[LLVMdev] TableGen backend support to express relations between instruction
Hi Hal,
I will try to explain the functionality using a simple example. Let's say
that we have three formats for 'ADD' instruction and we want to relate them.
ADD - non-predicated form
ADD_pt : predicate true
ADD_pf : predicate false
We can define the relationship between the non-predicated instructions and
their predicate formats as follows:
def getPredOpcode : InstrMapping { // InstrMapping is a new class defined in
Target.td
// Used to filter instructions that have this kind of re...

[LLVMdev] TableGen backend support to express relations between instruction

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,
