[LLVMdev] Difficulty with reusing DAG nodes.
...ceUses(N.getValue(0), SDValue(Lo,0)); if (!N.getValue(1).use_empty()) ReplaceUses(N.getValue(1), SDValue(Hi,0)); return NULL; } The code generator complains: nios2-elf-ecc: /home/rich/llvm-trunk-new/lib/CodeGen/SelectionDAG/ScheduleDAG.cpp:141: void llvm::ScheduleDAG::BuildSchedUnits(): Assertion `N->getNodeId() == -1 && "Node already inserted!"' failed I'm guessing that's because I'm reusing Op1 and Op2. What is the right way to reuse DAG operands? -Rich

[LLVMdev] Tail-calling
Tail calls through function pointers should work.If not please send a testcase. I just added the two examples from the bug (1392) that calls for true tail call support. They work on my machine (-tailcallopt needs to be enabled) ;) That would be commit 56127. regards On Thu, Sep 11, 2008 at 11:21 PM, Evan Cheng <evan.cheng at apple.com> wrote: > Arnold implemented tail call.
