[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?

[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.
