2006-03-05Split the list scheduler into top-down and bottom-up pieces. The priorityChris Lattner
function of the top-down scheduler are completely bogus currently, and having (future) PPC specific in this file is also wrong, but this is a small incremental step. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26552 91177308-0d34-0410-b5e6-96231b3b80d8
2006-03-05Add a new scheduling type. This is, of course, a hack. Proper factoringChris Lattner
will come later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26551 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-04MEMSET / MEMCPY lowering bugs: we can't issue a single WORD / DWORD version ofEvan Cheng
rep/stos and rep/mov if the count is not a constant. We could do rep/stosl; and $count, 3; rep/stosb For now, I will lower them to memset / memcpy calls. We will revisit this after a little bit experiment. Also need to take care of the trailing bytes even if the count is a constant. Since the max. number of trailing bytes are 3, we will simply issue loads / stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@26517 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-04Be more conservative with our symbolic alias analysis. In particular,Chris Lattner
don't assume that A[1][0] and A[0][i] can't alias. "i" might be out of range, or even negative. This fixes a miscompilation of 188.ammp (which does bad pointer tricks) with the new CFE.
