+Subject: [PATCH 1/2] libasm: Fix one GCC7 -Wformat-truncation=2 warning.
+
+Make sure that if we have really lots of labels the tempsym doesn't get
+truncated because it is too small to hold the whole name.
+
+This doesn't enable -Wformat-truncation=2 or fix other "issues" pointed
+out by enabling this warning because there are currently some issues
+with it. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79448
