+=== 0001-RISC-V-Make-unique.patch ===
+From adce62f53d8ad00e8110a6a2de7962d7a850de16 Mon Sep 17 00:00:00 2001
+From: Keith Packard <keithp@keithp.com>

+Subject: [PATCH] RISC-V: Make unique SECCAT_SRODATA names start with .srodata
+ (not .sdata2)
 
+default_unique_section uses ".sdata2" as a prefix for SECCAT_SRODATA
+unique sections, but RISC-V uses ".srodata" instead. Override the
+TARGET_ASM_UNIQUE_SECTION function to catch this case, allowing the
+default to be used for all other sections.
+
+gcc/
+	* config/riscv/riscv.c (riscv_unique_section): New.
+	(TARGET_ASM_UNIQUE_SECTION): New.
