Chris Lattner	1c0af0ed25	fix PR8602, a bug in an assertion: a volatile store *of* a pointer ... does not make the alias set for that pointer volatile, just stores *to* the pointer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122171 91177308-0d34-0410-b5e6-96231b3b80d8	2010-12-19 05:51:54 +00:00
Chris Lattner	7abdb22e52	fix PR8102, a case where we'd copyValue from a value that we already ... deleted. Fix this by doing the copyValue's before we delete stuff! The testcase only repros the problem on my system with valgrind. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113820 91177308-0d34-0410-b5e6-96231b3b80d8	2010-09-14 00:19:00 +00:00

Chris Lattner	469996400c	fix a bug in my licm rewrite when a load from the promoted memory ... location is being re-stored to the memory location. We would get a dangling pointer from the SSAUpdate data structure and miss a use. This fixes PR8068 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113042 91177308-0d34-0410-b5e6-96231b3b80d8	2010-09-04 00:12:30 +00:00
