+Subject: [PATCH] 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

+GCC7 adds -Wimplicit-fallthrough to warn when a switch case falls through,
+however this causes warnings (which are promoted to errors) with the elfutils
+patches from Debian for mips and parisc, which use fallthrough's by design.
+
+Explicitly mark the intentional fallthrough switch cases with a comment to
+disable the warnings where the fallthrough behaviour is desired.
