Use opt -S instead of piping bitcode output through llvm-dis. llvm-svn: 81257 2009-09-09 00:34:10 +02:00			`; RUN: opt %s -instcombine -S > %t`
canonicalize inttoptr and ptrtoint instructions which cast pointers to/from integer types that are not intptr_t to convert to intptr_t then do an integer conversion to the dest type. This exposes the cast to the optimizer. llvm-svn: 67638 2009-03-24 19:35:40 +01:00
