2013-04-04Avoid high-latency false CPSR dependencies even for tMOVSi.Jakob Stoklund Olesen
The Thumb2SizeReduction pass avoids false CPSR dependencies, except it still aggressively creates tMOVi8 instructions because they are so common. Avoid creating false CPSR dependencies even for tMOVi8 instructions when the the CPSR flags are known to have high latency. This allows integer computation to overlap floating point computations. Also process blocks in a reverse post-order and propagate high-latency flags to successors. <rdar://problem/13468102> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178773 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18Disable ARM partial flag dependency optimization at -OzQuentin Colombet
To not over constrain the scheduler for ARM in thumb mode, some optimizations for code size reduction, specific to ARM thumb, are blocked when they add a dependency (like write after read dependency). Disables this check when code size is the priority, i.e., code is compiled with -Oz. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170462 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-24Thumb2 size reduction fix for tied operands of tMUL.Jim Grosbach
The tied source operand of tMUL is the second source operand, not the first like every other two-address thumb instruction. Special case it in the size reduction pass to make sure we create the tMUL instruction properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151315 91177308-0d34-0410-b5e6-96231b3b80d8
