+Subject: [PATCH] gcc: xtensa: fix fprintf format specifiers
+
+HOST_WIDE_INT may not be long as assumed in print_operand and
+xtensa_emit_call. Use HOST_WIDE_INT_PRINT_DEC/HOST_WIDE_INT_PRINT_HEX
+format strings instead of %ld/0x%lx. This fixes incorrect assembly code
+generation by the compiler running on armhf host.
+
+2017-05-28  Max Filippov  <jcmvbkbc@gmail.com>
+gcc/
+	* config/xtensa/xtensa.c (xtensa_emit_call): Use
+	HOST_WIDE_INT_PRINT_HEX instead of 0x%lx format string.
+	(print_operand): Use HOST_WIDE_INT_PRINT_DEC instead of %ld
+	format string.
