G (Big-endian)
Generate big-endian
code.
Compile for a target that uses big-endian memory. This option requires
that
Fcoff or Felf be in effect. This option is also passed to
gas960c/gas960e and gld960. When
G is specified, the preprocessor
symbol
__i960_BIG_ENDIAN__ is defined.
g (Debug)
Specifies debug
information.
g [
level
]
where
level
specifies the amount of debug information. Note that the
meaning of level varies depending on the object format in use, as
described below.
Using
g0 disables debug information. (This is the same as not using the g
option.)
For b.out and COFF, debug level settings of
g, g1, g2, and g3 all have the
same effect: they specify “normal” debug information.
When the default object-file format (b.out) is selected, DBX-style
symbolic debug directives suitable for use only with gdb960 are output.
For ELF/DWARF, debug level settings of
g, g1, and g2 all have the same
effect: they specify all DWARF debug information except preprocessor
macros.
