| |
| <p>This is a fairly complete i860 assembler which is compatible with the |
| UNIX System V/860 Release 4 assembler. However, it does not currently |
| support SVR4 PIC (i.e., <code>@GOT, @GOTOFF, @PLT</code>). |
| |
| <p>Like the SVR4/860 assembler, the output object format is ELF32. Currently, |
| this is the only supported object format. If there is sufficient interest, |
| other formats such as COFF may be implemented. |
| |
| <p>Both the Intel and AT&T/SVR4 syntaxes are supported, with the latter |
| being the default. One difference is that AT&T syntax requires the '%' |
| prefix on register names while Intel syntax does not. Another difference |
| is in the specification of relocatable expressions. The Intel syntax |
| is <code>ha%expression</code> whereas the SVR4 syntax is <code>[expression]@ha</code> |
| (and similarly for the "l" and "h" selectors). |
