[xtensa][question] where is _Level1Vector defined ?

[williamtcdns]

I am currently trying to add a new xtensa config, and I am running into this error message:

zephyr/arch/arch/xtensa/core/libarch__xtensa__core.a(xtensa_asm2_util.S.obj): in function `_not_alloca':
/home/williamt/zephyrproject4/zephyr/arch/xtensa/core/xtensa_asm2_util.S:387:(.UserExceptionVector.text+0x12): dangerous relocation: j: cannot encode: _Level1Vector
zephyr/arch/arch/xtensa/core/libarch__xtensa__core.a(xtensa_asm2_util.S.obj): in function `_KernelExceptionVector':
/home/williamt/zephyrproject4/zephyr/arch/xtensa/core/xtensa_asm2_util.S:434:(.KernelExceptionVector.text+0x0): dangerous relocation: j: cannot encode: _Level1Vector

I cannot find where _Level1Vector is defined. Any idea ?
