+Subject: [PATCH] implement arm eabi mem* functions
+
+these functions are part of the ARM EABI, meaning compilers may
+generate references to them. known versions of gcc do not use them,
+but llvm does. they are not provided by libgcc, and the de facto
+standard seems to be that libc provides them.
