26 It tries to align to a 16 byte boundary by padding with 0x00000090
27 ints, rather than 0x90 bytes (nop). This generates trash in the
28 ".init" section since the contribution from crtbegin.o is only 7
29 bytes. The linker pads it to 16 bytes with a single 0x90 byte, and
30 two 0x00000090 ints, which generates a segmentation violation when
31 executed. This macro forces the assembler to do the padding, since
32 it knows what it is doing. */
