* Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a stepEvan Cheng2011-01-132-9/+4
| | | | | | | | in the right direction. It eliminated some hacks and will unblock codegen work. But it's far from being done. It doesn't reject illegal expressions, e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all. llvm-svn: 123369

| | | | | | | | R_ARM_MOVT_PREL and R_ARM_MOVW_PREL_NC. 2. Fix minor bug in ARMAsmPrinter - treat bitfield flag as a bitfield, not an enum. 3. Add support for 3 new elf section types (no-ops) llvm-svn: 123294

* GCC objects to the two sides of a conditional expression having different enumMatt Beaumont-Gay2010-12-211-2/+2

* Don't relax org or align. They change size as the relaxation happens, but theyRafael Espindola2010-12-211-42/+27
