-/* 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. */
