[LLVMdev] Emulate i64 add with 3 instructions
...c1_low32 + src2_low32 (unsigned add; dst_high
might contain the overflow bit)
dst_high32 = dst_high32 + src1_high32
dst_high32 = dst_high32 + src2_high32
I tried it with patterns like the following in InstrInfo.td (this is
obviously wrong, but you have to start somewhere):
def : Pattern<(set LLRegs:$dst, (add LLRegs:$src1, LLRegs:$src2)), [(set
LLRegs:$dst, (anyext (add (trunc LLRegs:$src1), (trunc LLRegs:$src2))))]>;
... but tablegen complains: "Cannot use 'add' in an output pattern!". Is
this the right way to do it - that is, defining a pattern for an
operation? ......
