2011-10-24ARM refactor am6offset usage for VLD1.Jim Grosbach
Split am6offset into fixed and register offset variants so the instruction encodings are explicit rather than relying an a magic reg0 marker. Needed to being able to parse these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142853 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-24Fix a NEON disassembly case that was broken in the recent refactorings. As ↵Owen Anderson
more of this code gets refactored, a lot of these manual decoding hooks should get smaller and/or go away entirely. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142817 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-21ARM VLD parsing and encoding.Jim Grosbach
Next step in the ongoing saga of NEON load/store assmebly parsing. Handle VLD1 instructions that take a two-register register list. Adjust the instruction definitions to only have the single encoded register as an operand. The super-register from the pseudo is kept as an implicit def, so passes which come after pseudo-expansion still know that the instruction defines the other subregs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142670 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-19Use literal pool loads instead of MOVW/MOVT for materializing global ↵James Molloy
addresses when optimizing for size. On spec/gcc, this caused a codesize improvement of ~1.9% for ARM mode and ~4.9% for Thumb(2) mode. This is codesize including literal pools. The pools themselves doubled in size for ARM mode and quintupled for Thumb mode, leaving suggestion that there is still perhaps redundancy in LLVM's use of constant pools that could be decreased by sharing entries. Fixes PR11087. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142530 91177308-0d34-0410-b5e6-96231b3b80d8
