1 9.16.1 i860 Notes
1 -----------------
1 
1 This is a fairly complete i860 assembler which is compatible with the
1 UNIX System V/860 Release 4 assembler.  However, it does not currently
1 support SVR4 PIC (i.e., '@GOT, @GOTOFF, @PLT').
1 
1    Like the SVR4/860 assembler, the output object format is ELF32.
1 Currently, this is the only supported object format.  If there is
1 sufficient interest, other formats such as COFF may be implemented.
1 
1    Both the Intel and AT&T/SVR4 syntaxes are supported, with the latter
1 being the default.  One difference is that AT&T syntax requires the '%'
1 prefix on register names while Intel syntax does not.  Another
1 difference is in the specification of relocatable expressions.  The
1 Intel syntax is 'ha%expression' whereas the SVR4 syntax is
1 '[expression]@ha' (and similarly for the "l" and "h" selectors).
