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). </body></html>
