2011-10-17Correct over-zealous removal of hack.Bill Wendling
Some code want to check that *any* call within a function has the 'returns twice' attribute, not just that the current function has one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142221 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-13Handle the case of a tail recursion in which the tail call is followedDuncan Sands
by a return that returns a constant, while elsewhere in the function another return instruction returns a different constant. This is a special case of accumulator recursion, so just generalize the existing logic a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@108241 91177308-0d34-0410-b5e6-96231b3b80d8
2010-06-26Fix PR7328: when turning a tail recursion into a loop, need to preserveDuncan Sands
the returned value after the tail call if it differs from other return values. The optimal thing to do would be to introduce a phi node for the return value, but for the moment just fix the miscompile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@106947 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-16Refine the detection of seemingly infinitely recursive calls where theDan Gohman
callee is expected to be expanded to something else by codegen, so that normal infinitely recursive calls are still transformed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101468 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-31Do not mark no-return calls tail calls. It'll screw up special calls like ↵Evan Cheng
longjmp and it doesn't make much sense for performance reason. If my logic is faulty, please let me know. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94937 91177308-0d34-0410-b5e6-96231b3b80d8

2006-12-31For PR950:Reid Spencer
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
