+Subject: [PATCH] PR bootstrap/87338: Fix ia64 bootstrap comparison regression
+ in r257511
+To: gcc-patches@×××××××.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.
