* Treat EntryToken nodes as "passive" so that they aren't added to theDan Gohman2008-04-155-37/+54
| | | | | | | | | | | | | | | | | | ScheduleDAG; they don't correspond to any actual instructions so they don't need to be scheduled. This fixes a bug where the EntryToken was being scheduled multiple times in some cases, though it ended up not causing any trouble because EntryToken doesn't expand into anything. With this fixed the schedulers reliably schedule the expected number of units, so we can check this with an assertion. This requires a tweak to test/CodeGen/X86/loop-hoist.ll because it ends up getting scheduled differently in a trivial way, though it was enough to fool the prcontext+grep that the test does. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49701 91177308-0d34-0410-b5e6-96231b3b80d8

* This patch corrects the handling of byval arguments for tailcallArnold Schwaighofer2008-04-124-30/+182
| | | | | | | | | | | | | | | | | | | | | | | | optimized x86-64 (and x86) calls so that they work (... at least for my test cases). Should fix the following problems: Problem 1: When i introduced the optimized handling of arguments for tail called functions (using a sequence of copyto/copyfrom virtual registers instead of always lowering to top of the stack) i did not handle byval arguments correctly e.g they did not work at all :). Problem 2: On x86-64 after the arguments of the tail called function are moved to their registers (which include ESI/RSI etc), tail call optimization performs byval lowering which causes xSI,xDI, xCX registers to be overwritten. This is handled in this patch by moving the arguments to virtual registers first and after the byval lowering the arguments are moved from those virtual registers back to RSI/RDI/RCX. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49584 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | | | on any current target and aren't optimized in DAGCombiner. Instead of using intermediate nodes, expand the operations, choosing between simple loads/stores, target-specific code, and library calls, immediately. Previously, the code to emit optimized code for these operations was only used at initial SelectionDAG construction time; now it is used at all times. This fixes some cases where rep;movs was being used for small copies where simple loads/stores would be better. This also cleans up code that checks for alignments less than 4; let the targets make that decision instead of doing it in target-independent code. This allows x86 to use rep;movs in low-alignment cases. Also, this fixes a bug that resulted in the use of rep;stos for memsets of 0 with non-constant memory size when the alignment was at least 4. It's better to use the library in this case, which can be significantly faster when the size is large. This also preserves more SourceValue information when memory intrinsics are lowered into simple loads/stores. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49572 91177308-0d34-0410-b5e6-96231b3b80d8
