[LLVMdev] Difficulty with reusing DAG nodes.
I'm trying to implement *MUL_LOHI for my processor.
My processor has mulxss (e.g.) that gives the 32 high bits of a 64 bit
multiply.
I tried this in ios2ISelDAGToDAG.cpp:
/// Mul/Div with two results
case ISD::SMUL_LOHI:
case ISD::UMUL_LOHI: {
SDValue Op1 = Node->getOperand(0);
SDValue Op2 = Node->getOperand(1);
AddToISelQueue(Op1);
AddToISelQueue(Op2);
unsigned Op;
Op = (Opcode == ISD::UMUL_LOHI ?...

[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.
