2010-11-10Simplify and clean up MC symbol lookup for ARM constant pool values. This fixesJim Grosbach
double quoting of ObjC symbol names in constant pool entries. rdar://8652107 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118688 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-10Simplify binary operations where one operand is a select instruction.Duncan Sands
The simplifications performed here never create new instructions, they only return existing instructions (or a constant), and so are always a win. In theory they should transform (for example) %z = and i32 %x, %y %s = select i1 %cond, i32 %y, i32 %z %r = and i32 %x, %s into %r = and i32 %x, y but in practice they get into a fight with instcombine, and lose. Unfortunately instcombine does a poor job in this case. Nonetheless I'm committing this transform to make it easier to discuss what to do to make peace with instcombine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118679 91177308-0d34-0410-b5e6-96231b3b80d8

not check by FILE_TYPE_CHAR. It must be better to check it with Console API. The special file "NUL" is FILE_TYPE_CHAR with GetFileType(h). It was treated as display device and discarding output to NUL had failed. (eg. opt -o nul) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118678 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-09Define the subtarget feature for the architecture version,Bob Wilson

2010-11-09Do not use MEMBARRIER_MCR for any Thumb code.Bob Wilson
It is only supported for ARM code. Normally Thumb2 code would use DMB instead, but depending on how the compiler is invoked (e.g., -mattr=-db) that might be disabled. This prevents a "cannot select MEMBARRIER_MCR" error in that situation. Radar 8644195 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118642 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-09Two types of instructions have register lists:Bill Wendling
* LDM, et al, uses a bit mask to indicate the register list. * VLDM, et al, uses a base register plus number. The LDM instructions may be non-contiguous, but the VLDM ones must be contiguous. Those are semantic checks that should be done later in the compiler. Also postpone the creation of the bit mask until it's needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118640 91177308-0d34-0410-b5e6-96231b3b80d8
