* Fix SCCP's handling of struct value loads and stores. SCCP doesn'tDan Gohman2008-08-131-0/+20
| | | | | | | | track individual leaf values in such cases, so it needs to treat struct values as normal values in this case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@54760 91177308-0d34-0410-b5e6-96231b3b80d8
* Enable first-class aggregates support.Dan Gohman2008-07-231-2/+5
| | | | | | | | | | | | | 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

* For PR950:Reid Spencer2006-12-315-6/+6
| | | | | | | | | | | | | | | | | | | | | | | Update the test suite to accommodate the change from signed integer types to signless integer types. The changes were of only a few kinds: 1. Make sure llvm-upgrade is run on the source which does the bulk of the changes automatically. 2. Change things like "grep 'int'" to "grep 'i32'" 3. In several tests bitcasting caused the same name to be reused in the same type plane. These had to be manually fixed. The fix was (generally) to leave the bitcast and provide the instruction with a new name. This should not affect the semantics of the test. In a few cases, the bitcasts were known to be superfluous and irrelevant to the test case so they were removed. 4. One test case uses a bytecode file which needed to be updated to the latest bytecode format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32789 91177308-0d34-0410-b5e6-96231b3b80d8
