Subject: [PATCH] arc: Refurbish adc/sbc patterns
The adc/sbc patterns were unecessary spliting, remove that and
associated functions.
gcc/ChangeLog:
2020-10-11 Claudiu Zissulescu <claziss@synopsys.com>
* config/arc/arc-protos.h (arc_scheduling_not_expected): Remove
it.
(arc_sets_cc_p): Likewise.
(arc_need_delay): Likewise.
* config/arc/arc.c (arc_sets_cc_p): Likewise.
(arc_need_delay): Likewise.
(arc_scheduling_not_expected): Likewise.
* config/arc/arc.md: Convert adc/sbc patterns to simple
instruction definitions.

From 1557c3d919623a95c2aa090d3018c31401f63f88 Mon Sep 17 00:00:00 2001

Subject: [PATCH] libsanitizer: Remove cyclades from libsanitizer
The Linux kernel has removed the interface to cyclades from
the latest kernel headers[1] due to them being orphaned for the
past 13 years.
libsanitizer uses this header when compiling against glibc, but
glibcs itself doesn't seem to have any references to cyclades.
Further more it seems that the driver is broken in the kernel and
the firmware doesn't seem to be available anymore.
As such since this is breaking the build of libsanitizer (and so the
GCC bootstrap[2]) I propose to remove this.
