/* The Solaris 2.0 x86 linker botches alignment of code sections.
It tries to align to a 16 byte boundary by padding with 0x00000090
ints, rather than 0x90 bytes (nop). This generates trash in the
".init" section since the contribution from crtbegin.o is only 7
bytes. The linker pads it to 16 bytes with a single 0x90 byte, and
two 0x00000090 ints, which generates a segmentation violation when
executed. This macro forces the assembler to do the padding, since
it knows what it is doing. */
