  22 # Note:
  23 #   Because GCC has its own make rules for crtbegin.o and crtend.o,
  24 #   we cannot use crtbegin.o and crtend.o rules.
  25 #   So we create crtbegin1.o and crtend1.o instead.
  26 #   Make sure the linker script include these two objects
  27 #   for building .ctors/.dtors sections.

  29 # Use -DCRT_BEGIN to create beginning parts of .init and .fini content
  30 # Make sure you are building crtbegin1.o with -O0 optimization,
  31 # otherwise the static function will be optimized out
