# Note:

# Because GCC has its own make rules for crtbegin.o and crtend.o,
|
|
# we cannot use crtbegin.o and crtend.o rules.
|
|
# So we create crtbegin1.o and crtend1.o instead.
|
|
# Make sure the linker script include these two objects
|
|
# for building .ctors/.dtors sections.
|
|
|
|
# Use -DCRT_BEGIN to create beginning parts of .init and .fini content
|
|
# Make sure you are building crtbegin1.o with -O0 optimization,
|
|
# otherwise the static function will be optimized out
