+# this is the small startup code that is first run when
+# any executable that is linked with Bionic runs.
+#
+# it's purpose is to call __libc_init with appropriate
+# arguments, which are:
+#
+#    - 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
