static

Print a list of module ports in the following form: in x: !firrtl.uint<1> [{class = "DontTouch}], out "_port": !firrtl.uint<2>

When there is no block specified, the port names print as MLIR identifiers, wrapping in quotes if not legal to print as-is. When there is no block specified, this function always return false, indicating that there was no issue printing port names.

If there is a block specified, then port names will be printed as SSA values. If there is a reason the printed SSA values can't match the true port name, then this function will return true. When this happens, the caller should print the port names as a part of the attr-dict.
