+# it's purpose is to call __libc_init with appropriate

+#
+# - the address of the raw data block setup by the Linux
+# kernel ELF loader
+#
+# - address of an "onexit" function, not used on any
+# platform supported by Bionic
+#
+# - address of the "main" function of the program. We
+# can't hard-code it in the adr pseudo instruction
+# so we use a tiny trampoline that will get relocated
+# by the dynamic linker before this code runs
+#
+# - address of the constructor list
