Chris Lattner 7d83ebcadd Make blockaddress(@func, null) be valid, and make 'deleting a basic ... block with a blockaddress still referring to it' replace the invalid blockaddress with a new blockaddress(@func, null) instead of a inttoptr(1). This changes the bitcode encoding format, and still needs codegen support (this should produce a non-zero value, referring to the entry block of the function would also be quite reasonable). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85678 91177308-0d34-0410-b5e6-96231b3b80d8		2009-10-31 20:08:37 +00:00
