-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.

-Subject: [PATCH] [ARC] Reimplement return padding operation for ARC700.
-
-For ARC700, adding padding if necessary to avoid a mispredict. A
-return could happen immediately after the function start. A
-call/return and return/return must be 6 bytes apart to avoid
-mispredict.
-
-The old implementation was doing this operation very late in the
-compilation process, and the additional nop instructions and/or
-forcing some other instruction to take their long form was not taken
-into account when generating brcc instructions. Thus, wrong code could
-be generated.
-
