| | | | | | | | | | consider it to be readonly. In fact, don't even consider it to be readonly if it does a volatile load from an AllocaInst either (it is debatable as to whether readonly would be correct or not in this case; play safe for the moment).

* Overhaul memory barriers in the ARM backend. Radar 8601999.Bob Wilson2010-10-307-145/+89
| | | | | | | | | | | | | | | | | | | There were a number of issues to fix up here: * The "device" argument of the llvm.memory.barrier intrinsic should be used to distinguish the "Full System" domain from the "Inner Shareable" domain. It has nothing to do with using DMB vs. DSB instructions. * The compiler should never need to emit DSB instructions. Remove the ARMISD::SYNCBARRIER node and also remove the instruction patterns for DSB. * Merge the separate DMB/DSB instructions for options only used for the disassembler with the default DMB/DSB instructions. Add the default "full system" option ARM_MB::SY to the ARM_MB::MemBOpt enum. * Add a separate ARMISD::MEMBARRIER_MCR node for subtargets that implement a data memory barrier using the MCR instruction. * Fix up encodings for these instructions (except MCR). I also updated the tests and added a few new ones to check for DMB options that were not currently being exercised. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@117756 91177308-0d34-0410-b5e6-96231b3b80d8
* Add polly support to the build system.Tobias Grosser2010-10-305-9/+74
| | | | | | | | | | | | | Update the cmake and autoconf build system to compile polly as a shared library if it is checked out into tools/polly. In case polly is not checked out, nothing changes. This models the way clang can be added to llvm if checked out to tools/clang. Also rebuild configure.
