support.Dan Gohman2008-07-231-3/+1
| | | | | | | | | | | | | Remove the GetResultInst instruction. It is still accepted in LLVM assembly and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove support for return instructions with multiple values. These are auto-upgraded to use InsertValueInst instructions. The IRBuilder still accepts multiple-value returns, and auto-upgrades them to InsertValueInst instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53941 91177308-0d34-0410-b5e6-96231b3b80d8
* Use a CallSite to find the nth argument of a call/invoke instruction instead ofMatthijs Kooijman2008-06-191-11/+11

* Learn IPConstProp to propagate arguments that are directly returned. StrictlyMatthijs Kooijman2008-06-171-2/+11
| | | | | | | | | | speaking these are not constant values. However, when a function always returns one of its arguments, then from the point of view of each caller the return value is constant (or at least a known value) and can be replaced. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52397 91177308-0d34-0410-b5e6-96231b3b80d8
* Learn IPConstProp to look at individual return values and propagate themMatthijs Kooijman2008-06-171-53/+76
| | | | | | | | | | | | individually. Also learn IPConstProp how returning first class aggregates work, in addition to old style multiple return instructions. Modify the return-constants testscase to confirm this behaviour. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52396 91177308-0d34-0410-b5e6-96231b3b80d8
