2009-11-11Don't trivially delete unused calls to llvm.invariant.start. This allowsDuncan Sands
llvm.invariant.start to be used without necessarily being paired with a call to llvm.invariant.end. If you run the entire optimization pipeline then such calls are in fact deleted (adce does it), but that's actually a good thing since we probably do want them to be zapped late in the game. There should really be an integration test that checks that the llvm.invariant.start call lasts long enough that all passes that do interesting things with it get to do their stuff before it is deleted. But since no passes do anything interesting with it yet this will have to wait for later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86840 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-11The TBB and TBH instructions for Thumb2 are really handy for jump tables, butJim Grosbach
can only branch forward. To best take advantage of them, we'd like to adjust the basic blocks around a bit when reasonable. This patch puts basics in place to do that, with a super-simple algorithm for backwards jump table targets that creates a new branch after the jump table which branches backwards. Real heuristics for reordering blocks or other modifications rather than inserting branches will follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86791 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-10Modify how the prologue encoded the "move" information for the FDE. GCCBill Wendling
generates a sequence similar to this: __Z4funci: LFB2: mflr r0 LCFI0: stmw r30,-8(r1) LCFI1: stw r0,8(r1) LCFI2: stwu r1,-80(r1) LCFI3: mr r30,r1 LCFI4: where LCFI3 and LCFI4 are used by the FDE to indicate what the FP, LR, and other things are. We generated something more like this: Leh_func_begin1: mflr r0 stw r31, 20(r1) stw r0, 8(r1) Llabel1: stwu r1, -80(r1) Llabel2: mr r31, r1 Note that we are missing the "mr" instruction. This patch makes it more like the GCC output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@86729 91177308-0d34-0410-b5e6-96231b3b80d8
