* Invert these branches by default, it makes assembly comparisons a littleEric Christopher2010-11-031-2/+2

* The MC code couldn't handle ARM LDR instructions with negative offsets:Bill Wendling2010-11-037-53/+160
| | | | | | | | | | | | | vldr.64 d1, [r0, #-32] The problem was with how the addressing mode 5 encodes the offsets. This change makes sure that the way offsets are handled in addressing mode 5 is consistent throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue" method into an "Imm12" and "addressing mode 5" version. But not to worry! The majority of the duplicated code has been unified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118144 91177308-0d34-0410-b5e6-96231b3b80d8

* Two sets of changes. Sorry they are intermingled.Evan Cheng2010-11-0317-166/+297
| | | | | | | | | | | | | | 1. Fix pre-ra scheduler so it doesn't try to push instructions above calls to "optimize for latency". Call instructions don't have the right latency and this is more likely to use introduce spills. 2. Fix if-converter cost function. For ARM, it should use instruction latencies, not # of micro-ops since multi-latency instructions is completely executed even when the predicate is false. Also, some instruction will be "slower" when they are predicated due to the register def becoming implicit input. rdar://8598427 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118135 91177308-0d34-0410-b5e6-96231b3b80d8

Mark a bunch of ARM instructions that use this as isCodeGenOnly.
