2011-09-06Add codegen support for vector select (in the IR this means a selectDuncan Sands
with a vector condition); such selects become VSELECT codegen nodes. This patch also removes VSETCC codegen nodes, unifying them with SETCC nodes (codegen was actually often using SETCC for vector SETCC already). This ensures that various DAG combiner optimizations kick in for vector comparisons. Passes dragonegg bootstrap with no testsuite regressions (nightly testsuite as well as "make check-all"). Patch mostly by Nadav Rotem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139159 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-06Fix fall outs from my recent change on how carry bit is modeled during isel.Evan Cheng
Now the 'S' instructions, e.g. ADDS, treat S bit as optional operand as well. Also fix isel hook to correctly set the optional operand. rdar://10073745 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139157 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-06ARM .code directive should always go to the streamer.Jim Grosbach
Even if there's no mode switch performed, the .code directive should still be sent to the output streamer. Otherwise, for example, an output asm stream is not equivalent to the input stream which generated it (a dependency on the input target triple arm vs. thumb is introduced which was not originally there). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139155 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-06Split the init.trampoline intrinsic, which currently combines GCC'sDuncan Sands
init.trampoline and adjust.trampoline intrinsics, into two intrinsics like in GCC. While having one combined intrinsic is tempting, it is not natural because typically the trampoline initialization needs to be done in one function, and the result of adjust trampoline is needed in a different (nested) function. To get around this llvm-gcc hacks the nested function lowering code to insert an additional parent variable holding the adjust.trampoline result that can be accessed from the child function. Dragonegg doesn't have the luxury of tweaking GCC code, so it stored the result of adjust.trampoline in the memory GCC set aside for the trampoline itself (this is always available in the child function), and set up some new memory (using an alloca) to hold the trampoline. Unfortunately this breaks Go which allocates trampoline memory on the heap and wants to use it even after the parent has exited (!). Rather than doing even more hacks to get Go working, it seemed best to just use two intrinsics like in GCC. Patch mostly by Sanjoy Das. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@139140 91177308-0d34-0410-b5e6-96231b3b80d8
