Source Locators Missing from External Module Ports #5115
Description
Source locator information isn't showing up in the emitted FIRRTL text for the ports of external modules. Consider the following:
//> using repository https://central.sonatype.com/repository/maven-snapshots
//> using scala 2.13.18
//> using dep org.chipsalliance::chisel:7.5.0
//> using plugin org.chipsalliance:::chisel-plugin:7.5.0
//> using options -unchecked -deprecation -language:reflectiveCalls -feature -Xcheckinit
//> using options -Xfatal-warnings -Ywarn-dead-code -Ywarn-unused -Ymacro-annotations

class Baz extends BlackBox {
val io = IO {
new Bundle {
val a = Output(Bool())
}
}
}
class Bar extends ExtModule {
val a = IO(Output(Bool()))
}
class Foo extends Module {
val a = IO(Output(Bool()))
private val bar = Module(new Bar)
private val baz = Module(new Baz)
a :<= bar.a ^ baz.io.a
}
object Main extends App {
println(
ChiselStage.emitCHIRRTL(
gen = new Foo
)
)
}This produces the following FIRRTL:

connect a, _a_T @[/Users/$user/repos/github.com/seldridge/scala-snippets/NoInfoExtModule.scala 28:5]I'd expect to see the source info on the ports of the blackbox and extmodule. Not shown, but having this on the blackbox parameters would be good, too.
