+
+@table @samp
+@item 32
+32-bit GP registers
+@item 64

+Set the amount of stack space reserved for arguments to functions.

+@cindex set ABI for MIPS
+Tell @value{GDBN} which MIPS ABI is used by the inferior.  Possible

+@cindex MIPS addresses, masking
+This command determines whether the most-significant 32 bits of 64-bit
+MIPS addresses are masked off.  The argument @var{arg} can be
+@samp{on}, @samp{off}, or @samp{auto}.  The latter is the default
