Is there something similar to #ifdef … #endif in C supported in TableGen *.td files?

Not as such, what are you trying to do?

For example, sometimes I want some patterns to be matched by one machine
instruction and sometimes two or more. I am doing the development for an
experimental compiler and nothing is sure. I have source code in the backend
looking for some specific opcode and they are conditional compiled
(controllled by #ifdef..#endif).
Your best bet is to run cpp over the .td files before you run them through tblgen then.
For mainline development, we don't want to support this.
