+Subject: [PATCH 1/2] xtensa: Fix PR target/78118
+
+It started failing after the following commit: 32e90dc6a0cda45 ("PR
+rtl-optimization/61047").
+
+The change that made xtensa backend go ICE looks completely unrelated,
+and indeed, the issue is caused by the side effect of
+compute_frame_size() function call hidden in the
+INITIAL_ELIMINATION_OFFSET macro. This call updates the value of the
+xtensa_current_frame_size static variable, used in "return" instruction
+predicate. Prior to the change the value of xtensa_current_frame_size was
+set to 0 after the end of epilogue generation, which enabled the "return"
+instruction for the CALL0 ABI, but after the change the additional
+INITIAL_ELIMINATION_OFFSET calls make xtensa_current_frame_size non-zero
+and "return" pattern unavailable.
+
+Get rid of the global xtensa_current_frame_size and
+xtensa_callee_save_size variables by moving them into the
+machine_function structure. Implement predicate for the "return" pattern
+as a function. Don't communicate completion of epilogue generation
+through zeroing of xtensa_current_frame_size, add explicit epilogue_done
+variable to the machine_function structure. Don't update stack frame
+layout after the completion of reload.
