Combiner-AA improvements, why not on by default?
Pre-regalloc tail duplication
x86 sibcall / tailcall optimization in CCC mode.
New LSR with full strength reduction mode
The most awesome sext / zext optimization pass. ?
New LSR with "full strength reduction" mode. Description?
Codegen level OptimizeExtsPass pass, takes advantage of x86 subregs.
Better code size analysis in loop unswitch, inliner code split out to a new
CodeMetrics class for reuse.
The ARM backend now has good support for ARMv4 backend (tested on StrongARM
hardware), previously only supported ARMv4T and newer.
Half-float support in APFloat
Indirect branch + address of label (blog post), particularly useful for interpreters.
Many changes to the pass ordering for improved optimization effectiveness.
Many changes to the pass ordering for improved optimization effectiveness.
BasicAA improved to be less dependent on "type safe" pointers, it can now look
through bitcasts more aggressively.

PostRA scheduler for X86?
llvm.dbg.value, not being used by default though, more in 2.8. Many improvements to debug info

New MicroBlaze backend. http://en.wikipedia.org/wiki/MicroBlaze
XMM subreg modeling for extraction of the low element.
Opt now works conservatively if no target data is set (is this fully working?)
Target data now has notion of 'native' integer data types which optimizations can use.

AndersAA got removed (from 2.7 or mainline?)
PredSimplify, LoopVR, GVNPRE got removed.
Defaults to RTTI off (smaller code size!), packagers should build with make REQUIRE_RTTI=1.

PredSimplify, LoopVR, GVNPRE, RSProfiling (random sampling profiling) got removed.
LLVM command line tools now overwrite their output, before they would only do this with -f.
DOUT removed, use DEBUG(errs() instead.
Much stuff converted to use raw_ostream instead of std::ostream.
