| /* 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. */ |
