Is there a Xtensa LX6 emulator?

I want to port a compiler to produce code that will run on an ESP8266 and an ESP32. In order to run compiler tests, I'm looking for an open source LX6 emulator --- it doesn't need to emulate any of the hardware, just the CPU core. Does anyone know of one? Searching finds lots of hits of emulators for the ESP8266 and ESP32, but nothing about emulators of them...

I'd rather not have a full ESP platform emulator, if possible --- I just want to run code fragments, and having to produce full deployable binaries with serial drivers etc in them is a pain. Is there anything which just emulates the CPU core? Preferably a library I can embed into another application? Performance isn't an issue...
