Subject: [PATCH] xtensa: fix PR target/91880
Xtensa hwloop_optimize segfaults when zero overhead loop is about to be
inserted as the first instruction of the function.
Insert zero overhead loop instruction into new basic block before the
loop when basic block that precedes the loop is empty.

Subject: [PATCH] Revert "re PR target/92095 (internal error with -O1
-mcpu=niagara2 -fPIE)"
This reverts commit 3fcce773f0f914c0499b130c6e9efa0e45ee54a0.
Building the Buildroot defconfig qemu_sparc_ss10_defconfig using
gcc 8.4, 9.3 and 10 produce a broken rootfs that trigger illegal
instruction messages.
gcc 8.3, 9.2 are the latest working gcc version.
git bisect between gcc 8.4 and 8.4 allowed to identify
the commit that introcuce the regression.
Reverting this patch allowed to produce a working rootfs.

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.
