# This is the small startup code that is first run when
# any static executable runs. A static executable is one
# that is started directly by the Linux kernel, not from
# the dynamic linker, it thus cannot depend on any shared
# library.
#
# It's purpose is to call __libc_init as defined in
# bionic/libc_init_static.c 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.
#
#    - address of the constructors table, i.e. a table
#      that points to various initialization and
#      finalization sections for the program.
