| | | | | | | | bits known clear in the result and don't care about the # casts eliminated. TD is also dead but keeping it for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93098 91177308-0d34-0410-b5e6-96231b3b80d8
* two changes: Chris Lattner2010-01-102-25/+53
| | | | | | | | | | | | 1) don't try to optimize a sext or zext that is only used by a trunc, let the trunc get optimized first. This avoids some pointless effort in some common cases since instcombine scans down a block in the first pass. 2) Change the cost model for zext elimination to consider an 'and' cheaper than a zext. This allows us to do it more aggressively, and for the next patch to simplify the code quite a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93097 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixed linking of modules containing aliases to constant bitcasts. Existing ↵David Chisnall2010-01-091-5/+16
| | | | | | | | | | behaviour first tried to replace the aliases with the global that they aliased (rather than the bitcast), causing a crash on an assert because the types didn't match. When this was fixed, it then did the same thing creating the new alias (creating an alias with a different type to its aliasee). Linking modules containing aliases to GEPs is still not quite right. GEPs that are equivalent to bitcasts will be replaced by bitcasts, GEPs that are not will just break. Aliases to GEPs that are not equivalent to bitcasts are horribly broken anyway (it might be worth adding an assert when creating the alias to prevent these being created; they just cause problems later). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93052 91177308-0d34-0410-b5e6-96231b3b80d8
