2010-11-09Define the subtarget feature for the architecture version,Bob Wilson
as derived from the target triple. This is important for enabling features that are implied based on the architecture version. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118643 91177308-0d34-0410-b5e6-96231b3b80d8
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

2010-11-09Add support for a few simple fixups to the ARM Darwin asm backend. This allowsJim Grosbach
constant pool references and global variable refernces to resolve properly for object file generation.
