| # 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 |
| crtbegin1.o: $(srcdir)/config/nds32/initfini.c $(GCC_PASSES) $(CONFIG_H) |
| $(GCC_FOR_TARGET) $(INCLUDES) \ |
| $(CFLAGS) \ |
| -DCRT_BEGIN \ |
| -finhibit-size-directive -fno-inline-functions \ |
| -O0 -c $(srcdir)/config/nds32/initfini.c -o crtbegin1.o |
| |
| # Use -DCRT_END to create ending parts of .init and .fini content |
| # Make sure you are building crtend1.o with -O0 optimization, |
| # otherwise the static function will be optimized out |
| crtend1.o: $(srcdir)/config/nds32/initfini.c $(GCC_PASSES) $(CONFIG_H) |

| |
| # Use this rule if and only if your crt0.o does not come from library |
| # Also, be sure to add 'crtzero.o' in extra_parts in libgcc/config.host |
| # and change STARTFILE_SPEC in nds32.h |
| # |
