2011-08-03ARM refactoring assembly parsing of memory address operands.Jim Grosbach
Memory operand parsing is a bit haphazzard at the moment, in no small part due to the even more haphazzard representations of memory operands in the .td files. Start cleaning that all up, at least a bit. The addressing modes in the .td files will be being simplified to not be so monolithic, especially with regards to immediate vs. register offsets and post-indexed addressing. addrmode3 is on its way with this patch, for example. This patch is foundational to enable going back to smaller incremental patches for the individual memory referencing instructions themselves. It does just enough to get the basics in place and handle the "make check" regression tests we already have. Follow-up work will be fleshing out the details and adding more robust test cases for the individual instructions, starting with ARM mode and moving from there into Thumb and Thumb2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136845 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-03An algorithm for incrementally updating LoopInfo within aAndrew Trick
LoopPassManager. The incremental update should be extremely cheap in most cases and can be used in places where it's not feasible to regenerate the entire loop forest. - "Unloop" is a node in the loop tree whose last backedge has been removed. - Perform reverse dataflow on the block inside Unloop to propagate the nearest loop from the block's successors. - For reducible CFG, each block in unloop is visited exactly once. This is because unloop no longer has a backedge and blocks within subloops don't change parents. - Immediate subloops are summarized by the nearest loop reachable from their exits or exits within nested subloops. - At completion the unloop blocks each have a new parent loop, and each immediate subloop has a new parent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136844 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-03Enable compact region splitting by default.Jakob Stoklund Olesen
This helps generate better code in functions with high register pressure. The previous version of compact region splitting caused regressions because the regions were a bit too large. A stronger negative bias applied in r136832 fixed this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136836 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-03Be more conservative when forming compact regions.Jakob Stoklund Olesen
Apply twice the negative bias on transparent blocks when computing the compact regions. This excludes loop backedges from the region when only one of the loop blocks uses the register. Previously, we would include the backedge in the region if the loop preheader and the loop latch both used the register, but the loop header didn't. When both the header and latch blocks use the register, we still keep it live on the backedge. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136832 91177308-0d34-0410-b5e6-96231b3b80d8
