[LLVMdev] TableGen backend support to express relations between instruction
...e and PredSense are the new fields added to the (Hexagon)
Instructions. Other targets can define their own relations and add new
fields if necessary. TableGen will output relations as a table which can be
queried using a function
getPredOpcode(Opcode, predsense) {
If (predsense == true)
return getPredOpcodeTable[Opcode][0]
if (predsense == false)
return getPredOpcodeTable[Opcode][1]
}
Let me know if something is not clear and I will try to explain it further.
Thanks,
Jyotsna

[LLVMdev] TableGen backend support to express relations between instruction
Jyotsna,
I hadn't been following this, so I apologize if this has already been
provided, but can you give a quick example of how this functionality is
used?
Thanks in advance,
Hal

[LLVMdev] TableGen backend support to express relations between instruction
Hi Jakob,
Here is the first draft of the patch to add TableGen backend support for the
instruction mapping tables. Please take a look and let me know your
suggestions. As of now, I create one mapping table per relation which
results into a long .inc file. So, I'm planning to combine everything into a
single table and will include APIs (one per relation) to query from this
table.
Thanks,
