/* 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.  */
