-Subject: [PATCH] xtensa: fix PR target/65416
-
-The issue is caused by reordering of stack pointer update after stack
-space allocation with instructions that write to the allocated stack
-space. In windowed ABI register spill area for the previous call frame
-is located just below the stack pointer and may be reloaded back into
-the register file on movsp.
-Implement allocate_stack pattern for windowed ABI configuration and
-insert an instruction that prevents reordering of frame memory access
-and stack pointer update.
