* Commit a new LoopStrengthReduce pass that can use scalar evolutions andNate Begeman2005-07-301-179/+517
| | | | | | | | target data to decide which loop induction variables to strength reduce and how to do so. This work is mostly by Chris Lattner, with tweaks by me to get it working on some of MultiSource. llvm-svn: 22558

* Like constants, globals on some platforms are GOT relative. This means they ↵Andrew Lenharth2005-07-283-14/+84
| | | | | | | | | | | | | | have to be allocated near the GOT, which new doesn't do. So break out the allocate into a new function. Also move GOT index handling into JITResolver. This lets it update the mapping when a Lazy function is JITed. It doesn't managed the table, just the mapping. Note that this is still non-ideal, as any function that takes a function address should also take a GOT index, but that is a lot of changes. The relocation resolve process updates any GOT entry it sees is out of date. llvm-svn: 22537
