@subsection PowerPC
+@value{GDBN} provides the following PowerPC-specific commands:
+
@table @code
+@kindex set powerpc
+@item set powerpc soft-float
+@itemx show powerpc soft-float
+Force @value{GDBN} to use (or not use) a software floating point calling
+convention. By default, @value{GDBN} selects the calling convention based
+on the selected architecture and the provided executable file.
+
+@item set powerpc vector-abi
+@itemx show powerpc vector-abi
+Force @value{GDBN} to use the specified calling convention for vector
+arguments and return values. The valid options are @samp{auto};
+@samp{generic}, to avoid vector registers even if they are present;
+@samp{altivec}, to use AltiVec registers; and @samp{spe} to use SPE
+registers. By default, @value{GDBN} selects the calling convention
+based on the selected architecture and the provided executable file.
