+Subject: [PATCH 1/1] 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.

9.3.0: increase expmed cache size from 10^3 to 10^6
Without this patch is takes dev-libs/xxhash 1-2 hours
to compile. With this patch - TODO measurements.
It workarounds deficiency of synth_mult() which evics
cache entries as it calculates optimal multiplication
algorithm. xxhash is especially hevyweight as it's a
64-bit multiplication of large prime constants.

+Note: upstream doesn't want to take this due to long standing behavior, and

+Subject: [PATCH] PR bootstrap/87338: Fix ia64 bootstrap comparison regression
+ in r257511
+To: gcc-patches@gcc.gnu.org
+
+By using ASM_OUTPUT_LABEL, r257511 forced the assembler to start a new
+bundle when emitting an inline entry label on. Instead, use
+ASM_OUTPUT_DEBUG_LABEL like for the block begin and end labels so tags are
+emitted rather than labels.
+
+gcc/
+ PR bootstrap/87338
+ * dwarf2out.c (dwarf2out_inline_entry): Use ASM_OUTPUT_DEBUG_LABEL
+ instead of ASM_GENERATE_INTERNAL_LABEL and ASM_OUTPUT_LABEL.
