-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.

-
-	* config/arc/arc-protos.h (arc_pad_return): Remove.
-	* config/arc/arc.c (machine_function): Remove force_short_suffix
-	and size_reason.
-	(arc_print_operand): Adjust printing of '&'.
-	(arc_verify_short): Remove conditional printing of short suffix.
-	(arc_final_prescan_insn): Remove reference to size_reason.
-	(pad_return): New function.
-	(arc_reorg): Call pad_return.
-	(arc_pad_return): Remove.
-	(arc_init_machine_status): Remove reference to force_short_suffix.
-	* config/arc/arc.md (vunspec): Add VUNSPEC_ARC_BLOCKAGE.
-	(attr length): When attribute iscompact is true force to 2
-	regardless; in the case of maybe check if we want to force the
-	instruction to have 4 bytes length.
-	(nopv): Change it to generate 4 byte long nop as well.
-	(blockage): New pattern.
-	(simple_return): Remove call to arc_pad_return.
-	(p_return_i): Likewise.

-    [arm] PR target/86003 build failures with --with-cpu=xscale
-    
-    The XScale cpu configuration in GCC has always been somewhat
-    non-conforming.  Although XScale isn't an architecture (it's simply an
-    implementation of ARMv5te), we do by tradition emit a specific
-    pre-define for it.  We achieve this effect by adding an additional
-    feature bit to the xscale CPU definition that isn't part of the base
-    architecture.
-    
-    When I restructured the options last year I overlooked this oddity and
-    the result, of course, is that this configuration now fails to build
-    as intended.
-    
-    What happens is that the driver (correctly) constructs an architecture
-    for the xscale cpu name (as armv5te) and passes it in addition to the
-    CPU name.  The backend code, on finding both a cpu and an architecture
-    specifies attempts to correlate the two and finds a difference due to
-    the additional feature bit and reports an inconsistency (fatally if
-    -werror is specified).
-    
-    I think the best fix to this is to treat the xscale feature bit using
-    the same mechanism that we use for other 'quirks' in CPU
-    implementations and simply filter it out before comparing the
-    capabilities.  It has the additional benefit that it's also the
-    simplest fix.

-
-hs4x and hs4xd were mistakenly mentioned in MULTILIB_OPTION/DIRNAMES

-That breaks multilib toolchains building becase we're trying to compile

-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.
