| | | | | | | | | | | | | overly long ints, e.g. i96, into pieces at PHIs and the nodes that feed into them; however big-endian reverses the order of the pieces (for some reason), and wasn't doing it the same way on both sides, so the pieces didn't match and runtime failures ensued.

* Clean up dwarf writer, part 1. This eliminated the horrible recursive ↵Evan Cheng2009-02-25

It eliminated use of slow UniqueVector and replaced it with StringMap, SmallVector, and DenseMap, etc. It also fixed some non-deterministic behavior.

* Overhaul my earlier submission due to feedback. It's a large patch, but most ofBill Wendling2009-02-24
| | | | | | | | | | | | | them are generic changes. - Use the "fast" flag that's already being passed into the asm printers instead of shoving it into the DwarfWriter. - Instead of calling "MI->getParent()->getParent()" for every MI, set the machine function when calling "runOnMachineFunction" in the asm printers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65379 91177308-0d34-0410-b5e6-96231b3b80d8

We want to fall back to the original way of emitting debug info when we're in -O0/-fast mode. - Add plumbing in to pass the "Fast" flag to places that need it. - XFAIL DebugInfo/deaddebuglabel.ll.
